(The firmware version is displayed when the readout is powered on using the ON/OFF key.) These readout models may be supplied as part of ProScale linear encoder system, as a free-standing readout for use with any Digimatic compatible products, or as part of a turn-key measuring gage built and supplied by Accurate Technology, Inc. Videos showing many features of these readouts are available at www.proscale.com be sure to search by your readout's Part Number to see features that are available for each model. (If your readout has a QR label, you can scan the label to go directly to the correct web page.) The readouts covered in this Manual are compatible with electronic scales that have the following colors and patterns: Green `zig-zag' pattern is used on ProScale Models 150B, 250B, 950, 150G, and 250G Absolute Series measuring systems. For this scale pattern, programming parameter Pr14 should be set to 1. Black `stripes' pattern is used on ProScale Models 190, 290, 390 & 590 systems Inductive Series II measuring systems. For this scale pattern, programming parameter Pr14 should be set to 0. Blue `stripes' pattern was used on ProScale Models 180, 280, 380 & 580 systems Inductive Series I measuring systems made 2007 to 2012. For this scale pattern, programming parameter Pr14 should be set to 0. Green `stripes' pattern was used on ProScale Models 100, 200 systems made from 1989 to 2010. These readouts have limited compatibility; not recommended for long term use. Note: This manual is not meant to be 100% comprehensive. There are too many possible uses for these products to address every possible application. Further, the development of these readouts is forever ongoing, and features are being added all the time.

Using Velcro or double-sided tape 2. Use the 3 punch-out holes inside case. Mount readout to machine/panel using #6 or M4 flathead screws. 3. Use any (or all) of the six holes on the back of the readout. Mount using 4-40 or M2 screws. Operation Manual for ProScale LCD Readouts, version 4 Page 8 of 40 Power and Input-Output Connections These readouts are powered by a single CR123 lithium battery. Unless specially ordered, the readout will deliver to you with the battery installed. New for this version readout: A battery indicator will appear on the left side of the LCD screen. There are 3 tiers of battery shown, which represent the voltage level of the battery. When only one tier is left, a new battery should be prepared for installation. Typical battery life for these readouts is 7 months, but life will depend on how often the readout is being used, and which programming options are enabled. Battery Replacement: Remove the 2 screws in the upper right and lower left corners of the readout. Lift the cover off. Remove the old battery and install a new battery, noting the proper orientation. Replace the cover and screws. External Power: These readouts also support use of external power if: 1. The scale type is any model except Model 150B or Model 250B type. (Consult factory for assistance if scale type is not known.) 2. The input power is 12 24 volts DC. (AC power sources are not supported.) 3. The 3-position male terminal plug for the readout has been supplied. 4. Common for the machine and the readout must be the same. A "hot chassis" condition may permanently damage some or all of the electronics. New for this version readout: If external power is used, but a power loss occurs, the readout will automatically switch to battery power (if a battery is installed). The readout will automatically switch back to external power when it is restored. Manual Part # 800-1413-001 Revision 6-12-23 Page 9 of 40 Initial Setup Follow these steps to configure your readout for initial use: 1. When the readout is first powered on, it may show a No Enc message. This means there is not an encoder connected to the readout. To clear the message, connect a compatible encoder. Note: Encoder must be installed onto scale first. 2. When an encoder is first connected, the readout may show No Pos. This informs the user that a position has not been programmed yet. For the initial setup, use the DATUM, and PLUS keys to set a POSITIVE starting value. (Any POSITIVE value will work for now.) 3. Choose the units that will be initially used (millimeters, inches, or fractions). Each press of the UNITS key will change the units that are displayed. (The screen will show the units description each time the UNITS key is pressed.) 4. Check the reading direction: a) With the readout showing a POSITIVE number on the screen, move the encoder system a short distance. b) Take note if the displayed value increased or decreased. c) If the displayed value got larger/smaller, and this IS correct for your installation, no further steps are needed. d) If the displayed value got larger/smaller, and this IS NOT correct for your installation, the reading direction needs to be reversed. This can be accomplished two ways: i. If your encoder system is a Model 19, 29, 190, 290, 390, or 590 type, you can rotate the encoder 180 degrees on the scale. ii. If the encoder cannot be rotated, or if the encoder is a Model 150 or Model 250 system, the reading direction must be reversed using the programming mode, parameter Pr2. See pages 26-27 for making programming changes. 5. Calibrate the readout. Since there are many thousands of applications for ProScale systems, all calibration methods cannot be described here. However, the general steps are the same. a. Determine what value the readout should be showing. b. Use the DATUM, PLUS, and MINUS keys to adjust the reading on the screen to match desired value. NOTE: To rapidly adjust the value, press and hold the PLUS or MINUS key down. (The update speed will increase every 2 seconds the key is held.) Operation Manual for ProScale LCD Readouts, version 4 Page 10 of 40 Primary keys on the readout All the primary keys on the keypad have multiple functions. What happens on a QUICK PRESS of each key? Key Action ON/OFF The readout turns on or off. UNITS The units change. Note: Available units can be restricted with custom programming settings. PLUS The displayed value is increased one unit. DATUM The displayed value is set to the pre-programmed datum value. Note: This value is zero by default, but it can be custom programmed to be any value. MINUS The displayed value is decreased one unit. What happens if a KEY IS HELD DOWN? Key Action ON/OFF Nothing UNITS Nothing PLUS The displayed value increases faster each 2 seconds. DATUM After 4 seconds, the battery voltage is displayed. After 7 seconds, the readout's temperature is displayed. MINUS The displayed value decreases faster each 2 seconds. Key COMBINATIONS: For these actions, press and hold the first key, then quickly press and release the second key. (This action is the same as making a capital letter on a computer; the first key acts like SHIFT.) Press and hold Then quickly press and Action release ON/OFF UNITS LOCK (or unlock) the keypad. UNITS DATUM Enters or exits the programming mode. UNITS PLUS Adds one segment to displayed value. (Models 150/250 only.) UNITS MINUS Adds one segment to displayed value. (Models 150/250 only.) Note: Additional key combinations exist, and more detail is provided later in this manual, where applicable. Manual Part # 800-1413-001 Revision 6-12-23 Page 11 of 40 Supplemental keys Some readout models have a supplemental keypad that allows additional features to be used. See below for functions of these keys: Key ABS/INC SEND F1 F2 F3 F4 Quick press action When in ABS mode, no action. When in INC mode, the INC value is reset. The currently displayed value is sent to the SPC port. An offset value is applied. (If offset feature is enabled in the programming menu). Press and hold action When in ABS mode, toggles readout to INC mode. When in INC mode, toggles readout back to ABS mode. None None Also used to store compensation point data in Enhanced readouts. Used to set compensation end point for Enhanced readouts. Turns Monitor mode on or off. (If monitor feature is enabled in the programming menu.) None None Starts editor for Go/NoGo editor. (If Go/NoGo feature is enabled.) Turns HOLD mode on or off. (If hold feature is enabled in the programming menu.) None Edits values in Go/NoGo editor. (If Go/NoGo feature is enabled.) Operation Manual for ProScale LCD Readouts, version 4 Page 12 of 40 What do all the Symbols mean? Symbol Meaning The digital readout is operating in Absolute measurement mode. The digital readout is operating in Incremental (temporary) mode. Press and hold ABS/INC key 3 seconds to go back to ABS mode. The readout is in LOCK mode. This prevents loss of calibration if PLUS, MINUS, or DATUM keys are pressed. See page 11 for key combination to turn this off. The readout's display is frozen. When this feature is enabled, press F4 key to turn on/off. Monitor mode (drift alarm) is turned on. When this feature is enabled, press F3 key to turn on/off. When any of these are displayed, the readout is adding a programmed offset value to the primary dimension. Offsets are useful for applications with multiple fixed data points. These are used with 16th and 32nd fractional inch modes. Each bar represents an extra 1/64th long/heavy on the dimension. Manual Part # 800-1413-001 Revision 6-12-23 Page 13 of 40 Symbols (continued): When using fractions over 99 inches, one (or both) of these will light to show a value over 100 inches. For example: measurement is 205 5/16. The readout will show 5 5/16 and turn on the +200 indicator. Minus sign. Turns on when a negative value is displayed. Battery level indicator. When all 3 bars are lit, your battery is good. When only bottom bar is lit, a new battery is needed soon. Vinculum used in fractions mode to separate numerator from denominator. Units indicator. IN is for INCHES or fractions. MM for millimeters. CM for centimeters. (Press UNITS key to change.) Operation Manual for ProScale LCD Readouts, version 4 Page 14 of 40 Operation & Customizable Features All of the keys on the readout have multiple functions and some also have key combinations for extra controls. See pages 11-12 for more information about how the keys work separately and in combination. Some customization and operation features require changing parameters in the programming menu. See pages 26-32 for more information about using the programming menu. Automatic power off: To prolong battery life, the readout has a built-in timer that turns off the LCD screen after 15 minutes of inactivity. If you wish to shorten or extend this timer, use the programming menu to change parameter Pr12 (see pages 26-28). Automatic power on: If the LCD is off, and there is motion greater than 0.10mm (.004 inches), the screen will wake up automatically. If you wish to increase this amount, use the programming menu to change parameter Pr5 (see pages 26-27). Available units: By default, the readout can display measurements in millimeters, decimal inches, fractional inches (16th, 32nds, and 64ths). If you wish to restrict the units available for display, use the programming menu to change parameter Pr11 (see pages 26-27). Resolution: By default, the readout displays millimeters to 2 decimal places, and decimal inches to 3 places. If you wish to change the resolution of displayed measurements, use the programming menu to change parameter Pr4 (see pages 26-27). NOTE: The display will auto-range when needed. For example, if you configure the readout to show 4 decimal places in inches, but the measurement exceeds 99.9999 inches, the LCD screen does not have enough characters to show all digits. The readout will automatically reduce the decimal places to 3 when this happens. LOCK: A user can "lock-out" the position adjustment keys (PLUS, datum & MINUS) to prevent accidental changes of the displayed value. See page 11 for the proper key combination. The word LOCK will display in the upper left corner of the LCD. To deactivate this Key Lock, use the same key combination. NOTE: Key Lock may also be enabled using the programming menu, parameter Pr3 (see pages 26-27). In some cases, both changing parameter Pr3 to 0, AND the key combination may be needed to unlock the readout. Manual Part # 800-1413-001 Revision 6-12-23 Page 15 of 40 Linear Scaling: In some installations, it may be desirable to apply a linear adjustment. For instance, you may want to fine-tune the system using a small adjustment value like 0.99999. Or, you may want the readout to display double the actual motion made by the encoder using a value like 2.00000. Both parameters Pr13 and Pr16 can be used for this purpose. See pages 26-28 to change these, and pages 23 for more information on when to use each of these settings. Segment Correction: When using ABSOLUTE SERIES type scales, the maximum slew rate (how fast encoder can be moved) can be as low as 10 inches per second (depends on encoder used and which features of the readout are turned on). If the encoder is moved too quickly, the readout can lose its count of scale "segments". When this happens, the displayed value will be incorrect by 430mm (either too large or too small, based on the direction of travel). If this happens, the displayed value can be quickly corrected: · To add one segment to the displayed value: Press and Hold UNITS key and then Momentarily press the + key. The display will increase by 430.08mm (16.933 inches). · To subtract one segment from the displayed value: Press and Hold UNITS key and then Momentarily press the key. The display will decrease by 430.08mm (16.933 inches). Note: Segment correction only works when programming parameter Pr14 is configured to 1. Limits: The readout can be programmed to alert the user when an upper or lower limit is reached. To enable this feature, use the programming menu to change parameter Pr27 to a value of 1 (see pages 26-30). Program the lower limit value in parameter Pr28. Program the upper limit value in parameter Pr29. During normal operation (between the limit values), the LCD will show the current measurement. When the displayed position moves outside the limits, the readout will alternate the position with either HI LMT or LO LMT on the screen. The readout can also output a signal when limits are exceeded. This requires a male terminal strip be added to the readout and wired to common and I/O pin, as shown on page 9. (The output signal is set to NO or NC by parameter Pr37.) Angle: The readout can be configured to compute and display angular measurements over a limited range (85 to 95 degrees). A ProScale linear encoder is the only input supported for this application. Operation Manual for ProScale LCD Readouts, version 4 Page 16 of 40 Absolute / Incremental modes: (Not available on the Basic readout) The readout has two measurement indexes. One is called ABS (absolute) and the other INC (incremental). The ABS measurement is the reference distance to a fixed or known position. The INC measurement is a temporary point-topoint distance used only to make incremental/relative movements from one position to another. These modes are analogous to the odometer and tripmeter in your car. The readout automatically enters ABS mode when power is first applied. This is indicated by ABS shown in the upper left corner of the LCD. To enter INC (Incremental) mode, press and hold the ABS/INC key for 3-4 seconds. The ABS indicator will turn off and an INC indicator will turn on. When INC mode is initially entered, the displayed position will change to reflect a new reference point at the current position of the encoder. This is typically a position of zero but may be changed by using the + or keys to enter an offset. Moving the encoder in either direction will display the distance moved from the initial INC starting point (plus any offset). To complete another incremental measurement from the new position, quickly press and release the ABS/INC key. The readout will again change to zero (or the previously programmed offset). To return to the ABS mode, press and hold the ABS/INC key for 3-4 seconds. NOTES: 1. If you frequently use the INC mode, you can change the timing for the ABS/INC key press. Set programming parameter Pr22 to a 1. 2. The INC mode is meant to be temporary. This key should never be used to set a gage's absolute zero point. Send (Not available on the Basic readout) The readout has an output port that can be used to send measurement information to another device via a wireless transmitter or wired data converter. After connecting a transmitter to the 10-pin output connector on the readout, the user can initiate the data transmission by momentarily pressing the SEND key. Pressing this key will cause SEND to appear on the screen for 1 second; this shows activation of the send function (even if no device is attached to the readout). NOTES: · All inch modes are transmitted as decimal inches. · All metric modes are transmitted as millimeters. · Wired devices should not be used if the encoder type is Model 150B or Model 250B. Manual Part # 800-1413-001 Revision 6-12-23 Page 17 of 40 Offset Addition (Not available on the Basic readout) Some applications have multiple fixed reference positions to keep track of. The readout can be used to apply numerical offset values to the primary absolute position (the primary is the distance from the "main" zero point to the encoder's current place). The Offset Addition feature allows the readout to track up to 5 reference positions, and for the user to switch between these positions using the F1 key. To enable the Offset Addition feature, first determine how many total reference positions you need to track. Subtract one from the total, then program this number into parameter Pr30. For example, imagine you have one primary reference position, plus a second fixed position that is 5.225 inches away, and also a third fixed position that is 15.625 inches from the primary. Enter the programming menu (see page 26) and go to Pr30 (page 30). Set to this a value of 2 (because there are 2 extra reference positions). Next, program Pr31 to +5.225 inches, and program Pr32 to +15.625 inches. Exit the programming menu. After the readout is calibrated for the distance to your primary reference: · Press the F1 key to apply the first offset. The readout will add 5.225 inches to the primary value. You will also see a small 1 appear above the measurement. · Press the F1 key again to apply the second offset. The readout will add 15.625 inches to the primary value, and a small 2 will appear above the measurement. · Press the F1 key again to show the primary value (no offsets applied). NOTES: · If more than 4 offsets are needed, a special firmware version can be used that allows up to 7 offsets. · All offset values are with reference to the primary (not the previous offset). · Offset values are considered with the Enhanced readout when temperature compensation is enabled. Operation Manual for ProScale LCD Readouts, version 4 Page 18 of 40 Operation: Advanced Functions (Not available on the Basic readout) Advanced functions allow the readout to perform special tasks using the F1, F2, F3, and F4 keys. These special tasks must be enabled using programming parameter Pr24. The table below provides a summary of the functions available. Programming Parameter Pr24 Value 0 1 2 3 4 Function No Advanced Functions. F3 = MON F4 = HOLD Go / NoGo operation Not used Not used Monitor (Drift Monitoring) (parameter Pr24 set to 1) The readout can be used to monitor a position (to detect drift or variance). To activate the monitor mode, first set programming parameter Pr24 to 1. After this is activated, position the measuring system at the desired location, then momentarily press the F3 key. The MON symbol will illuminate on the LCD to indicate the monitor mode is active. If the measuring system moves more than 0.25mm in either direction, all digits on the screen (plus the MON indicator) will flash. If the measuring system is moved back into position, the flashing will stop. To exit the monitor mode, momentarily press the F3 key. The MON symbol will turn off. Notes: 1. The range of allowable motion can be customized using programming parameter Pr26. 2. Monitor can only be activated while in the normal ABS measuring mode. If incremental mode is activated (or if the readout enters programming mode or calibration mode), the readout will automatically exit monitor mode. 3. The readout can output a signal if the monitor alarm is triggered. This requires a male terminal strip be added to the readout and wired to common and I/O pin, as shown on page 9. 4. If the monitor mode is enabled and the programmable output is configured for drift monitoring (programming parameter Pr38), the output will not become active until the monitor alarm is triggered for at least 2 seconds. Manual Part # 800-1413-001 Revision 6-12-23 Page 19 of 40 Hold The readout provides a feature that allows the displayed measurement or position to be frozen, or put on "hold". This allows information to be captured on the readout for later viewing, regardless of the current encoder position. To activate the monitor mode, first set programming parameter Pr24 to 1. To activate the HOLD feature, momentarily press the F4 key. HOLD will be displayed in the upper left corner of the LCD. The currently displayed position and most key presses will be held. To release the HOLD feature, momentarily press the F4 key again, or cycle power using the ON/OFF key. NOTES: · If power is cycled when HOLD is active, any key presses (such as units, datum, + or ) while in HOLD will be executed when power is restored. · Leaving the normal measurement mode, (i.e. enter programming mode or calibration mode) causes the readout to automatically exit HOLD. Operation Manual for ProScale LCD Readouts, version 4 Page 20 of 40 Go/NoGo In certain applications, it may be desirable to program upper and lower measurement tolerances to measure parts. If the measurement falls within the programmed tolerance, a "Go" condition occurs. If the measurement is not within the upper or lower tolerance, a "No Go" condition occurs. To activate the Go/NoGo mode, first set programming parameter Pr24 to 2. To activate the monitor mode, first set programming parameter Pr24 to 1. Programming Parameter Pr25 should also be set to the number of target positions. For example: You have 4 parts you want to use the Go/NoGo feature for. Enter programming menu and set Pr24 to 2, then set Pr25 to 4. Setting up the Go/NoGo Ranges The readout can store up to 32 measurement targets, each with its own unique upper and lower tolerance. Each measurement target is identified with a number from 1 to 32. The Go/NoGo Editor is used to enter individual upper and lower tolerances for each measurement target as follows: 1. Press F3 to enter the editor. The LCD will display GO 1 (the 1 represents the first measurement target to be edited). 2. If this is the measurement target you wish to edit, proceed to step 3 below. If you wish to edit a different target, press the F3 again until the target you want to edit is displayed. 3. Press and hold the UNITS key, then momentarily press the F4 key. The LCD will display GO x U for 1 second. The U represents the upper tolerance for this target. Use the + and keys to set an upper limit. 4. Momentarily press F3. The LCD will now display GO x L for 1 second. The L represents the lower tolerance for this target. Use the + and keys to set a lower limit. 5. Press F3 to edit the next target's upper and lower values. 6. When done editing values, either: Press F3 over and over until you reach end of the target values, or Press and hold the UNITS key, then momentarily press the F4 key. The readout will show Go OFF. Operation of Go/NoGo Feature To count up through the list of measurement targets, press F3. To count down through the list of measurement targets, press F4. The Go/NoGo feature is activated immediately after a target is selected. Manual Part # 800-1413-001 Revision 6-12-23 Page 21 of 40 If the measurement is in tolerance, the readout will show the measurement for 2 seconds, then GO. If the measurement is out of tolerance, the readout will show the measurement for 2 seconds, then No Go. Notes: · Once a measurement target is selected, the LCD will alternate between the current position and GO or No Go depending on the current position and programmed tolerances. · The readout can output a signal when GO is displayed. This requires a male terminal strip be added to the readout and wired to common and I/O pin, as shown on page 9. A light or siren could be connected and activated to provide additional feedback for an operator. · When Go or NoGo is activated, and the programmable output is configured for Go/NoGo (programming parameter Pr38), the output will become active immediately. Operation Manual for ProScale LCD Readouts, version 4 Page 22 of 40 Using Compensation Features Your ProScale digital readout has several compensation tools built-in. See table below for the available features: Basic General Enhanced 950 Primary linear correction Yes Yes Yes Yes Non-linear (segmented) correction No No Yes No Temperature compensation No No Yes No Secondary linear multiplier Yes Yes Yes Yes Primary linear correction is most commonly used to correct for linear (coarse) error of the linear scale and/or the installation. For instance, if the system reads +.005" over 5 inches, and .010" over 10 inches, and .015" over 15 inches, this could be corrected using linear compensation. Using a multiplier of 0.999, the accuracy at all these locations would be nearly spot on. We recommend using programming parameter Pr13 for this. Non-linear compensation (sometimes called segmented compensation) is used to correct errors that the primary linear cannot fix. For instance, if the system read +.005 at 5 inches, but -.005 at 10 inches, use of only the primary linear correction cannot suitably fix the error. More about non-linear compensation programming is on page 16. Temperature compensation (sometimes called thermal compensation) is used to correct variation of the entire measuring system due to changes in ambient temperature. For instance, if a ProScale system is mounted to an aluminum benchtop, the entire system will grow/shrink as temperature changes. This expansion can be corrected using programming parameters Pr41 and 44. Keep in mind that this feature corrects for the gage, but not for the product being measured. Secondary linear multiplier is most commonly used to apply a final multiplier to all the corrected values. For example, if you were measuring the length of Vbelt between two points, you might use primary linear, non-linear, and temperature compensation to optimize total gage accuracy. But since the V-belt has 2 lengths which are simultaneously measured between 2 points, the secondary linear multiplier could be used to make the readout show the total belt length. If in doubt about which multiplier to use, and how they interact, please consult factory for assistance. Manual Part # 800-1413-001 Revision 6-12-23 Page 23 of 40 Using an External Input The readout supports using an external pushbutton, footswitch, etc to trigger a regular display function.

It should only be switched from OPEN to GROUND. Operation Manual for ProScale LCD Readouts, version 4 Page 24 of 40 Programming Mode (customizing the readout features) Many functions of the digital readouts are user programmable and may need to be configured to optimize operation. Resetting All Parameters Resetting all parameters is not necessary if you wish to customize your system. Caution: This step is not reversible. If you have purchased a complete product (turnkey gage, stop and fence system, etc.), some parameter settings differ from factory values. (Special parameter settings for your product are detailed inside the front cover of the original user manual.) To reset all parameters to the FACTORY defaults: 1. Turn the readout power off with a quick press of the ON/OFF key. 2. Open the readout case and ensure the PGM ENABLE jumper connects pins 1 and 2. (This jumper is just to left of the negative battery terminal.) 3. Press and Hold the ON/OFF and UNITS keys for 20 seconds. Press & Hold During these 20 seconds, the readout will: 1. Perform a full LCD segment test. 2. Reset all programming parameters to factory default values. 3. Display the firmware version of the digital readout. After the firmware version displays, the reset is complete, and the keys may be released. Be sure to program critical values before putting readout into service. Manual Part # 800-1413-001 Revision 6-12-23 Page 25 of 40 How to Enter Programming Mode Before making changes, open the readout case and verify the programming menu is accessible. The jumper to the left of the battery has three pins. Ensure pins 1 and 2 are connected with a shunt before proceeding. (After making changes, you can move the shunt to pins 2 and 3 to prevent further programming changes.) Note: The programming menu uses the active measurement units when it is started. If you prefer to configure the readout in inches, be sure the screen is showing measurements in INCHES before these steps. To start the programming menu, turn on the readout. 1. Press and hold the UNITS key. 2. Quickly press and release DATUM key. You will see PG on, then Pr1. 3. Release the UNITS key. 4. After a moment, the value for Pr1 will display.

Operation Manual for ProScale LCD Readouts, version 4 Page 32 of 40 Non-linear compensation The non-linear compensation function is used to enhance the basic accuracy of a ProScale based system by creating a table of correction values in the readout. These correction values are based on known measurement points along the length of the measurement system. The compensation table can hold up to 126 correction values. This feature is only available on Enhanced type ProScale readouts. Several products - including ProPanel and ProTable - have had this process completed at the factory prior to shipment. It is not necessary to repeat the initial error compensation procedure unless a system component has been replaced (readout or electronic scale). However, if there is reason to believe a product could have been damaged, repeating this process is encouraged. For ProKit Model 590 owners, the initial error compensation procedure should be performed following installation in order for the correction values to be meaningful. Preparing for non-linear compensation Your digital readout MUST BE IN ABSOLUTE MODE for the calibration data to be useful. (If the readout is in INC mode, press and hold the ABS/INC key until the ABS indicator lights in the upper left corner of the LCD.) Before beginning the non-linear error compensation procedure, you need to determine how many points to correct at. You also need to determine at what interval to compensate. The readout can store up to 126 correction points. The smaller the compensation interval (more points), the smoother the corrected calibration curve will be. However, this equates to more time spent, and more gage blocks required. Quality measurement standards such as square or rectangular Gage Blocks should be used. Keep in mind, however, that you will need a sufficient number of standards to create the number of points you decide to correct. Example: For a measuring system 100 inches long, the smallest interval that can be corrected is .800 inches, (100 ÷ 126). This means you will need sufficient standards to create a known measurement correction point EVERY .800 inches. A more realistic approach would be to use an interval of 2.000, 2.500, or 5.000 inches to create fewer compensation points. Manual Part # 800-1413-001 Revision 6-12-23 Page 33 of 40 Performing the non-linear compensation process The following example uses 5.000 inch gage blocks and a ProTable-SA Linear Measuring Machine. Other applications would follow a similar procedure. 1. Access the programming menu and set parameter Pr39 to a value of 1. Also set parameter Pr40 to your compensation interval. (For this example, the setting is 5.0000 inches.) 2. Exit the programming menu. 3. Turn off the readout using the ON/OFF key. 4. Press and hold the DATUM key and the ON/OFF key until the readout powers on (about 10 seconds). The screen will power on, show the firmware version, then show CAL. 5. The current position and the CAL message will alternate on the screen. This indicates the readout is ready to start recording compensation points. This alternating display will continue throughout the calibration process. 6. Place the measuring system's moving carriage against the fixed jaw/stop. Press the DATUM key to zero the measurement. 7. Press the F1 key. This enters the first correction point into the table. The LCD will momentarily show CO 0. This indicates the zero position entry was accepted. The display will then briefly display the next expected position (5.0000 in this case). 8. Open the carriage, and place the first measurement standard (5.000 inches) between the jaws. Close the moving carriage until the face of the jaw gently touches the standard. Press the F1 key. The LCD will show CO 1 indicating the first measurement point has been digitized. The display will briefly display the next expected position (10.0000 in this case). Note: If the screen shows BAD PT, press F2 key to exit the calibration process; see next page for details. 9. Open the carriage, and insert another measurement standard (total of 10.000in) between the jaws. Close the moving carriage until the face of the jaw gently touches the standard. Press the F1 key. The LCD will show CO 2 briefly. The display will then briefly display the next expected position (15.0000 in this case). 10. Repeat above steps with additional standards placed end-to-end every 5.000" (pressing F1 key each time) until the maximum measuring range has been achieved. 11. After the last correction point has been digitized by pressing F1, end the calibration process by pressing the F2 key. The LCD will Operation Manual for ProScale LCD Readouts, version 4 Page 34 of 40 momentarily show CO E. This indicates that the calibration process has ended. The readout will immediately return to normal operation. Notes about the calibration process · If you see BAD PT during the process, either the setting for programming parameter Pr40 does not match the gage bars used, or the product has too much error to be calibrated. · During the calibration process you may want to verify the NEXT correction point to be saved. This can be accomplished by momentarily pressing the F3 key. The LCD will display the next expected value to be programmed. · If an error is made during the calibration process where an incorrect entry is recorded press the F4 key to back up one position. Operating in Compensated mode After a successful correction table has been programmed, the readout will operate normally and the measuring system will have a higher level of accuracy. If the system is positioned outside the calibrated (corrected) range of operation, the LCD will display NO CO alternately with the current position. This is normal, and indicates that the system is operating outside the zone where it was calibrated. For example, if you calibrated from 0-100 inches, and the readout is showing -.001 inches, or 100.250 inches, the NO CO message is expected. If you choose to turn off non-linear compensation (set Pr39 to 0) the compensation table will be saved in memory. NOTE: Resetting the digital readout to factory defaults does not erase the compensation table. Manual Part # 800-1413-001 Revision 6-12-23 Page 35 of 40 Locking out access to the programming menu After all changes are made to the programming menu, access can be blocked by changing the position of a jumper on the circuit board.
