2.0 Setup

This section provides information regarding the setup of the Rice Lake Weighing Systems BenchPro Retail scale.

2.1 Unpacking the Scale

Remove all contents from the packaging. Each carton contains the following:

• Scale with operator display attached
• In-line power supply
• U.S. power cord (three-prong AC power adapter)
• USB cable
• RS-232 cable
• Stainless steel/mild steel weigh platter

Inspect contents for damage. Contact Rice Lake Weighing Systems and the shipper immediately if items are damaged.

2.2 Scale Setup

1. Remove the protective cover from the weigh platter.
2. Place the scale on a sturdy, level surface near a power outlet. Ensure the scale and weigh platter are clear of obstructions.
3. Level the scale by adjusting the leveling feet until the bubble level (under the weigh platter) is within the circle.
4. Tighten the jam nuts on the feet of the scale, once the scale is level.

2.2.1 Display Mounting

A display mount is included with each scale and comes assembled to the scale's die-cast base housing. The included operator display uses two magnets to attach to the mount during use. The display mount can be detached from the scale and mounted to a table or on a wall.

4.3 Gravity Mode Setting

Gravitational variations may affect the accuracy of the BenchPro scale upon initial installation. The scale includes a feature which allows for adjustment of the gravity setting to the location and reducing the need for an initial calibration pending regulatory requirements in the region.

The BenchPro is a Legal for Trade device. Rice Lake Weighing Systems recommends contacting an authorized scale technician to perform a calibration using certified test weights.

IMPORTANT: Gravity compensation must be turned off when calibrating the scale with weights.

The factory default values are:

• Original Calibration Constant Setting: 9.7882 or 9.8056
• Local Calibration Constant Setting: 9.8056 (Rice Lake, Wisconsin)

NOTE: The original calibration gravity constant is the location the test weights were placed on the scale to calibrate it. The local calibration gravity constant is the location the scale is to be used.

To determine the local calibration gravity constant, use the Internet to identify the local latitude and altitude. Type these values into a gravity calculator to determine the local calibration gravity constant. The BenchPro uses four values to the left of the decimal place and it may be necessary to round the values prior to input.

Use the following steps to modify the local gravity (GrAU) constant setting.

1. See Section 4.2.2 on page 13 to access and configure parameters within the service menu.
2. Press F1 until GrAu displays.
3. Press UNITS to enter GrAU parameter. 'No' is the default.
4. Press F1 to change it to YES and then press UNITS. The original calibration gravity constant setting displays.
5. Press UNITS to accept. The local calibration gravity constant displays.
6. Press F1 to increase the flashing digit.
7. Press TARE to accept the value entered and move to the next digit.
8. Repeat Step 6 and Step 7 until the local calibration gravity constant is complete.
9. Press UNITS until Grau displays.
10. Press F1 until done displays.
11. Press UNITS to accept and save the setting. The scale returns to weigh mode.

Below are links to websites used to determine local latitude and altitude. Please note these website address's are provided for reference only and may change.

• National Geophysical Data Center: www.ngdc.noaa.gov
• Measurement Canada: www.ic.gc.ca
• Map Coordinates: www.mapcoordinates.net/

Once local latitude and altitude have been determined, use the following link to calculate local gravity:

www.sensorsone.com/local-gravity-calculator/

IMPORTANT: It is up to the authorized scale dealer to ensure the device is accurate at the intended point of use, especially for Legal for Trade installations.

5.0 Calibration

This section provides information regarding the calibration of the Rice Lake Weighing Systems BenchPro Retail scale.

5.1 Span Calibration

The BenchPro allows for calibration with weight values other than max capacity. Table 5-1 displays the alternate calibration weights for each model.

Calibration should only be performed using certified tests weights and performed by the local scale distributor.

NOTE: Turn off Gravity Compensation, See Section 4.3 on page 16 prior to performing a calibration using certified weights. The default capacity (CAP) setting is in lb, if using kg calibration weights, change the CAP to the appropriate scale capacity of the scale model. The model number of the scale is located on the serial tag on the bottom of the scale.

Table 5-1. Alternate Calibration Weights

1. See Section 4.2.1 on page 13 to access service menu. 2Его displays.
2. Press F1 until GrAu displays.
3. Press UNITS to accept. YES or no displays.
4. Press F1 to scroll to no.
5. Press UNITS to accept. Grau displays.
6. Press F1 until CAP displays.
7. NOTE: See Section 4.3 on page 16 to set Gravity compensation (GrAU) values if required.
8. Select the appropriate scale capacity from Table 5-1.
9. Press F1 to scroll to chosen capacity.
10. Press UNITS to accept. CAP displays.
11. Press F1 until CAL displays.
12. Press UNITS to accept. C2Ero displays.
13. With no weight on the weight platter, press UNITS to accept. A six digit value displays. This is the internal counts of the load cell at zero weight.
14. Press UNITS to accept and perform a zero calibration. C2Ero displays.
15. Press F1 once. CSPAn displays.
16. Press UNITS to accept. XXX lb or XXX kg displays.
17. Press F1 to scroll to the alternate calibrate weight value, if performing a calibration using certified weights.
18. Press UNITS to accept. I displays.
19. Place the calibration weight on the scale and wait for the value to stabilize.
20. Press UNITS to accept. The calibration data is saved and the scale returns to the weigh mode.

The weight value displayed must match the value of the calibration weight used. If not, perform the calibration a second time and follow each step carefully. If Err 1 displays, there is a calibration error. Ensure the correct calibration weight value was selected in comparison to the actual calibration weight used. See Section 7.1 on page 29 for more information on troubleshooting.

5.2 Linear Calibration

IMPORTANT: Only perform a linear calibration function if instructed by Rice lake Weighing Systems and an authorized scale technician.

The BenchPro includes an optional linear calibration feature. This is an additional feature to perform after a span calibration has been completed at maximum capacity and linear calibration is performed with two lower calibration weight values.

1. See Section 4.2.1 on page 13 to access service menu. 2Erob displays.
2. Press F1 until Grau displays.

17. Press F1 to select the Point I value (amount of test weight needed on scale for calibration of Po int 1).
18. Press UNITS to accept value. I displays.
19. Place the Point I weight on the weigh platter and wait for the value to stabilize.
20. Press UNITS to accept and calibrate at Point 1.
21. Point2 briefly displays, followed by the Po int2 weight value. Remove Point I test weights.
22. Press F1 to select the Point2 value (amount of test weight needed on scale for calibration of Po int2).
