Calibrator Features
the measured value as a percentage of the range you have selected. This is also true for reversed (negative) readings. The calibration procedures use the secondary reading when setting calibration values. Note: The advanced options can affect the secondary reading percentage value relationship with the measured value shown in the primary reading. For example 8 mA = 50% with FLOW selected or 8 mA = 25% with LIN selected in the 4-20 mA range.
1.4.6 Positive and Negative Measurement The Calibrator has red (positive) and black (negative) connections to show polarity of connection, but it will measure in both positive and negative polarity. The primary and secondary readings will show a negative symbol for reverse polarity readings. Note: Current sourcing is only in positive polarity.
1.4.7 Current Range Selection The Calibrator has two current range options: 4-20 mA or 0-20 mA.
1.4.8 Date, Time and Calibration Date You can set the current date and time in the Calibrator and the calibration date. The Calibrator can then calculate how many days until calibration is due. The screen will show `CAL DUE’ when calibration is due.

Figure 1-8: Loop Resistor and 24 V Supply

Chapter 1. Introduction and Description
In a process control or measurement loop, a resistor of between 230 and 600 ohm is necessary for communications to work correctly with HART instruments. The Calibrator has an internal 24 V supply and a nominal 250 ohm loop resistance in series that you can enable or disable. The Calibrator can then work as a loop supply, resistor and measuring instrument, so an external resistor and loop supply is not necessary. You can disable one or both of these features if you have an external voltage source and resistor. Note: You must enable the internal 24 V supply or have an external loop supply for the Calibrator to control current. 1.4.12 Calibrator Information
Figure 1-9: Information Symbol Use the Calibrator Settings to show important Calibrator information such as the firmware version (APP VER) or battery voltage of the Calibrator. See “Settings” for more details. 1.4.13 Data Logging The Calibrator can log the data from your tests at set intervals and durations. See “Data Logging” on page 32 for more details. 1.4.14 Calibration The Calibrator has a PIN-protected procedure for checking and adjusting its calibration using suitable external calibration equipment. See “Calibration Procedures” on page 35 for more details. 1.4.15 Firmware Update The Calibrator has a PIN-protected procedure for upgrading its firmware using a suitable PC and the USB cable supplied with the Calibrator. See “Updating the Firmware” on page 48.

4. Calibration Procedures
Druck can provide a calibration service that is traceable to international standards. We recommend that you return the instrument to us or an approved service agent for calibration. If using an alternative calibration facility, check that it uses the same standards.
4.1 មុនពេលចាប់ផ្តើម
1. Check that the Calibrator battery level is at maximum. Consider changing to new batteries if not.
2. Make sure the calibration environment has a stable temperature of 21 ± 1°C (70 ± 2°F). 3. Make sure your calibration standard instrument has these ranges:
· Current (mA) input and output range +/- 0 to 25 mA. · Voltage (V) output range 0 to +/- 30 VDC. 4. Put the Calibrator and calibration standard instrument in the calibration environment for a minimum of two hours. 5. Connect and energize the Calibrator and the calibration standard instrument using the cables supplied or equivalent high-quality cables. 6. Wait a few minutes for the Calibrator and other instruments to thermally stabilize. Consider changing the AUTO OFF setting to off to avoid disruption while waiting for readings to stabilize during calibration.
4.2 `ADJ’ (ADJUST) function
This function adjusts the Calibrator primary reading to the same value as the external calibration instrument when doing current source calibration. It is useful in current and voltage measure calibration when you use calibration values that are different to the preset values. The Calibrator will adjust itself to the external instrument value. For example, if you need to calibrate measurement at a value of 18 mA instead of the preset 19.5 mA, set your external instruments to 18 mA and use the `ADJ’ function to adjust the calibrator to set the Primary reading to 18 mA.
4.3 ADV (ADVANCED) button polarity function
You can use ADV button to change the sign (polarity) of the primary reading when using the ADJ (ADJUST) function while doing calibration.
4.4 Calibration Notes
Push the `MODE’ button or de-energize the Calibrator to escape the calibration setting at any time. If the calibrator shows an error code at any time during the calibration (see “Error Codes and Warnings” on page 50) then it is likely that the calibrated value is incorrect. Push the Enter button to accept the error and redo the calibration.

1. When you select this option the V and measure symbols will flash. Use the Navigation left and right buttons to move to the next calibration procedure or push the Enter button to accept. The screen will show the `SET’ symbol.
2. The Calibrator will take you through two ranges; one uses steps of the preset calibration values for the 20 V range, the second uses steps of the preset calibration values for the 30 V range. The secondary reading will show the preset calibration values. At each step, set your external calibrator to the preset value, or to your preferred chosen value of calibration.
3. The primary reading will show the measured values at each step. Wait a few minutes to make sure the measured value remains stable before you push Enter to accept. The Calibrator will accept the applied voltage as a calibrated value and readjust itself.
4. The ADJ symbol will flash to allow you to adjust the primary reading to the same value as the voltage from the calibrated instrument using the Navigation Pad up and down and left and right buttons. This is useful if using calibrated values that are different to the preset values. You do not need to use this adjustment if you are using the preset values.
5. Push the Enter button to accept.
6. At the last steps, the Calibrator will recommend values of 20 V and 30 V and show CHECK. Apply the recommended value and push Enter to accept.
