PLEASE NOTE:
Recalibration should only be performed if necessary and only by qualified technicians using appropriate calibration equipment.
In some cases, if the PAX unit listed below has a B suffix. It just means blank, no logo on the front bezel.

PRE-REQUISITES
- For all calibrations, allow the panel meter to warm up for 30 minutes minimum and follow the manufacturer's warm-up recommendations for the calibration source and measuring device.
- Calibration of this meter requires a signal source with accuracy of 0.01% or better and an external meter with an accuracy of 0.005% or better.

- Calibrating the unit to correct when the panel meter appears to be indicating incorrectly or inaccurately, even after troubleshooting with the factory
Input signal wiring diagram
DSP and PAR can be chosen to exit the calibration mode without any changes taking place.
Perform the following procedure:
1. Use the arrow keys to display CODE 48 IN MENU 9-FCS and press PAR.
2. Choose the range to be calibrated by using the arrow keys and press PAR. (CAL NO and PAR can be chosen to exit the calibration mode without any changes taking place.) Select CAL OUT if calibrating an optional output card. Select 0.02 A if calibrating the 4-20 mA input or 10 volts if calibrating the 0-10 Vdc input. Press PAR.
3. When the zero range limit appears on the display, apply the appropriate:
-Voltage range: dead short applied
- Current range: open circuit
4. Press PAR and ----- will appear on the display for about 10 seconds.
5. When the top range limit appears on the display, apply the appropriate:
- Voltage range: 10 VDC
- Current range: 20 mADC
6. Press PAR and ----- will appear on the display for about 10 seconds.
7. When CAL NO appears, press PAR twice.
8. If the meter is not field scaled, then the input display should match the value of the input signal.
9. Repeat the above procedure for each input range to be calibrated.
