PLEASE NOTE:
Recalibration should only be performed if necessary and only by qualified technicians using appropriate calibration equipment.
In some cases, the PAXD unit numbers below will have a B suffix. This just means blank, no logo on front bezel.
APPLICABLE PRODUCTS
PAXD0000, PAXD0010, PAXD0100, PAXD0110
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.

PAXD input wiring
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. Press PAR.
3. When the zero range limit appears on the display, apply the appropriate:
- Voltage ranges: dead short applied
- Current ranges: open circuit
- Resistance ranges: dead short with current source connected
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 ranges: top range value applied (The 300 V range is the exception. It is calibrated with a 100 V signal.)
- Current ranges: top range value
- Resistance ranges: top range value (The ohms calibration requires connection of the internal current source through a resistance substitution device and the proper voltage range selection.)
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.
