PAXP Input Calibration
Abstract:
This document describes calibrating the inputs of PAXPxxxx Panel Meters.
Products:
PAXP0000, PAXP0010, PAXP0100, PAXP0110
Use Case: PAXP Calibration
Calibrating the unit to correct when the controller appears to be indicating incorrectly or inaccurately, even after troubleshooting with the factory.
WARNING!
Entering calibration mode may void the factory warranty.
The controller has been fully calibrated at the factory. Scaling to convert the input signal to a desired display value is performed in Configuration Module 1, Input Parameters. If the controller appears to be indicating incorrectly or inaccurately, refer to Troubleshooting before attempting to calibrate the controller.
Recalibration should only be performed if necessary and only by qualified technicians using appropriate calibration equipment.
NOTE 1: Module 1 program parameter may be changed during calibration. Entering CodE 48 will require that Input Parameters (Module 1) be verified after calibration is complete.
NOTE 2: For all calibrations, allow the controller to warm up for 30 minutes minimum and follow the manufacturer’s warm-up recommendations for the calibration source or measuring device
WARNING: Calibration of this meter requires a signal source with an accuracy of 0.01% or better and an external meter with an accuracy of 0.005% or better.
Before starting, verify that the precision signal source is connected to the correct terminals and ready. Allow a 30 minute warm-up period before calibrating the meter.
DISP 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.
