Abstract:
This document describes calibrating the optional analog output card for PAX series Panel Meters.
Products:
PAXCDL10
Use Case: PAXCDL10 Calibration
Calibrating the unit to correct when the PAXCDL10 option card appears to be indicating an incorrect or inaccurate output, even after troubleshooting with the factory.
WARNING!
Entering calibration mode may void the factory warranty.
The PAXCDL10 output card has been fully calibrated at the factory. Scaling to convert the input signal to a desired output value is performed in Configuration Module 8, Output Parameters. If the output 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 an external meter with an accuracy of 0.005% or better.
ANALOG OUTPUT CARD CALIBRATION
Before starting, verify that the precision voltmeter (voltage output) or current meter (current output) is connected and ready. Perform the following procedure:
1. Use the arrow keys to access menu 9-FCS CODE 48 and press PAR.
2. Use the arrow keys to choose OUT and press PAR.
3. Using the chart below, step through the five selections to be calibrated. At each prompt, use the PAX arrow keys to adjust the external meter display to match the selection being calibrated. When the external reading matches, or if this range is not being calibrated, press PAR.
4. You only need to calibrate the output being used for the application.
SELECTION EXTERNAL METER ACTION
0.00 0.00 Adjust if necessary, press PAR
4.00 4.00 Adjust if necessary, press PAR
20.00 20.00 Adjust if necessary, press PAR
0.00 0.00 Adjust if necessary, press PAR
10.00 10.00 Adjust if necessary, press PAR
5. When CAL NO appears remove the external meters and press PAR twice to exit.
