
The Count Inputs A and B are factory configured for falling edge triggered
(active low) operation in single edge count modes. The Counter Operating Mode
descriptions in the Input programming section reflect this logic. If an application
is better suited to use rising edge triggered (active high) operation, the Input
Logic for Input A and/or Input B can be changed by entering Code 55.

PAXI: CALIBRATION

The only item in the PAXI meter that can be calibrated

is the Analog Output. The Count A and B values are scaled


using the parameters in Module 1, Counter C value is scaled
using Module 5 and the Rate value is scaled using Module
4. If the meter appears to be indicating incorrectly or inaccurately, refer to the
Troubleshooting section.
When Analog Out recalibration is required (generally every 2 years), it
should be performed by qualified technicians using appropriate equipment.
Calibration does not change any user programmed parameters.
Calibration may be aborted by disconnecting power to the meter before
exiting Module 9. In this case, the existing calibration settings remain in effect.
Note: Allow a 30 minute warm-up period before staring calibration.
Analog Output Card Calibration
Before starting, verify that a precision meter with an accuracy of 0.05% or
better (voltmeter for voltage output and/or current meter for current output) is
connected and ready. Then perform the following procedure:
1. Use the arrow keys to display

3. Using the chart below, step through the five selections to be calibrated. At
each prompt, use the PAXI arrow keys to adjust the output so that the
external meter display matches the selection being calibrated. When the
external reading matches, or if the range is not being calibrated, press PAR.
