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   and press

PAR.

2.  is displayed. Use the arrow keys to select  and press

PAR.

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.

4. When   appears, press

PAR twice and remove the external meters.

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.

Shaded areas are model dependent.

INPUT A AND B LOGIC SELECTION

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.





Selecting  sets the Input A logic to rising edge triggered (active high)

operation. Be advised that all references to Input A falling edge and Input A

rising edge will be reversed for the Counter Operating Mode descriptions.





Selecting  sets the Input B logic to rising edge triggered (active high)

operation. Be advised that all references to Input B falling edge and Input B

rising edge will be reversed for the Counter Operating Mode descriptions.
