Calibration Procedure For Isolated Modes; Isolated Voltage Monitoring Calibration - Ametek Sorensen XG Operation Manual

Calibration and Troubleshooting

Calibration Procedure for Isolated Modes

The main output and the non-isolated mode must be calibrated first.

Isolated Voltage Monitoring Calibration

Important: For maximum accuracy at a specific APG level, follow the
calibration procedure again but use the intended operating voltage level in steps
3 and 8.
To calibrate the isolated voltage monitoring:
1.
2.
3.
4.
5.
6.
7.
8.
9.
7-16
Disconnect the load and connect the voltmeter to the output.
Connect the voltmeter to the isolated voltage monitoring
output lines (J3.5 - J3.6).
Set the Voltage APG level to 4 V. The SCPI command is:
SYST:COMM:APR:LEV
Set the input source to local for voltage analog programming.
The SCPI command is:
SYST:REM:SOUR LOC
Set the main output voltage to 100% by sending the
command:
SOUR:VOLT <ModelVolt>
or use the rotary adjust/Enter control.
Turn the main output to On by pressing the OUTPUT
ENABLE Main button on the front panel or send the
command:
:OUTP ON
The OUTPUT ENABLE Main button will illuminate.
Enter the interactive calibration mode by sending the SCPI
command:
CAL:MON:ISOL
Press the terminal keys - or + to reduce or increase the
monitoring value. Adjust the monitoring value displayed on
the voltmeter that was setup in Step 1 to read as close as
possible to 4.000 V.
Press any key other than the + or - keys to exit from
interactive calibration mode.
