Calibration Procedure for Isolated Modes
The main output and the non-isolated mode must be calibrated first.
Isolated Voltage Monitoring Calibration
To calibrate the isolated voltage monitoring:
1. Disconnect the load and connect the voltmeter to the output.
2. Connect the voltmeter to the isolated voltage monitoring output lines
(J3.5 - J3.6).
3. Set the Voltage APG level to 4 V. The SCPI command is:
SYST:COMM:APR:LEV 4
4. Set the input source to local for voltage analog programming. The
SCPI command is:
SYST:REM:SOUR:ISOL LOC
5. Set the main output voltage to 100% by sending the command:
SOUR:VOLT <ModelVolt>
or use the Rotary knob/Enter button.
6. Turn the main output to On by pressing the OUTPUT ON/OFF button
on the front panel or send the command:
:OUTP ON
The OUTPUT ON/OFF button will illuminate.
7. Enter the interactive calibration mode by sending the SCPI command:
CAL:MON:ISOL
8. 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.
9. Press any key other than the + or – keys to exit from interactive
calibration mode.
Isolated Current Monitoring Calibration
To calibrate the isolated current monitoring:
1. Short the main output with a shunt. Connect a multimeter to measure
the voltage across the shunt.
2. Connect the voltmeter to the Isolated monitoring output lines (J3.10
and J3.6).
