Isolated Current 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 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).
3. Set the current APG level to 4 V. The SCPI command is:
SYST:COMM:APR:LEV:CURR 4
4. Set the input source to local for voltage analog programming.
the SCPI command is:
SYST:REM:SOUR:CURR LOC
5. Set the main output voltage to 100% by sending the
command:
SOUR:VOLT <ModelVolt>
or use the rotary Adjust/Enter control.
6. 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.
7. Enter the interactive calibration mode by sending the SCPI
command:
CAL:MON:CURR:ISOL
8. Press the terminal keys - or + to reduce or increase the
monitoring value. Adjust the monitoring value displayed on
the voltmeter that was set up 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.
