Isolated Voltage Programming of Voltage Calibration
Important: For maximum accuracy at a specific APG level, follow the
calibration procedure again but use the intended operating voltage level in step
3.
To calibrate the isolated voltage programming of voltage:
1. Disconnect the load and connect the voltmeter to the output.
2. Connect the input voltage source to the Isolated connector
(J3.3 and 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 voltage to 4.000 V.
5. Set the input source as Voltage Isolated for Voltage. The
SCPI command is:
SYST:REM:SOUR AVOL
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 :OUTP:ANAL:ISOL
8. Press on the terminal keys - or + to reduce or increase the
main output voltage value. Adjust the main output voltage to
100%.
9. Press any key other than the + or - keys to exit from
interactive calibration mode.
