Non-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 steps
3 and 4.
To calibrate the non-isolated voltage programming of voltage:
1.
Disconnect the load and connect the voltmeter to the output.
2.
Connect the input voltage source to the non-isolated connector, voltage
programming (J1.9 - J1.7).
3.
Set the Voltage APG level to 4 V. Send the SCPI command:
SYST:COMM:APR:LEV 4
4.
Set input source voltage to 4.000 V.
5.
Set the input source as Voltage Non-Isolated for Voltage Programming. 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
8.
Press the terminal keys - or + to reduce or increase the main output voltage value.
Adjust the main output voltage to 100%, measured on the external voltmeter on
the output.
9.
Press any key other than the + or - keys to exit from interactive calibration mode.
