8. Press any key other than the + or – keys to exit from interactive
calibration mode.
Non-isolated Voltage Programming of Current Calibration
To calibrate the non-isolated voltage programming of current:
1. Short the main output with a shunt. Connect a multimeter to measure
the voltage across the shunt.
2. Connect the input voltage source to the non-isolated connector,
current programming (J1.10 - J1.7).
3. Set the Voltage APG level to 4 V. The SCPI command is:
SYST:COMM:APR:LEV:CURR 4
4. Set the input source voltage to 4.000 V.
5. Set the input source as Voltage Non-Isolated for Current. The SCPI
command is:
SYST:REM:SOUR:CURR AVOL
6. Turn the main output 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:OUTP:ANAL:CURR
8. Press the terminal keys – or + to reduce or increase the main output
current value. Adjust the main output current to 100%.
9. Press any key other than the + or – keys to exit from interactive
calibration mode.
Non-isolated Resistive Programming of Current Calibration
To calibrate the non-isolated resistive programming of current:
1. Short the main output with a shunt. Connect a multimeter to measure
the voltage across the shunt.
2. Connect the 4.000 k
Ω resistor to the non-isolated connector (APG -
J1), one terminal to resistive programming of current (J1.12) and
voltage programming of current (J1.10), and the other terminal to the
common (J1.7).
3. Set the resistive APG level to 4 k
Ω. The SCPI command is:
