Remote Interface Calibration Procedure
TM-XDOP-01XN B–11
Remote Interface Calibration Procedure
Calibration can also be done via front panel. See “Front Panel Calibration
Procedure” on page B–7.
Calibration of voltage programming and readback are combined in a single
procedure.
Output Voltage
1. Set the load to open circuit. Attach a DVM across the output terminals.
2. Minimum calibration level
Set the output voltage to 10% by sending the command:
CAL:OUTP:VOLT:LEV MIN
3. Enter voltage data
Enter the voltage read from the external DVM.
CAL:OUTP:VOLT:DATA <voltage>
4. Maximum calibration level
Set the output voltage to 90% by sending the command:
CAL:OUTP:VOLT:LEV MAX
5. Enter voltage data
Enter the voltage read from the external DVM.
CAL:OUTP:VOLT:DATA <voltage>
6. Power supply calculates and stores calibration constants.
Output Current
1. Set the power supply and load operate at full output. You must ensure the
power supply is operating in current mode during current calibration. Place a
shunt on the load line so that you can measure the current. Attach a DVM
across the shunt
2. Minimum calibration level
Set the output current to 10% by sending the command:
CAL:OUTP:CURR:LEV MIN
3. Enter current data
Enter the current read from the external DVM via the shunt.
CAL:OUTP:CURR:DATA <current>
4. Maximum calibration level
Set the output current to 90% by sending the command:
CAL:OUTP:CURR:LEV MAX
