Front Panel Calibration Procedure
TM-XDOP-01XN B–7
Front Panel Calibration Procedure
Calibration can also be done via remote control, using SCPI commands. See
“Remote Interface Calibration Procedure” on page B–11.
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. Enter output voltage calibration menu
Select Output V Cal from the calibration menu. Press ENTER.
You will be prompted to set up for output voltage calibration. Press ENTER
when ready.
3. Minimum calibration level
The power supply will automatically set the output voltage to 10%.
4. Enter voltage data
Enter the voltage output, read from the external DVM. Press ENTER
5. Maximum calibration level
The power supply will set the output voltage to 90%.
6. Enter voltage data
Enter the voltage output, read from the external DVM. Press ENTER.
7. Power supply calculates and stores calibration constants.
8. The menu will go to the Output Current Calibration menu.
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. Enter output current calibration menu
Select Output I Cal from the calibration menu. Press ENTER.
You will be prompted to set up for output current calibration. Press ENTER
when ready.
3. Minimum calibration level
The power supply will automatically set the output current to 10%.
4. Enter current data
Enter the current output, read from the external DVM via the shunt. Press
ENTER
