Calibration Procedure
Calibration of 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
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
6. Power supply calculates and stores calibration constants.
