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
5. Enter current data
Enter the current read from the shunt via the external DVM.
CAL:OUTP:CURR:DATA <current>
6. Power supply calculates and stores calibration constants.
