13. Enter the actual output current of the third calibration point:
CAL[n]:OUTP:CURR:FIVEPOINT 3
14. Program the output of the fourth calibration point by sending the following
command string from the computer:
CAL[n]:OUTP:CURR:DAC 45000
15. Let the output settle and measure the output current with the current shunt
and the high precision voltmeter; this is value 4.
16. Enter the actual output current of the fourth calibration point:
CAL[n]:OUTP:CURR:FIVEPOINT 4
17. Program the output of the fifth calibration point by sending the following
command string from the computer:
CAL[n]:OUTP:CURR:DAC 62250
18. Let the output settle and measure the output current with the current shunt
and the high precision voltmeter; this is value 5.
19. Enter the actual output current of the fifth calibration point:
CAL[n]:OUTP:CURR:FIVEPOINT 5
20. To review entered data for five–point current calibration, issue the following
query:
CAL[n]:OUTP:CURR:FIVEPOINT?
21. Program the supply to unlock the non-volatile memory for calibration value
storage:
CAL[n]:UNLOCK “6867”
22. Program the supply to store the calibration values in non-volatile memory:
CAL[n]:STORE
Allow 10 seconds for the non-volatile memory to be updated with the
new calibration values.
23. Program the supply to lock the non-volatile memory for calibration value
protection:
CAL[n]:LOCK
24. The output current calibration is complete. The unit may be turned off or other
calibration procedures may be performed.
