10. Enter the actual output current of the second calibration point:

CAL:OUTP:CURR:FIVEPOINT 2 <value 2>

11. Program the output of the third calibration point by sending the following

command string from the computer:

CAL:OUTP:CURR:DAC 32000

12. Let the output settle and measure the output current with the current shunt

and the high precision voltmeter; this is value 3.

13. Enter the actual output current of the third calibration point:

CAL:OUTP:CURR:FIVEPOINT 3 <value 3>

14. Program the output of the fourth calibration point by sending the following

command string from the computer:

CAL: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:OUTP:CURR:FIVEPOINT 4 <value 4>

17. Program the output of the fifth calibration point by sending the following

command string from the computer:

CAL: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:OUTP:CURR:FIVEPOINT 5 <value 5>

20. To review entered data for five–point current calibration, issue the following

query:

CAL:OUTP:CURR:FIVEPOINT?

21. Program the supply to unlock the non-volatile memory for calibration value

storage:

CAL:UNLOCK “6867”

22. Program the supply to store the calibration values in non-volatile memory:

CAL:STORE

Allow 15 seconds for the non-volatile memory to be updated with the

new calibration values.
