4. Let the output settle and measure the current with the current shunt and the meter.
5. Enter the actual output current corresponding to the DAC value 7830 of the first
calibration point:
CAL:OUTP:CURR:POINT 1
CAL:MEAS:CURR:POINT 1
6. Program the output of the second calibration point to approximately 85% of full scale
current by sending the following command string from the computer:
CAL:OUTP:CURR:DAC 55700
7. Let the output settle and measure the current with the current shunt and the meter.
8. Enter the actual output current corresponding to the DAC value 55700 of the second
calibration point:
CAL:OUTP:CURR:POINT 2
CAL:MEAS:CURR:POINT 2
9. Reset the output current to 0 amps.
CAL:OUTP:CURR:DAC 0
10. Program the DIA to calculate the output current and current measurement calibration
gain and offset values:
CAL:OUTP:CURR:CALC
CAL:MEAS:CURR:CALC
11. Program the DIA to unlock the non-volatile memory for calibration value storage:
CAL:UNLOCK “6867”
12. Program the DIA to store the calibration values in non-volatile memory:
CAL:STORE
13. Program the DIA to lock the non-volatile memory for calibration value protection
CAL:LOCK
The output current and current measurement calibrations are completed at the same time.
The unit may be turned OFF or other calibration procedures may be performed.
