Sorensen SF Series IEEE 488.2 and SCPI Command Operation

6. Program the output of the second calibration point to approximately 85% of full scale

voltage by sending the following command string from the computer:

CAL:OUTP:CURR:DAC 55700

7. Let the output settle and measure the voltage with the meter.

8. Enter the actual voltage readback corresponding to the DAC value 5570 of the second

calibration point:

CAL:MEAS:VOLT:POINT 2 <voltage>

9. Reset the output voltage to 0 volts by programming the current to 0 amps.

CAL:OUTP:CURR:DAC 0

10. Program the DIA to calculate the voltage readback calibration gain and offset values:

CAL:MEAS:VOLT: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

14. The voltage readback calibration is complete. The unit may be turned OFF or other

calibration procedures may be performed.

4.4 Current Programming Calibration

STEP

DESCRIPTION

1. Program the overcurrent protection to maximum to prevent nuisance trips:

CAL:OUTP:CURR:PROT:DAC 65535

3. Program the output of the first calibration point to approximately 15% of full scale current

by sending the following command string from the computer:

CAL:OUTP:CURR:DAC 9830
