The following procedure calibrates the output voltage of the power supply. This is
five- point calibration procedure. Connect the meter between the output and the
output return lead. Set the voltmeter to read the AC voltage.

1. Ensure that no load is connected to the output.

2. Issue clear and reset commands:

*CLS
*RST

3. Set the voltage range of the power supply to high

SOUR:VOLT:RANGE 1

4. Set the current to maximum limit

CAL:OUTP:CURR:COUNTS 4000

5. Turn the unit on

OUTP:STATE 1

6. Set the OVP supervisory to limit 20261

CAL:OUTP:VOLT:PROT:COUNTS 20261

7. Set the OCP supervisory to maximum limit.

CAL:OUTP:CURR:PROT:COUNTS 4000

8. Program the output voltage to 5% of the full scale voltage

CAL:OUTP:VOLT:COUNTS 965

9. Wait for AC voltage to stabilize. Measure the output voltage using the AC

voltmeter. Enter the measured voltage using following command

CAL:OUTP:VOLT:FIVEPOINT1

10. Program the output voltage to 27.5% of the full scale voltage

CAL:OUTP:VOLT:COUNTS 5307

11. Wait for AC voltage to stabilize. Measure the output voltage using the AC

voltmeter. Enter the measured voltage using following command
