This procedure calibrates the output voltage of the power supply. This is five-
point calibration procedure.
1. Connect the meter between the output and the output return lead.
2. Set the voltmeter to read the AC voltage.
3. Ensure that no load is connected to the output.
4. Issue clear and reset commands:
*CLS
*RST
5. Set the voltage range of the power supply to low
SOUR:VOLT:RANGE 0
6. Set the current to maximum limit
CAL:OUTP:CURR:COUNTS 4000
7. Turn the unit on
OUTP:STATE 1
8. Set the OVP supervisory to limit 20261
CAL:OUTP:VOLT:PROT:COUNTS 20261
9. Set the OCP supervisory to maximum limit.
CAL:OUTP:CURR:PROT:COUNTS 4000
10. Program the output voltage to 5% of the full scale voltage
CAL:OUTP:VOLT:COUNTS 965
11. 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
12. Program the output voltage to 27.5% of the full scale voltage
CAL:OUTP:VOLT:COUNTS 5307
