URRENT
This procedure calibrates the output current of the power supply. This is a five-
point calibration procedure.
1. Close the switch between the power supply and the resistive load.
2. Connect the meter between the output and adjustable resistive load.
3. Set the voltmeter to read the AC current.
4. Ensure that load is connected to the output. Load setting should select a range
for 0 to 10Amps at 125Volt AC
5. Issue clear and reset commands:
6. Set the voltage range of the power supply to low:
7. Set the OVP supervisory to limit 20261:
8. Set the OCP supervisory to maximum limit:
9. Turn the unit on:
10. Set the output voltage to 100 Volts:
11. Program the output current to 5% of the full scale current:
12. Wait for AC current to stabilize. Measure the output current using the AC meter.
Enter the measured current:
13. Program the output current to 27.5% of the full scale current:
