This procedure calibrates the hall gain sensor of the power supply for the 5KHz
AC unit only. This is seven-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.
5. Issue clear and reset commands:
*CLS
*RST
6. Set the voltage range of the power supply to high
SOUR:VOLT:RANGE 1
7. Turn the unit on
OUTP:STATE 1
8. Set the hall calibration data to the default value
CAL:OUTP:FREQ:CURR:DEFAULT
9. Set the output voltage to 240 Volts
SOUR:VOLT 240
10. Set the output current to 3.15 Amps
SOUR:CURR 3.15
11. Turn on the resistive load and adjust the load until the output voltage is 230 Volts,
this will ensure that the AC supply is in Constant Current Mode.
12. Set the output frequency to 60Hz
SOUR:FREQ 60
13. Wait for AC current to stabilize. Measure the output current using the AC meter.
Enter the measured current using following command
CAL:OUTP:FREQ:CURR1
