Over Voltage Protection Calibration
To calibrate the over voltage protection:
1. Turn on the power supply.
2. Select the VAP mode to be Off.
3. Set the voltage set point to be 90% of the model voltage and the
current to be 10% of the model current.
4. Turn on the main power output.
5. Execute the OVP calibration SCPI command:
:CAL:PROT <output value set in step 3>
6. The power supply will enter into self-calibration mode. The output
voltage display reads blink OVP CAL. After several seconds, the
calibration will complete and the display will return to normal
operation with output off.
Calibration of the power supply is complete.
The SCPI command (s) for these instructions are:
[:]CALibration[:VOLTage]:PROTection[:OVER]
{<expected output value>}
Important:
The Voltage Calibration must be done before performing this
procedure. If this is not done the OVP calibration will be inaccurate.
Important:
The output (main) voltage must be precalibrated.
