Over Voltage Protection (OVP) Calibration

Over Voltage Protection (OVP) Calibration

We recommend that you perform OVP calibration every six months. Connecting a digital voltmeter as in “Voltage Calibration Setup” is optional.

1.Disconnect all loads from the power supply.

2.Ensure that jumper J2 on the interface PCB is CLOSED to enable remote OVP calibration (Jumper J2 is closed at the factory). See Figure 2.3 RS-232 Interface PCB, p. 18 for the location on the PCB of jumper J2.

3.Activate calibration mode by sending command CMODE ON or CMODE 1 to the power supply.

4.Send the command OVCAL to the power supply. The ADDR LED will light during OVP calibration. Calibration is complete when the ADDR LED turns off. This may take a few minutes.

5.Use the OVSET, OVSET?, and VSET commands to trip the OVP level, confirming that the calibration was successful. When you trip the OVP level, the red OVP LED will light and the voltage will drop to zero. Send the command RST to clear the OVP condition. Refer to the OVP program accuracy specification in Section 1.

6.Turn off calibration mode by sending the command CMODE OFF or CMODE 0 to the power supply.
