Clear OVP(rms) status

When over-voltage protection occurs, the instrument responds as follows:

• The instrument output is turned off, and other keys (except the [Esc] key)

are locked.

• The buzzer sounds intermittently three times: one long beep and two short

beeps.

• The interface displays “OVPrms Occurred!!”;

• Status register, the OVPrms status bit is set to 1.

To clear the over-voltage and return to normal operation, firstly remove the con-

ditions that caused the protection fault. Press [Esc] key (or send the command

PROTect:CLEar) to clear the protection status. The “OVPrms Occurred!!” dis-

played in front panel is cleared and the instrument exits OVP(rms) status.

4.10.2 Set the Over-Voltage Protection (peak)

The user can set the over-voltage protection point for the over-voltage protec-

tion (peak) function. When the output voltage reaches the over-voltage protec-

tion point, the over-voltage protection (peak) will turn off the output. The

function is mainly used to protect the DUT connected during test to prevent it

from damage due to over-voltage. The OVP (peak) function is always enabled.

Set the OVP(peak) point

1. Press the composite keys [Shift] + [F-set](Protect) to enter Protect menu

interface.

2. Rotate the knob to select OVP(peak) and press [Enter] key to confirm.

3. Rotate the knob to adjust the OVP(peak) point and press [Enter] key to
