Operation and Application
3. Rotate the knob to adjust the OVP(rms) point and press [Enter] key to
confirm.
4. Press [Esc] to exit the protection menu setting.
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
confirm.
4. Press [Esc] to exit the protection menu setting.
