Set Over-Voltage Protection - ITech IT-M3100D Series User Manual

4.4.2 Set Over-Voltage Protection

Over-voltage protection function allows the user to enable the protection and
set a over-voltage limit (Level) and delay time (Delay). This function prevents
the output voltage from being higher than the limited output voltage and protects
the connected DUT so it this is not over-voltage and possibly damaged due to
an excessive voltage.
An over-voltage protection will occur if:
•
•
When over-voltage protection occurs, the instrument responds as follows:
•

Enable OVP
1. Press [Shift]+[Esc] (Protect) to enter Protect menu interface.
2. Use left and right keys or rotate the knob to select OVP and press [Enter]
3. Use left and right keys or rotate the knob to select On and press [Enter] key
4. Rotate the knob to adjust the over-voltage limit Level and press [Enter] key
5. Rotate the knob to adjust the delay time Delay and press [Enter] key to
6. Press [Esc] to exit the protection menu setting.
Enable OVP;
The output voltage value is greater than the set voltage protection point
Level and the period is greater than the set protection delay time Delay.
Delay time Delay — You can specify an OVP delay to prevent momentary
output settings, DUT and status changes from tripping the over-voltage pro-
tection. In most cases these momentary conditions would not be considered
an over-voltage protection fault, and having an OVP condition disable the
output when they occur would be a nuisance. Specifying an OVP delay lets
the OVP circuit ignore these momentary changes during the specified delay
period. Once the OVP delay time has expired and the over-voltage condition
persists, the output will shut down.
Instrument output is off;
The buzzer sounds;
The interface displays "Over Voltage Protect" and flashes;
Status register, the OV status bit is set to 1.
