6.1 Set Over-Current Protection (OCP)
Users can enable the OCP function and set the protection limit Level and
protection delay time Delay. When the current (i.e., the Meter value) is greater
than this protection limit and the delay time is exceeded, the instrument will
enter the OCP state.
An over-current protection will occur if:
• Enable OCP;
• The load current value is greater than the set current protection point Level
and the period is greater than the set protection delay time Delay.
Enable OCP
1. Press [Shift]+[R-set](Protect) to enter the protection menu.
2. Rotate the knob to select OCP and press [Enter].
3. Rotate the knob to select On and press [Enter] to enable the OCP
protection.
4. Rotate the knob to select Level and adjust the value, press [Enter].
5. Rotate the knob to select Delay and adjust the value , press [Enter].
6. Press [Esc] to exit.
Delay time
You can specify an OCP delay to prevent momentary input settings, DUT and
status changes from tripping the over-current protection. In most cases these
momentary conditions would not be considered an over-current protection fault,
and having an OCP condition disable the input when they occur would be a
nuisance. Specifying an OCP delay lets the OCP circuit ignore these
momentary changes during the specified delay period. Once the OCP delay
time has expired and the over-current condition persists, the input will shut
down.
