2. Rotate the knob to select OCP and press [Enter].
3. Rotate the knob to select On and press [Enter] to enable the OCP
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.
Clear Over-Current Protection
When over-current protection occurs, the instrument responds as follows:
•
•
•
•
To clear the over-current and return to normal operation, firstly remove the
conditions that caused the protection fault. Press [Esc] key (or send the
command PROTection:CLEar) to clear the protection status. The "Over Current
Protect" displayed in front panel is cleared and the instrument exits OCP status.

5.3.2 Set Over-power Protection

Over-power protection function allows the user to enable the protection and set
a over-power limit (Level) and delay time (Delay). This function prevents the
output power from being higher than the limited output power and protects the
connected DUT so it this is not over-power and possibly damaged due to an
excessive power.
An over-power protection will occur if:
•
•
protection.
Instrument input is off;
The buzzer sounds;
The interface displays "Over Current Protect" and flashes;
Status register, the OC status bit is set to 1;
Enable OPP;
The output power value is greater than the set power protection point Level
and the period is greater than the set protection delay time Delay.
