Protect Function
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 output will shut
down.
Clear Over-Current Protection
When over-current protection occurs, the instrument responds as follows:
• Instrument output is off;
• The buzzer sounds;
• The interface displays “Over Current Protect” and flashes;
• Status register, the OC status bit is set to 1;
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.
6.3 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:
• 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.
Enable OPP
1. Press [Shift]+[R-set](Protect) Protecto enter Protect menu interface.
2. Rotate the knob to select OPP and press [Enter] key to confirm.
3. rotate the knob to select On and press [Enter] key to confirm.
4. Rotate the knob to adjust the over-power limit Level and press [Enter] key to
confirm.
5. Rotate the knob to adjust the delay time Delay and press [Enter] key to
confirm.
6. Press [Esc] to exit.
