2. Rotate the knob to select OPP and press [Enter] to confirm.
3. Rotate the knob to select On and press [Enter] to enable the function.
4. Rotate the knob to adjust the over-power limit Level and press [Enter] to
5. Rotate the knob to set the Delay time and press [Enter] to confirm.
6. Press [Esc] to exit.
Delay time
You can specify an OPP delay to prevent momentary output settings, DUT and
status changes from tripping the over-power protection. In most cases these
momentary conditions would not be considered an over-power protection fault,
and having an OPP condition disable the output when they occur would be a
nuisance. Specifying an OPP delay lets the OPP circuit ignore these
momentary changes during the specified delay period. Once the OPP delay
time has expired and the over-power condition persists, the output will shut
down.
Clear Over-Power Protection
When over-power protection occurs, the instrument responds as follows:
•
•
•
•
To clear the over-power 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 Power
Protect" displayed in front panel is cleared and the instrument exits OPP status.

Under-voltage protection function allows the user to enable the protection and
set a under-voltage limit (Level) and delay time (Delay).
An under-voltage protection will occur if:
•
•
confirm.
