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.
