Warm-up time
You can specify the warm-up time for UVP protection to make the instrument
not judge the under-voltage protection fault within the specified warm-up time.
Delay time
You can specify an UVP delay to prevent momentary output settings, DUT and
status changes from tripping the under-voltage protection. In most cases these
momentary conditions would not be considered an under-voltage protection
fault, and having an UVP condition disable the output when they occur would be
a nuisance. Specifying an UVP delay lets the UVP circuit ignore these
momentary changes during the specified delay period. Once the UVP delay
time has expired and the under-voltage condition persists, the output will shut
down.
Clear Under-voltage Protection
When under-voltage protection occurs, the instrument responds as follows:
•
Instrument output is off;
•
The buzzer sounds;
•
The interface displays “Under Voltage Protect” and flashes;
•
Status register, the UV status bit is set to 1;
To clear the under-voltage and return to normal operation, firstly remove the
conditions that caused the protection fault. Press

key (or send the
command PROTection:CLEar) to clear the protection status. The “Under
