19.3.2 Power Source Shuts Down
CONDITION POSSIBLE CAUSE, REMEDY
The power source shuts down when the EUT load is
applied If the companion power source shuts down when the
EUT load is applied, it is very likely that the power
source is being severely overloaded. Any severe
overload will cause the 1251RP or the 5001iX to
immediately program itself to zero volts
The power source shuts down immediately when it is
programmed to the test voltage Another possible cause of shutdown is a short circuit
in the EUT wiring or EUT load. Make sure neutral and
line wires don‟t form a short circuit.
19.3.3 Power Source Overload Light On
CONDITION POSSIBLE CAUSE, REMEDY
Overload light on power source is on When the overload light is on, the power source is
close to faulting or folding back the output voltage.
Adjust EUT loading if possible to keep power source
within its ratings.
19.3.4 No Signal To PC Interface
CONDITION POSSIBLE CAUSE, REMEDY
