# MESSAGES DESCRIPTION PROBABLE CAUSE APPROPRIATE ACTION
___________________________________________________________________________________________________________
0 VOLTAGE
OVERLOAD
Too much current is being
drawn from the voltage
output. The flashing
OVERLOAD light is
illuminated.
1. Voltage cable connectors
shorted.
2. Improper meter connections.
3. Meter impedance too low.
4. Selected voltage too high.
1. Check for proper operation
with voltage cable is
connected from PMC. If Error
persists, an internal fault
exists.
2. Check voltage cable for
isolation between banana
connections.
3. Check meter for proper input
impedance.
0 CURRENT
OVERLOAD
The voltage at the current
output went beyond the
compliance limit attempting
to reach the requested
current. The flashing
OVERLOAD light is
illuminated.
1. Current cable connections
improper.
2. Meter impedance too high.
3. Selected current too high.
1. Check the current cable
impedance.
2. Using tested current cable,
check for proper operation
with cable ends shorted. If
error persists, an internal fault
exists.
3. Check for proper meter
connections.
4. Check meter for proper input
impedance.
