AC Power Testing Procedure
Step Actions and Questions
1 1. Disconnect the AC power cord from the wall outlet.
for
[115
VAC]
2. Measure the AC voltage between AC Line and
Neutral, between AC Line and Ground, and between
AC Neutral and Ground.
3. The voltage between Line and Neutral and between
Line and Ground should range from 90 to 140 VAC
and the voltage between Neutral and Ground should
be less than 3 VAC.
Is the AC voltage within specification?
1 1. Disconnect the AC power cord from the wall outlet.
for
[220
VAC]
2. Measure the AC voltage between Line and Neutral,
between AC Line and Earth/Ground, and between
Neutral and Earth/Ground.
3. The voltage between Line and Neutral and between
Line and Earth/Ground should range from 198 to 264
VAC and the voltage between Neutral and Ground
should be less than 3 VAC.
Is the AC line voltage within specification?

Is the AC line voltage within specification?
2 1. Check the continuity through all connections of the
power cord.
2. The measurement should be less than 10 ohms for
each connection.
Does continuity test per specification?
