F. Application Notes (AC Volts)
Disconnect power from the
terminal block, find the fuse
or circuit breaker that con-
trols the block and turn it
off.
Set up the meter following
the steps under
“Measurement Procedure”
on page 15. Then proceed with
the following:
•Connect the red test lead to
the hot side of the block and
the black lead to the neutral
side of the block. Reconnect
power to the block and read
the voltage on the meter. The
reading should be approximately 110V to
130V.
• Disconnect power from the block and move
the red wire to ground. Reconnect power to
the block and read the voltage on the meter.
Typically less than 20V should exist from
neutral to ground. If 110V or above exists,
the block may be wired incorrectly.
