FUNCTION
CAUTION
Do not attempt to make a voltage measurement if a test
lead is plugged in the A or mA input jack. Instrument
damage and/or personal injury may result.
Do not attempt to make a voltage measurement of more
than 1000V or of voltage level that is unknown.
Measurement Procedure:
1. Disconnect power to circuit to be measured.
2. Plug black test lead into the

Procedure” on page 13. 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.
Application Notes
Disconnect power from the terminal
block, find the fuse or circuit breaker
that controls the block and turn it
off.
Set up the meter following the
steps under “Measurement
