Application Notes
When measuring DC Voltage of a
battery, the most accurate reading can
be attained by testing the battery
under load. To accomplish this, follow
steps 1 through 4 shown on page 15
and the following (with the battery in
holder and device turned on):
• Connect the red test lead from the
meter to the positive (+) terminal
of the battery.
• Connect the black test lead to the
negative (-) terminal of the battery.
• Reconnect power to the circuit and
read the voltage on the 183.
3. Step by Step Procedures:
a. Measuring DC Volts
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.
WARNING!
Do not attempt to make a voltage measurement of
more than 1000V or of a voltage level that is
unknown.

Measurement Procedure:
1. Disconnect power to circuit to be measured.
2. Plug black test lead into the COM input jack.
3 Plug red test lead into the V input jack.
4. Set rotary switch to either the mV or V range,
depending on the voltage to be measured.
5. Connect test leads to circuit to be measured.
6. Reconnect power to circuit to be measured.
7. Read the voltage on the 183.
