Application Notes
When measuring DC Amps of a motor there
are two types of measurements that can be
made, running current and in-rush or start-up
current. Start-up current will usually be much
higher than running current.
Set up the meter following the steps under
“Measurement Procedure” on page 18, and
then proceed with the following:
•
Clamp the meter around a single wire
and reconnect power to the device.
Read the current displayed on the meter.
This is the running current of the motor.
•
Disconnect power to the motor and put
the meter in PEAK HOLD mode.
Reconnect the power and read
the current displayed on the
meter. This is the in-rush or
start-up current
of the motor.

Application Notes
When measuring DC Voltage of a bat-
tery, 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 296.
