Application Notes (AC Amps)
When measuring AC 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 17, 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 cur-
rent 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.
