Application Notes (Resistance)
32
When measuring resistance of a motor, make
sure the power is disconnected prior to testing.
Set up meter following steps under
“Measurement Procedure” on page 16, and
proceed with the following:
•
•
Connect the red test lead to one power
Connect the red test lead to the frame of
input line of the motor and the black test
lead to the other power input line of the
motor. In most applications if the reading
is OFL, the motor winding is open.
the motor and the black test lead to the
winding. In most applications if a reading
of 0 Ohms is displayed, the winding is
shorted to the motor frame (ground).
