motor shaft in the desired direction of

• If the CORRECT LED is lit, the
connections have been correctly
identified. Disconnect the test
instrument from the motor.
• If the INCORRECT LED is lit, switch
any two leads and repeat Step 4.
Note: The motor rotation function
relies on the residual magnetism
of the motor to indicate the
direction of motor rotation. If the
motor was not operated by the
manufacturer prior to shipment,
it will not have residual
magnetism and the 5123 will not
indicate the direction of motor
rotation.
Maintenance
Keep the test instrument clean and dry.
Replace leads that are worn or damaged.
