Using the Motor & Phase Rotation Meter
Determine the Rotary Field Direction
To determine the rotary field direction:
1.
Connect one end of the test leads to the motor & phase rotation
indicator. Make sure the L1, L2, and L3 test leads are connected to the
corresponding input jacks.
2.
Connect the test probes to the other end of the test leads.
