PRM-6 Phase Sequence and Motor Rotation Tester

The PRM-6 Phase Sequence and Motor Rotation Tester can test the motor rotation of 3-phase
systems and verify 3-phase receptacle wiring and phase sequencing with test leads. An additional
advanced feature is wireless motor rotation detection, which senses motor rotation direction
without use of test leads, particularly useful for fast-running motors when the motor rotation
cannot be visually determined or when the drive shaft is not visible. The PRM-6 is an essential
tool for motor rotation and phase sequence testing in commercial and industrial environments on
electrical systems up to 700 V.

• 3-phase wire sequence indication

• Synchronous or asynchronous motor rotation
direction

• Error displays (missing phase, one input
connected to neutral or PE)

• Non-contact, wireless motor rotation detection
on running motors

• Indicates motor rotation of disconnected motors
when spinning the shaft by hand or other
means
