A critical instrument for checking & monitoring for the presence of OPEN PHASE and PHASE SEQUENCE in 3 Phase power applications. Testing and diagnosis results are communicated to the professional through designated LEDs and an audible buzzer simultaneously. The unit comes with interchangeable crock clips, but any type of probe can be used plus the unit contains a protective carrying case to keep your testing kit in excellent condition.
Testing is as easy as connecting the included well-insulated alligator clips of the unit to the three-phase circuit under test. The unit will indicate the presence of an open phase & phase sequence through the LEDs and buzzer.
