Model EPM3 is two measurement devices in one unit that provides three functions - phase sequence identification, open phase condition and motor rotation indication.

When making these types of high voltage measurements, you want to trust your equipment. The EPM3 meets the new tough 2005 CE standards for safety. One half of the EPM3 measures the phase sequence of a 3-wire system using the power of the system under test. Using lamp indicators, it will indicate the 3-phase sequence or it will indicate an open phase situation. The other half of the EPM3 measures 3-phase motor rotation on an unpowered motor using the EPM3's internal 9 volt battery. The unit will indicate whether the motor shaft has clockwise or counter-clockwise rotation. Both sections of the EPM3 are safety protected to CAT III 600V.

Chose the EPM3 for those times you are in a CAT III energy environment.
