orientation of three phase power sources. The durable Extech signature orange and green housing is double
molded, and the Extech 480400 3-phase rotation tester comes complete with three wide-jawed color coded
alligator clip cables, all with a CE rating of CAT III-600V.
The Extech 480400 3-phase rotation tester has a large multi-line LCD display that is easy to read and
indicates phase orientation as well as phase sequence and whether each of the three phases is live or not.
The Extech 480400 3-phase rotation tester uses power from the power source being measured, so no batteries
are required.
