Elma DT 902 Motor rotation indicator

Elma DT 902 is a new handy tool for anyone working with supply, service and control of three-phase motors. The instrument has three functions: - Shows directly before connection to an electrical current engine, how it should be connected, to rotate properly. - Phase Sequence Test for displaying rotating field and phase indication on three-phase electrical distribution. - Rotary indicator shows, without electrical contact, rotation of a motor in operation.
