Just Do Not Need To Guess Any Further for Phase / Motor Rotation Measurements

The DT-901 is effective for measuring phase rotation in all areas where three-phase supplies are used to feed motors, drives and electrical systems. The DT-901 is a rotary field indicator and can provide clear indication of the 3 phase via an LCD display and the phase rotation direction to determine correct connections. It allows rapid determination of phase sequence and has a voltage (up to 690 V) and frequency range suitable for commercial and industrial applications (15 to 400Hz). Test probes supplied with the instrument have a variable clamping range for safe contact, especially in industrial sockets.
