The Fluke 9040 is effective for measuring phase rotation in all areas where three phase supplies are used to feed motors, drives and electrical systems.
 
The Fluke 9040 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 700 V) and frequency range suitable for commercial and industrial applications.
 
The included test probes have a variable clamping range for safe contact, also in industrial sockets. 3 phase indicationIndication of phase rotationClear LCD displayNo battery required
