A non-invasive phase rotation indicator that uses bright LEDs positioned to emulate a rotating disc type indicator.
The PSI4000 carries out measurements via colour-coded non-contact clips, as opposed to probes or croc clips providing the safest way to conduct a phase sequence check.
The increased safety design of this phase rotation tester allows for use on both insulated and non-insulated conductors with a buzzer and bright LEDs giving a clear indication of clockwise or anti-clockwise phase rotation. Green LEDs indicate correct rotation while Red LEDs indicate incorrect or anti-clockwise rotation.
There is also an enhanced brightness button on the instrument face for clear indication in strong ambient light.
The Martindale PSI4000 is supplied with 4 x AA batteries, a soft carry case and a manual.
