The Martindale PSI4000 Three Phase Sequence Indicator enables non-contact measurement of phase rotation via inductive crocodile clips. Simply attach the crocodile clips around the conductors and the LEDs on the unit will give a clear indication of either clockwise or anti-clockwise phase rotation. It can be used to quickly identify three phase sequences for motor installations and repair.
The PSI4000 phase rotation tester can be used on both insulated and non-insulated conductors and also has a switch for increasing the brightness of the LEDs so that phase sequence can be clearly visible in all light conditions.
In addition the Martindale PSI4000 provides an audible indication of rotation and has a magnetised back that enables hands free testing by easily fixing to a metal surface for convience.
An "Auto Off" function activates after five minutes of non detectionto preserve battery life.
