Megger’s PSI-700 Phase(Ǿ) Sequence Indicator 
Megger’s Multi-Volt PSI-700 is a rugged, lightweight instrument used to determine the phase sequence or phase rotation of a three-phase system that also detects and identifies an open phase.
The Model PSI-700 Phase Sequencer is simple to use. Simply connect the provided Color-Coded Clip Leads to the system and a lamp will instantly indicate either ABC clockwise rotation or CBA counter-clockwise rotation. Three lamps will illuminate to indicate that all phase voltages are present. When a phase is open, only one lamp will illuminate and identify the open phase. No additional external power is required for the PSI-700 Phase Sequence Indicator.
