1. Trend/event capture
Phase sequence indication (direction of field rotation) in the power network with rated phase-to-phase voltage (120…690 V) AC by LED signalization.
Operation in the power network with frequency range 10…70 Hz.
Indication of the voltage presence in the particular phases by neon lamps signalization.
Power supply from the tested network (continuous operation to 15 minutes for max. voltage).
Protection against faulty indication of field rotation.
