The BZ701 detects 28 socket wiring fault conditions, which provides a fast and simple solution for checking that 13A sockets are wired correctly. The pattern of lit LEDs indicates the type of fault detected.
The BZ701 can also check the polarity of the incoming supply via the Blue Polarity Touchpad on the front of the unit (ideal for distribution companies). Correct incoming supply polarity is indicated by the flashing green LEDs accompanied by the continuous buzzer. Incorrect supply polarity will be indicated by the LED’s turning RED and a pulse tone on the buzzer.
The BZ701 has a standby mode, which activates after 10 minutes.
