    Extech 480403 Phase Rotation Tester

    The Extech 480403 Phase Rotation Tester is a useful instrument that is capable of showing the phase rotation of a motor, even without being physically connected. When connected, it is also capable of checking if each phase is live and it is ideal for making sure that incorrect wiring does not cause any damage.

    The tester has a 40V to 600V AC testing range on voltages of a frequency between 2 to 400Hz for testing phase orientation. The LED interface indicates clockwise or anti-clockwise rotation as well as the status of each of the three phases.

    The Extech 480403 is a lightweight model and is protected by double-moulded durable housing. It comes supplied with three test leads and a set of wide-jaw crocodile clips as well as a pouch case and 9V battery.
