    Kewtech Kewprove 3 Proving Unit

    Small and portable proving unit which outputs 690V AC/DC, using just two contact points for AC and DC voltages. This unit will enable you to verify your voltage testers and detectors on site.

    Kewtech Kewprove 3 Key Features:

    • Essential for proving that circuits are not live when working on electrical circuits
    • Also proves the integrity of fuses in fused test leads
    • Continuity test for fused test leads using a 4mm connector
    • Magnetic base for convenience to mount on metal panels
    • Makes a perfect partner to the Kewtech KT1780 & Kewtech KT1790 Voltage Tester

    Lead Continuity Test

    If you are using fused test leads and your voltage detector does not indicate voltage when connected to your Kewprove, a fuse may have blown. The state of the fuse can be tested by plugging the test lead into the 4mm connector on the side and pressing the probe tip onto the metal stud on the front. A buzzer will sound indicating continuity.

    Important Information

    The KEWPROVE Proving unit puts out a hazardous voltage and must only be used by a qualified person and in accordance with the manufacturers instruction supplied with the unit.
