    Note ● When testing 3P outlet, do not connect multiple KEW 4506 at the same time. If testing outlets wired from the same transformer simultaneously, correct judgement result may not be obtained. ● On the following wiring systems, resistance value isn’t used for judgment.

  • Page 15: Socket Test Procedures

    When testing wiring systems such as TT system, which has high total earth resistance (resistance between N-E is 2 Ω or higher), you just need KEW 4506 and measure resistances of earth pole (E) and neutral wire (N) to check N and E are wired properly.
