The Socket and See SOK36 advanced electronics initially performs its own internal self-check to confirm the unit is operating correctly. Next it will automatically check for correct wiring then perform a non-trip loop impedance check. Additional selectable functions are available to check the tripping function of 30mA RCD’s and also a mains Active / Neutral polarity check. Bright LED's outperform fragile old style neon's Logical 'Green for Good' LED Indication New Circuitry avoids tripping RCD's when testing wiring Continuous audible tone gives positive good wiring indication Strong warbling tone gives clear warning of faulty wiring Advanced electronics include a quad comparator to give clear indication even on noisey circuits New patented 'Fault Locate' electronics gives clearest indication yet of good plus 17 wiring fault conditions Built-in self-check at start of testing gives confidence of correct operation at all times The first socket tester to also test true earth loop impendance Easy colour LED read out system indicates earth loop result as
