        Major Tech MT310 | Socket ELCB Tester


        The MT310 Earth Leakage Tester is a compact, lightweight and easy to use socket and polarity and earth leakage tester that tests 3-wire 230V AC circuits and Earth Leakage Circuit Breakers. A unique feature is the AC Voltage indication on the LCD display. It also features a milli-amp (mA) trip setting with a separate test button. The unit can be set from 10mA, used for testing saturation and to eliminate nuisance tripping, to 35mA. The bright neon indication assists the user in confirming the wiring status of the circuit under test. Simply plug the MT310 into a wall socket and the results are clearly displayed. For additional safety, the MT310 is rated at CAT IV 300V and CAT III 600V.

        My original post was in error and I wish to apologise and correct it. The spec in the manual clearly states the display with change to 0L if the real voltage exceeds 245V and this is what my unit does. The slight problem is my display seems to be about 5V above actual so it can display up to about 249V before tapping out (at around ~244.5V. Major Tech were good enough to call me and explain the situation.
