As well as providing all of the features needed for the safe, convenient and efficient testing of low voltage electrical installations, the Megger MFT1711 multifunction tester offers valuable extra features that were previously only available on more expensive instruments. These include a maximum Zs function, which makes it unnecessary to remember individual Zs readings when testing an installation, automatic RCD testing and true RMS voltage measurement.

The MFT1711 can test RCDs with sensitivities from 10 mA to 500 mA, including programmable types. Like all instruments in the range, it provides three options for loop testing – two-wire no trip, three-wire no trip and high current – which means that the fastest and most convenient method can be used in every situation. It also features fast-response continuity testing.

The unique modern styling allows it to be operated while stood on the floor, a ladder-shelf or platform, hung around the neck or handheld. Dual TEST and LOCK buttons - one pair at each end - makes the testers easy to operate left or right handed.
