New to the electrical installation industry, or looking for a robust, easy-to-use and low cost unit for your tests? Megger's 1711 is an ideal starting point for any electrical installer, combining together all the basic tests you need with intuitive, lightweight and safe design.

The next generation, upgraded version of Megger's highly popular 1710 multifunction tester, the 1711 includes a number of new features designed to make electrical installation testing easier than ever before. You can still expect the same Megger quality you'd expect from previous models in the series, and that's exactly why countless installers trust Megger multifunction testers as their tool of choice every single day.

The Megger 1711 multifunction tester is suitable for use on domestic, commercial and industrial fixed wire low voltage installations in accordance with the requirements of BS7671.

Megger MFT1711 Multifunction Tester In UseWhat's New for the 1711?

As the new version of the 1710, the 1711 comes with a selection of brand new features for an entry-level electrical installation testing tool.

These include:

  • Expanded Insulation Resistance Test Voltage Range to 1kV (1000V) - in the past, the 1000V test voltage was only found on higher-end models in the series
  • Max Zs Display - testing final ring circuits? It's quick and easy thanks to the new, large-size Max Zs display on the Megger 1711. There's no need to write down Zs values as you check every socket on a ring; the 1711 will automatically identify and store the highest value you measure
  • True RMS Voltage Measurements - rest assured that your AC voltage measurements are as accurate as possible, even on irregular waveforms, thanks to true RMS included as standard
  • Automatic RCD Testing - take the hassle out of testing RCDs as the Megger 1711 will do it all for you complete with 10mA RCD and programmable (VAR) RCD compatibility. There's no need to press the test button - tests will start automatically when you apply probes to the circuit (this also works for continuity/loop testing)

Wide Range of Electrical Installation Testing Procedures

When you're using the Megger 1711 multifunction tester, you'll see just how much easier your electrical testing can truly become.

The 1711 gives you quick, easy access to all of your testing procedures via colour-coded rotary dials and dual testing buttons on either side of the MFT make it easy to activate a test, regardless of where you're working.

You can expect all of the following measurement procedures when using the MFT1711:

  • Continuity/Resistance - complete with 200mA range and automatic continuity test start
  • Insulation Resistance - including test voltage display, full protection against live circuits and selectable test voltages of 1kV (1000V), 500V and 250V
  • Earth Loop Impedance - 2-wire no trip test (L-PE), 3 wire no trip test (L-PE), 2 wire high current testing and the ability to display PSCC or PFC calculations alongside loop resistance for easier measurements. Also includes the Zmax value function
  • RCD - compatible with 10, 300, 300 and 500mA RCDs, as well as type A, AC, S and programmable RCDs. Can perform 1/2, I, I and 5 I tests plus includes automatic RCD tests, ramp tests, 0 and 180° phase angle and touch voltage display from 0 to 230V
  • Voltage Measurements - measure AC/DC voltage from 10V to 600V with true RMS accuracy on AC

Keeping You Safe When Testing

Accidents happen, so the Megger 1711 is made tough and the to the highest standards of safety. As an entry-level tool, having protection in place means the MFT1711 is ideal for new electrical installers who are still training or newly qualified, ensuring that you don't accidentally connect things up wrong or cause potential danger to yourself or others.

The MFT1711's safety features include:

  • Test Lock Out - the MFT1711 will block the test from going ahead if there's live voltage on a circuit when you're trying to measure insulation resistance
  • Safe Contact Detection - audible and visual warnings let you know when you've done something wrong
  • Automatic Discharge - the 1711 will discharge itself after testing, ensuring your safety at all times
  • Dust and Weatherproof Casing Rated to IP54 - use the MFT1711 confidently in all conditions
  • CAT IV 300V Safety Rating - work on any part of an installation without having to carry out risk assessments about the level of supply transients present
