Metrel MI3125 Eurotest Lite Combo Multifunction Installation Tester Details

The Metrel MI3125 Eurotest Lite Combo Multifunction Installation Tester can be used to perform a variety of electrical and safety tests on domestic and industrial installations, as well as single, multiphase, TT and TN systems. This instrument includes the tests required by the EN 61557 standard, such as:

  • TRMS voltage
  • TRMS frequency
  • Phase sequence
  • Line impedance
  • Loop impedance
  • Loop impedance with Trip Lock RCD function (does not trip RCDs whilst testing)
  • RCD testing (general and selective, type AC and A) with an automated testing procedure
  • Continuity of PE conductors with a 200mA test current and an automatic polarity change
  • Insulation resistance (measure up to 1000MΩ) with a DC test voltage (50-1000V)

Additionally, the online voltage monitoring feature allows the user to monitor up to three voltages in real-time.

The Metrel MI3125 Eurotest Lite Combo Multifunction Installation Tester includes a dedicated help screen for each test. Each help page details how to perform the specified test and how to connect the multifunction tester. This adds to the Metrel MI3125’s ease-of-use.

Also adding to this instrument’s ease-of-use are the integrated characteristics of fuses and RCDs which facilitate the automatic evaluation of test results. This instrument also includes built-in loop impedance tables allowing it to evaluate, automatically, the results of line and loop impedance tests in comparison to applicable regulations. The Metrel MI3125 Multifunction tester will indicate whether it deems a result to have passed or failed each test via a red (fail) or green (pass) LED light located on both sides of the LCD display.

Further to this, the user is able to view the measurement, measurement parameters and any messages via the large, graphic, easy-to-read display with a backlight.

Finally, this tester has been optimised for longevity and to this end includes a built-in charger and a set of rechargeable NiMH batteries. The Metrel MI3125 Eurotest Lite Combo Multifunction Installation Tester also includes upgradeable technology ensuring that, if any regulations should change, its firmware can be upgraded to accommodate the most recent information.

The Metrel MI3125 Eurotest Lite Combo Multifunction Installation Tester is ideal for performing an eclectic variety of electrical and safety tests on single and multiphase TT and TN systems in accordance with the EN 61557 standard.
