Metrel MI3125 Eurotest Lite Combo Multifunction Installation Tester
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.
The Metrel MI3125 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 MI3125 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. Additionally, the online voltage monitoring feature allows the user to monitor up to three voltages in real-time. 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 multifunction 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.
