The Metrel MI 3125 Combo Lite is the appropriate instrument for the installation safety testing on TT and TN systems. The bright graphic display with backlight ensures that results, indications, measurement parameters and messages are clear, visible and easy to read. The red and green LEDs on either side of the display provide a clear PASS / FAIL evaluation of test results. EurotestCOMBO contains integrated characteristics of fuses and RCDs for the automatic evaluation of the line / loop impedance results. The handling of the instrument is designed to be as simple and clear as possible. Each test has its own individual help screen describing how to connect the instrument into the installation and how to perform a measurement. MI 3125 performs continuity, insulation, RCD, loop, line, voltage, frequency and phase sequence tests required by the EN 61557 standard.
The Metrel MI3125 Eurotest COMBO Lite Multifunctional Installation Tester has an abundance of outstanding features to make your testing quick, accurate and easy.
With help screens for on site referencing you are able to quickly identify the information and assistance you need, meaning you can feel confident that you are following the correct protocol for each type of testing.
The two LED indicators placed on each side of the Metrel MI3125 EurotestCOMBO Lite’s LCD screen provide PASS / FAIL evaluation of test results.
The large LCD screen featured on the Metrel MI3125 EurotestCOMBO Lite is easy to read and features a bright backlight for use in dimly lit conditions.
The automated RCD testing procedure of the Metrel MI3125 EurotestCOMBO Lite Installation Tester significantly reduces the amount of time it takes to complete testing and the Trip Lock function enables you to perform a loop impedance test without tripping the RCD.
The built-in loop impedance tables featured with the EurotestCOMBO allow automatic evaluation of the line / loop impedance compared to the regulations.
The ability to upgrade the firmware on the Metrel MI 3125 EurotestCOMBO Lite Multifunction Tester allows you to keep your instrument up to date with any changes in regulations, making this product an excellent investment.
