Key Features:
The MI 3125 EurotestCOMBO 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 EurotestCOMBO performs continuity, insulation, RCD, loop, line, voltage, frequency and phase sequence tests required by the EN 61557 standard.
