The Metrel MI 3125BT is the ideal instrument for engineers who perform high volume testing or work regularly on TT and TN systems. Containing all necessary tests for installation safety testing, MI 3125BT offers the brand new ability to test B-type (DC sensitive) RCDs. COMBO contains integrated characteristics of fuses and RCDs (including EV type) for the evaluation of line/loop impedance results.

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. Each test has its own individual help screen describing how to connect the instrument into the installation and how to perform a measurement.

MEASURING FUNCTIONS
