In addition to the basic MI3125-L model, the BT version will test B type RCDs and carry out an earth resistance test.

Designed to be quick and easy-to-use, the Metrel 3125BT Combo has integrated characteristics of fuses and RCDs enable automatic evaluation of Line / Loop impedance and the large graphical, backlit display ensures the results, indications, measurement parameters and messages are clearly visible to you. A unique feature of this 18th edition tester is the red and green LEDs on either side of the display, giving a clear, visual indication of a pass or fail, compared to the user set or automatic limits.

Help screens are provided with each test, indicating how to connect the tester and perform the measurement. Note, this item is not supplied with the Tip Commander remote test probe.
