  • Description

Metrel MI 3122 Z Line-Loop / RCD Tester Details

The Metrel MI3122 Z Line-Loop/RCD Tester is made for verification, periodic testing, and maintenance of electrical installations.  It can also be used for the evaluation of protective measures in LV-installations and for troubleshooting on live installations.  The Metrel MI3122 Z Line-Loop/RCD Tester is also suitable for testing on CAT IV installations.

Combining together built-in fuse characteristics for fast evaluation of all measuring results, RCD tests (including trip time out, contact voltage and ramp test), phase sequence testing and the ability to clearly display whether a device has passed or failed a test, the Metrel MI3122 is a fantastic, high-quality tester that gives you the needed flexibility to provide incredibly accurate testing.

The device is also compatible with Metrel’s EuroLink Pro Plus PC Software package, and thanks to the integrated USB/RS-232 ports on the device you can download your stored test to PC and interact further with the data. Perfect for creating comparison charts and graphs!
