Metrel MI 3122 SMARTEC Z Line Loop RCD

The MI 3122 SMARTEC Z Line-Loop / RCD is designed specifically for live circuit testing. The instrument contains integrated characteristics of fuses and RCDs for the evaluation of test results. The online voltage monitoring system allows the operator to control what is happening on three simultaneous voltages in real-time. The bright red and green PASS / FAIL lights and help screens for each measurement make the handling of the instrument easy and clear. All the results can be quickly saved on the instrument and then downloaded via the optional A 1291 EuroLink PRO or A 1290 EuroLink PRO Plus software for evaluation and professional report generation after testing. The MI 3122 SMARTEC Z Line-Loop / RCD performs RCD, loop, line, AC voltage, frequency and phase sequence tests required by the EN 61557 standard. FEATURES Supports all live tests on LV-electrical circuits: - Loop impedance / prospective fault current - Line impedance / prospective short-circuit current Built- in fuse characteristics for quick evaluation of measuring results. RCD tests (trip out time, contact voltage, ramp test, Autotest). Testing on 1- and 3-phase systems. Phase sequence test. Metal test button for touch voltage detection. High accuracy non tripping loop test for RCD protected circuits. Pre-programmed limits. PASS/FAIL evaluation of measurement result. Bright GREEN/RED indicators provides visual evaluation of results. Suited for testing on CAT IV installations. Magnetic holder allowes hands-free operation. Built-in battery charger. Two level memory structure for saving of test results and parameters. Basic downloading with EuroLink PRO PC SW package. Compatible with EuroLink PRO Plus PC SW package. USB and RS232 ports.
