Metrel MI 3122 SMARTEC Z Line-Loop & RCD Tester

An ideal tester for professional electrical installers who perform RCD, loop, line, AC voltage, frequency and phase sequence tests required by the EN 61557 standard.

All the results can be quickly saved on the instrument with bright red and green PASS / FAIL lights and help screens for each measurement making handling of the instrument easy and clear.

These results can then downloaded for evaluation using the optional A 1291 EuroLink PRO or A 1290 EuroLink PRO Plus software designed for professional report building.

Online voltage monitoring system allows the operator to control what is happening on three simultaneous voltages in real-time.


Metrel MI 3122 Key Features:

  • Line impedance
  • Loop impedance
  • Loop impedance with Trip Lock RCD function
  • TRMS voltage and frequency
  • Phase sequence
  • RCD testing (general and selective, type AC and A)
  • Help screens: instrument comes complete with built-in help screens for referencing on site
  • LED Pass/Fail indicators: two LED indicators for PASS / FAIL evaluation of test results are placed on both sides of the LCD
  • Built-in fuse tables: this unique feature allows automatic evaluation of the line / loop impedance compared to the regulations
  • Online voltage monitoring: monitors all 3 voltages in real-time
  • Downloadable: downloads via RS232 or USB cable directly to the PC with the help of the optional software
  • Upgradeable: if changes occur to the regulations upgrades can be made to the firmware to keep the instrument up to date
  • Trip Lock function: Zs (RCD) function performs a loop impedance test without tripping the RCD
  • Built-in charger and rechargeable batteries: instrument has a built-in charging circuit and comes complete with a set of rechargeable NiMH batteries
  • RCD auto: automated RCD testing procedure significantly reduces test time
  • Easy to use: large bright LCD display and large buttons enable easy handling of the instrument (even while wearing gloves)
  • Magnetic holder: magnet for fixing instrument on metal surfaces enables hands-free operation


MI 3122 Perfect For:

  • Verification, maintenance and periodic testing of electrical installations
  • Evaluation of protective measures in LV-installations (fuse size, RCD operation)
  • Troubleshooting on live installations
  • Testing on CAT IV installations (distribution side of installations, LV-substations, industrial plants etc)
