Metrel MI 3125 BT Combo Multifunction Installation Tester

Metrel MI 3125 BT COMBO 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 3125 BT offers the brand new ability to test B-type (DC sensitive) RCDs.

The MI3125 BT COMBO is perfect for: Electrical power systems, industrial systems, building‘s facility management, special installations / locations & general purpose system maintenance.

 

Metrel MI 3125 BT Key Features:

  • Contains integrated characteristics of fuses and RCDs (including EV type) for the evaluation of line/loop impedance results
  • Bright graphic display: the backlight ensures that results, indications, measurement parameters and messages are clear, visible and easy to read
  • Clear PASS/FAIL: 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
    • All the results can be quickly saved and referenced on the instrument and then downloaded via the MESM software.
  • Help screens: instrument comes complete with built-in help screens for referencing on site
  • Earth resistance measurement: instrument performs 3-wire earth resistance testing with two additional rods
  • 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
  • Upgradeable: if changes occur to the regulations, upgrades can be made to the firmware to keep the instrument up to date
  • Polarity swap: automatic polarity reversal on continuity test
  • Insulation range: wide range of insulation test voltages from 50 V to 1000 V, reading up to 1000 MΩ
  • Trip Lock function: Zs (RCD) function performs a loop impedance test without tripping the RCD
  • Multi-system testing: tests on single and multiphase TT and TN systems
  • Built-in charger and rechargeable batteries: unit 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
  • B type RCD testing: is supported
  • BT connectivity: it enables BT communication with Android tablets and smart phones via built-in BT
  • PC SW Eurolink PRO: included in the standard set enables downloading of test results and parameters and creation of test reports

 

Metrel MI 3125 BT Measuring Functions:

  • Insulation resistance with DC voltage
  • Continuity of PE conductors with 200 mA test current with polarity change
  • Continuity of PE conductors with 7 mA test current (continuous measurement) without RCD tripping
  • Line impedance
