Metrel MI 3100s EurotestEASI Multifunction Tester

MI 3100 s EurotestEASI is a fast, accurate and easy to use multifunctional measuring instrument which performs a basic set of installation safety tests according to IEC/EN 61557. Besides, the MI 3100 s EurotestEASI enables on-line voltage monitoring, phase sequence testing and earth resistance measurement. EurotestEASI is equipped with integrated characteristics of fuses and RCDs for PASS / FAIL evaluation of test results.

Measuring Functions:

  • Insulation resistance with DC voltage from 50 V to 1000 V
  • Continuity of PE conductors with 200 mA test current with polarity change
  • Continuity of PE conductors with 7 mA test current without RCD tripping
  • Line impedance
  • Loop impedance
  • Loop impedance with Trip Lock RCD function
  • TRMS voltage and frequency
  • Phase sequence
  • RCD testing (general and selective, type AC, A, F)
  • Earth resistance (3-wire method)

Other Features:

  •     Built-in help screens for referencing on site.
  •     Built-in fuse tables for automatic evaluation of the line / loop impedance
  •     Monitoring of all 3 voltages in real-time.
  •     Automatic polarity reversal on continuity test.
  •     Loop impedance test without tripping the RCD.
  •     Built-in charger and rechargeable batteries as standard accessory.
  •     Automated RCD testing procedure.
