EARTH RESISTANCE TESTER MRU-20

Possible measurements:

  • earth resistance measurment with 3-pole method,
  • measurement of continuity of equipotential bondings and protective conductors with auto-zero function - with current 200 mA,
  • resistance measurement using 2-pole method.

Additionally:

  • AUTO-OFF function after 5 minutes,
  • indication of battery state.

It allows to take:

  • earth resistance measurement using auxiliary probes with 3-pole method,
  • resistance measurement using 2-pole method,
  • measurement of continuity of equipotential bondings and protective conductors (meeting the requirements of IEC 61557 - 4) with auto-zero function – with current 200 mA.

Additionally:

  • AUTO-OFF function after 5 minutes,
  • indication of battery state.

Measurement of earthing resistance 
measurement range to IEC61557 - 5:

  • 0,50 Ω...1,99 kΩ Un=50 V;
  • 0,68 Ω...1,99 kΩ dla Un=25 V
