Telurometer AMRU-200

Telurometer AMRU-200

The only meter on the market that implements all measurement methods:

Technical method of 2, 3 or 4 poles

Drive method (4/10μs, 8/20μs, 10/350μs).

Double-clamp method without the need for auxiliary electrodes.

Soil resistivity.

It allows the following measurements to be made:

  • Grounding resistance using auxiliary electrodes
  • Grounding resistance using auxiliary electrodes and tweezers (for multiple grounding measurements).
  • Grounding resistance using double clamps (for grounding measurements when auxiliary electrodes cannot be used).
  • Soil resistivity (using Wenner's method).
  • Current using clamps (e.g. leakage) as well as elastic clamps (harmful current).
  • Measurement of the continuity of compensating and protective connections (complying with IEC 60364-6-61:2000 pt. 6.12.2) with self-neutralisation function - by means of current 200mA

It allows the following measurements to be made:

  • Measurement of the resistance of the auxiliary electrodes Rs and Rh
  • Measurement of the disturbance voltage.
  • Measurement of the frequency of the disturbing signal.
  • Measurement in presence of disturbance voltages in networks with frequency 16 2/3 Hz, 50Hz, 60 Hz, 400Hz (with auto/manual frequency selection).
  • Selection of the maximum measurement voltage (24V and 50V)
  • Enter the distance between the electrodes for resistivity in meters (m) and feet (ft).
  • Storage for 990 measurements (10 banks of 99 cells).
  • Calibration of the clamps used.
  • Real time clock (RTC).
  • Data transmission to the computer (USB).
  • Accumulator power indicator.

It allows the following measurements to be made:

  • Earth resistance by means of auxiliary electrodes
  • Grounding resistance using auxiliary electrodes and clamps (for multiple grounding measurements)
  • Earth resistance with the help of double clamps (to measure the earth)
  • when the auxiliary electrodes cannot be used).
  • Soil resistivity (according to Wenner's method)
  • Current using pliers (e.g. leakage current), as well as elastic pliers (harmful current).
  • Measurement of the continuity of the compensation and protection connections (which respect

IEC 60364-6-61:2000 pt. 6.12.2) with self-neutralisation function - by current 200mA.
