Resistance impulse meter of type IMR-4

The resistance impulse meter IMR-4 is a portable device to take earth electrode resistance measurements in the vicinity of DC railway traction systems. The railway or tram tracks (being a part of return circuit) are used for the measurement. Any additional probes are not required. The meter can be used for the measurement of small resistance’s including:

  • continuity of return and working conductors of cables with indication of measured resistance,
  • continuity and quality of connections in bonding and earthing systems,
  • resistance of any short-circuit loop
