Description

It is used for sizing and projecting grounding grids.

• Applications

  • MRU-120 meter was created for the most difficult working conditions.
  • It generates a measuring current exceeding 200 mA, which provides effective measurements of grounding of energy objects such as transformer stations and power stations.

• Specifications

  • Interference voltage: Measurement range(0 V…100 V),Display range(0 V…100 V),Resolution(1V),Accuracy(±(2% m.v. + 3 digits))

• Capabilities

  • The four-lead method provides very accurate measurement of the expected small values of resistance – eliminates the resistance of the test leads connecting the meter to grounding.
  • Measurement of the continuity of protective connections and equipotential bondings with a current exceeding 200 mA meets the requirements of EN 61557-4 standard.
  • Before performing the measurement, the meter checks whether the tested object is a subject to excessive interference voltage, which may indicate additional problems.
