Description
- Multifunction Earth Test Set
- MRU-200 is the only meter in the market which uses all measurement methods.
Possible measurements:
- Earth resistance measurement with 2-pole, 3-pole,4-pole method,
- Impulse earth impedance measurement, three kinds of measuring impulse 4/10μs, 8/20μs, 10/350μs,
- Earth resistance measurement without disconnecting measured earths (using clamp),
- Two clamps earth resistance measurement without auxiliary test probes,
- Earth resistivity measurement using Wenner method
- Continuity measurement,
- Leakage current measurement.
- It allows to take the measurements of:
- Earth resistance using auxiliary electrodes,
- Earth resistance using auxiliary electrodes and clamp (for measurements of multiple earthing)
- Earth resistance using double clamps (for measurement of earthing when it is impossible to use auxiliary electrodes),
- Impulse earth impedance (without disconnecting measured earthing),
- Current using the clamp (e.g. leakage) and flexible clamp (Rogowsky coil),
- Measurement of continuity of equipotential bondings and protective conductors (meeting the requirements of IEC 60364 – 6 – 61:2000 section 6.12.2) with auto-zero function – with current 200 mA.
Additionally:
- Measurement of resistance of auxiliary electrodes RS and RH,
- Measurement of interference voltage,
- Measurement of interference frequency,
- Measurement in the presence of interference voltage in the power network
with frequency 16 2/3 Hz, 50 Hz, 60 Hz and 400 Hz (with automatic selection of proper frequency of measuring signal or with manual selection), - Selection of maximum measuring voltage (25 V and 50 V)
- Introducing the distance between the electrodes for the resistivity in metres (m) and feet (ft),
- Memory of 990 measurements (10 banks of 99 cells each),
- Calibration of clamp used,
- Real time clock (RTC),
- Data transmission to the computer (USB),
- Indication of battery state.
