MRU-200 is the only meter in the market which uses all measurement methods.
Possible measurements:
earth resistance measurment 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 probs,
earth resistivity measurement,
continuity measurement,
leakage current measurement.
