MRU-200-GPS 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, two kinds of measuring impulse 4/10?s, 10/350?s,
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.
built in GPS,
GPS coordinates of the measurement are stored in meter memory.
