The MRU-105 and MRU-106 (for 60Hz) are portable meters for the
earth resistance and earth resistivity measurement (Wenners method). The
instruments can measure resistance using 2, 3, or 4 poles method.
Measurements can be simplified using current clamps. The very high
immunity for existing interference voltage AC + DC at which measurement
is still performed: 24V (68V-p-p) but also measurement of existing
interference voltage up to 40V is unique functionality of the meters.
Moreover meters measure the resistance of the probes and calculate
automatically the error coming from probe's resistances.
The meters MRU-105 and MRU-106 (for 60Hz) additionaly can be powered
from Ni-MH batteries or standard C size, and the test results can be
stored in the internal memory and transmited to PC via USB - cable.
