0.01 Ω in the resistance measurement.
:
0.01 Ωm in the resistivity measurement.
0.1 V in the voltage measurement.
The short-circuit current is limited to less than
:
20.0 mA rms
:
50 V
During the R measurement, it allows for the
:
presence of spurious voltage up to 7 V~ , with a
error < 10%.
In the R measurement it allows Raux up to 50 kΩ
:
with error < 30%
The battery charge status is verified under
:
normal using conditions.
Automated detection of abnormal conditions that
:
may cause excessive errors (low battery, too
high noise interference, too high test spikes
resistance)
When performing soil resistivity measurements,
:
the operator informs to the EM-4058 the distance
between spikes and the equipment automatically
computes soil resistivity using the Wenner full
equation.
