Reading resolution
:
0.01 Ω in the resistance measurement.
0.01 Ωm in the resistivity measurement.
0.1 V in the voltage measurement.
Output current
:
The short-circuit current is limited to less than
20.0 mA rms
Max. open circuit voltage
:
50 V
Immunity to spurious voltage
interference
:
During the R measurement, it allows for the
presence of spurious voltage up to 7 V~ , with a
error < 10%.
Earth resistance of auxiliary
rods
:
In the R measurement it allows Raux up to 50 kΩ
with error < 30%
Battery status checking
:
The battery charge status is verified under
normal using conditions.
Advanced Features
:
Automated detection of abnormal conditions that
may cause excessive errors (low battery, too
high noise interference, too high test spikes
resistance)
Soil Resistivity Computing
:
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.
Data Output
:
USB
Built-in printer
:
For a printed register document of measured
values.
Power supply
:
By means of an internal rechargeable battery,
LFP 12 V 3 Ah.
