1.2 Features
(1) High performance
Performance of this instrument surpasses the
requirements of the Japanese standard JISC-
1304-1995 and complies with the safety
standard IEC 61010.
(2) Wide measurement range
Measurement scope was extended to 115% of
the earthing resistance measurement range.
This is useful especially in the 10 Ω and
100 Ω measurement modes which are
important for earthing evaluation during
electrical installation work.
(3) Auxiliary earthing resistance check function
Auxiliary earthing resistance can be checked
for each pole, in order to evaluate possible
influences upon the measurement.
(4) Switchable measurement frequency
Measurement frequency can be changed by the
user, to minimize the influence of harmonic
earth voltage and to assure stable
measurement.
(5) Simplified measurement function
Simplified earthing resistance measurement is
possible using the earth of an AC outlet.
