Measurement Cable Compensation
The resistance of the respectively connected measurement cable
or the country-specific measuring adapter must be compensated
for each earth resistance measurement, i.e. it must be subtracted
from the measurement results as an offset. Proceed as described
in
section 4.5
under „OFFSET RL-PE / RN-PE / RL-N“ on page 12
to this end in order to ascertain offset values RLPE-OFFSET and
RNPE-OFFSET.
