E is not decreasing: a strip conductor electrode is
advisable.
As measuring results are often distorted and corrupted, for example, by
underground pieces of metal and underground aquifers, a second
measurement, in which the spike axis is turned by an angle of 90 °, is
always advisable (see graph below).

Measurement of Resistances
Resistance Measurement (R~)
This measuring function determines the ohmic resistance between 0.02
Ω
and 300 k
Ω
.
The measurement is done with ac voltage. For measurements of very low resistances a
compensation of the connecting leads is suggested (see Compensation of Measuring
Lead Resistance).
