The Tester includes these measurement functions:
•
Earthing Resistance (R
E
)
The earthing resistance is determined by a 3-pole or
4-pole current and voltage measurement. The
measuring voltage is a square pulse ac voltage with
48 / 20 V and a frequency of 94, 105, 111 or 128 Hz.
The frequency can be selected manually or
automatically (AFC).

Selective Measurement of
Earthing (R

)
Measurement of a single earth electrode in a mesh
operated (parallel) earthing system. The current flowing
through the single earth electrode is measured with an
external current transformer.
