5. Program the distance into the instrument as described in § 5.6.3.
In order to avoid electromagnetic interference, it is best to unwind the full length of
each cable from the reel, to keep the cables as far apart as possible on the ground,
taking care not to form loops, and to avoid placing the cables near or parallel to
metallic conductors (cables, rails, fences, etc.).
6. Start the measurement by pressing the START/STOP button.
To display the measurement parameters, press DISPLAY several times.
The device displays the following parameters:
ρ , R , d, U
S S-ES
To measure the resistances of the auxiliary electrodes H (Z), S (Y), ES (Xv),
and E (X), or if the resistance of the electrodes is too high (see § 10.1), start the
measurement by a long press of the START/STOP button.
