Schlumberger Method - AEMC 6470-b User Manual

5. 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
W
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 measure-
ment by a long press of the START/STOP button.

2. Place electrodes S (Y) and ES (Xv) at a distance A apart, then place elec-
trodes H (Z) and E (X) in the same straight line, at a distance d measured from
the midpoint of distance A. Distance d must be between 2 and 30m.
3. Drive the electrodes to a depth p of not more than 1/20 of d.
4. Connect the cables to the electrodes, then to terminals H (Z), S (Y), ES (Xv),
and E (X).
5. Program the distance into the instrument as described in § 5.6.3.
