(1) The suffix Act becomes In (for "Input" in English) when this value is recorded by the instru-
ment and then read, to make a distinction between the current and recorded values. In both
cases, this value on the display is associated with its frequency.
(2) In this case, the resistances of the 4 rods used for measurement are indicated by R

: measuring lead compensation resistance
: S (Y) terminal (reference potential socket for calculating earth
resistance)
: external voltage currently present on the instrument terminals
(1)
: voltage measured between terminals H and E
: voltage generated by the instrument between terminals H and
E (32V or 16V)
: voltage measured between terminals S and E
: voltage measured between terminals S and ES
: frequency chosen by the user
: voltage of terminal S (compared with E) expressed as a
relative value (rEL); value without unit
: ground resistivity measured according to the Schlumberger
method (expressed as Ω.m)
: ground resistivity measured according to the Wenner method
(expressed as Ω.m)
