Important notes :
• The si627 P does not require ground connec-
tion (terminal 1).
• In environments with interference problems it
is recommended to connect the instrument to
ground in terminal 1.
It is also recommended to use shielding cable,
both for the electrode signal (triaxial cable) and
the temperature probe.
The external shield of the triaxial cable and the
probe cable must be connected to terminal 10.
• If the temperature probe has a 2-wire cable in-
stead of a 4-wire, fit
a jumper between ter-
minals 6 and 7 and
another one between
8 and 9, as indicated
in the scheme.
