Note
Multiple rod electrodes which are connected
to several signal conditioning instruments or
a multiple channel instrument, require an
earth rod to avoid influencing among the
signal conditioning instruments.
Conductive measuring system
Connect several VEGATOR 256 C absolutely
identical, i.e. the first supply line to all
terminals no. 7 and the second supply line to
all terminals no. 8. An interchanging of no. 7
and no. 8 or the connection of different
phases is not permitted.
