Connection diagram
The connection diagram depicted in Fig. 3.10
shows the connections for an inductive or
conductive measuring cell (dashed lines).
The connection of the various measuring cells
is shown in more detail in Figs. 3.13 to 3.15.
Note:
The instrument has protection class II
and is generally operated without
protective earth connection.
