7.5 Adjusting the set pointers

The adjustment of the set points is
achieved using the adjustment lock
in the window with the aid of the
adjustment key (included in delivery).
The set pointers for the limit switches are freely adjustable over the full scale range. For
reasons of switching accuracy and service life of the mechanical measuring systems, the
switch points should be between 10 % and 90 % of the measuring range.
