With the potentiometer you can adapt the switching point to the
solid. It is already preset and must only be modified in special
cases.
By default, the potentiometer of OPTISWITCH 3100 C is set to
the right stop (>0.02 g/cm³ or >0.0008 lbs/in³). In case of very
light-weight solids, turn the potentiometer to the left stop
(>0.008 g/cm³ or >0.0003 lbs/in³). OPTISWITCH 3100 C will
thus be more sensitive and can detect light-weight solids more
reliably.
For instruments detecting solids in water, these values are not
applicable. The potentiometer is preset and must not be
changed.
With the mode adjustment (min./max.) you can determine the
output current.
When using a signal conditioning instrument, always set the
mode switch to max. mode.
In this case, you select the requested mode acc. to the
"Function chart" (max. - max. detection or overfill protection,
