With the potentiometer you can adapt the switching point to the

solid. It is already factory-preset and must be adjusted only in

special cases.

By default, the potentiometer of OPTISWITCH 3100 C is set to

mid position (>0.02 g/cm³ or >0.0008 lbs/in³). In case of very

light-weight solids, you have to turn the potentiometer to the

complete left position (>0.008 g/cm³ or >0.0003 lbs/in³).

Hence the OPTISWITCH 3100 C will 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
