4.1 General instructions
In general, OPTISWITCH 5100 C, 5150 C can be mounted in
any position. The instrument must be mounted in such a way
that the tuning fork is at the height of the requested switching
point.
The tuning fork has lateral markings (notches), marking the
switching point with vertical mounting. The switching point
refers to water with the basic setting of the sensitivity switch
>=0.7 g/cm³ (>=0.025 lbs/in³). When mounting OPTISWITCH
5100 C, 5150 C, make sure that this marking is at the height of
the requested switching point. Keep in mind that the switching
point of the instrument is shifted if the medium has a density
other than water - water =1 g/cm³ (=0.036 lbs/in³). For
products <0.7 g/cm³ (<0.025 lbs/in³) and >0.5 g/cm³
(>0.018 lbs/in³) the density switch must be set to >=0.5 g/cm³.
