4.1 General instructions
In general, OPTISWITCH 4000 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 marking (notches), marking the
switching point with vertical mounting. The switching point
refers to water (1 g/cm³ or 0.036 lbs/in³). When mounting
OPTISWITCH 4000 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.
