Replacing the dosing unit
5.2.1
As a rule, the need for replacing the dosing unit occurs only rarely. The dosing unit has to be replaced, if such a
replacement becomes necessary as a result of a defect, or of an inspection of the titration unit.
The dosing unit is equipped with lateral ribs around its circumference, with one of these ribs being in double
design. This double rib serves as a mark for the correct placement of the dosing unit (Fig. 81).
With <ENTER>/<OK> confirm the «Unit size» and select «Dosing unit exchange» (Fig. 74).
The exchange procedure starts directly with any additional warning!
Please take care that the titration tip is placed in a beaker or in the reagent bottle.
