3.3 Establishing the tubing connections
Depending on the peripheral devices you are using with the measuring
instrument (manual, semiautomated or automated determinations), differ-
ent tubing connections have to be established. All tubing connections that
can be used are described below.
3.3.1 Installing the fourfold micro dosing tip
The fourfold micro dosing tip (6.1824.000) can be used to connect the
894 Professional CVS to dosing devices of the type 800 Dosino and to
dose auxiliary solutions and standard solutions automatically. Information
on the electrical connection of dosing devices can be found in Chapter
3.4.2, page 40.
Installing a fourfold micro dosing tip in the RDE measuring
head
Proceed as follows:
1 Remove the stopper from the screw nipple of the threaded opening
(5-16).
2 Loosen the screw nipple in the threaded opening a little.
This slightly loosens the O-ring located on the bottom of the screw
nipple.
3 Feed the fourfold micro dosing tip through the opening from below
(5-14).
4 Insert the fourfold micro dosing tip into the screw nipple of the
threaded opening (5-16) until it stops.
