Sequence of DIL

height.

burette tip.
Ready to expel the pipetting and diluting volume:
Hold burette tip for pipetting.
Notes
• If you wish to change V-PIP, it is best to change it during filling in the preparation step,
i.e. when display shows
DIL ↓ prep.
.
• If V-PIP is changed at another time, a new preparation step is carried out, which
changes the volume of the air bubble. The first dilution after such a change could be
erroneous and should be discarded. Another possibility is to expel the air bubble in
mode DOS and to start Mode DIL from the beginning. V-DIL can be changed at any
time without a new preparation step.
2.2.6 Mode CNT D, Content Dispenser
Mode CNT D is used to prepare solutions with a particular content. Doing this, the sub-
stance must not be weighed-out to a particular value in order to obtain the preselected
content but the 765 Dosimat dispenses the amount of solvent calculated correspond-
ingly.
