6.4.2 Selecting a solution
Menu ▶ Parameters
Solution
Selection of the solution from the solution list. We recommend always
selecting the solution. Solutions are defined under System
▶ Solutions.
For exchange units with integrated data chip, a check is made in the
method run to verify whether the correct solution has been attached. For
exchange units without integrated data chip, only the cylinder volume is
checked. The validity of the titer is checked for the selected solution at the
start of the determination.

volume used. If this value is exceeded, then no precise sample transfer is
possible.

Volume of the air gap between sample and carrier liquid.
The air gap in the pipetting tubing should have a length of at least 5 mm.
It should however also not be too large in size.
Range 0.0100 ... 49.5000 mL
Default value 0.0500 mL
