Empty
The [Empty] function can only be carried out with dosing units. The
Empty function empties the cylinder and all the tubing of the dosing
unit. The parameters defined under System/Titrants for preparing the
dosing unit and the tubing parameters are used for emptying (see
Section 3.8.6).
You can use the empty and prepare functions to change easily the
reagent of a dosing unit without coming into contact with chemicals.
Proceed as follows:
Empty the dosing unit with [Empty].
Carry out the [Prepare] function using a suitable solvent to rinse
the dosing unit.
Empty the dosing unit with [Empty].
Carry out the [Prepare] function using the new reagent.
