3.4 Configuration
3.4.1 Depot
General information about Depot
The dialog window DEPOT can be opened via Configuration, Depot... .
The Components (see section 3.4.2) connected to the instrument
need to be defined in the Depot. The numbers correspond to the num-
bers of the Component connections 5 on the instrument.
Window "Depot"
Define and describe each Component connected to the instrument
under the corresponding number. Save the Depot you have drawn up
as a .meco file. The settings in the Depot must always be edited when
alterations are made to the connected Components.
The Methods (see section 3.3) are based on the Depot that was
loaded when they were drawn up. This means that overwriting an exis-
ting Depot influences the Methods that are based on this Depot.
In order for the mixing process to supply the desired result, the Com-
ponents specified in the Depot must correspond to the Compo-
nents physically connected to the instrument. The concentrations/-
amounts defined in the Depot will be used for the volume calculations
in the Method.
