Use the Timetable to program changes in the pump parameters during the
analysis by entering a time in the Time field and appropriate values in the
following fields of the timetable. Changes in flow rate occur linearly from
either time zero or the time of the last defined change; other parameters
change instantaneously at the time defined in the timetable.

Description
Using Automatic is recommended.
The primary channel can be specified as A to D for optimizing highly
specific methods. It is split up to deliver the first and last solvent package
created by the MCGV in order to optimize composition precision. The
primary channel does not change during a gradient, as long as the channel
is used. Using Automatic chooses the channel with the highest percentage
at start conditions before a gradient.
Click the down-arrow and select the mixer to use from the list:
• Use any mixer: The currently installed mixer is used, irrespective of its
type.
• Do not use mixer: The valve is set to bypass the mixer so that it is not in
the flow path.
• <Mixer Name>: Only the specified mixer may be used; it the mixer is
not found, the pump goes into a Not Ready state.
