The calibration data acquired for the previous solvent reservoir will also
be used for the following solvent reservoir. Depending on the next
solvent and solvent reservoir size, the accuracy will be as follows:

reservoir change, and subsequent power up.
If you fill the solvent reservoir up to the bottleneck (conical and narrow
part of a solvent reservoir), accurate volume estimation will take longer
because the solvent monitor needs at least some measurements with
the solvent level below the bottleneck.
Waste containers only: Depending on the flow rate, calibrating the
waste channel takes typically 5 hours and the waste container volume is
only shown after the calibration has finished.
During the first measurement after the first power up or solvent
reservoir change, a few air bubbles emerge from the end cap. During
normal operation, the following behavior can be observed:
• The solvent monitor lines are filled with air.
• No air bubbles will emerge.
• No solvent will enter the solvent monitor lines.

Remarks
During Ready Check, Chromeleon
issues the following warning: "It is
unknown whether the solvent error
limit for channel x ... has been
reached." That means that the
volume estimations may be
inaccurate even if the next solvent
reservoir is identical to the previous
one.
