Only values corresponding to complete dosing
strokes (according to the calibration factor) can be
selected.
Example: If the calibration factor is 23.3 (= 0.233 ml/
stroke), the minimum settable value in timer or batch
mode will be 0.233 ml -> the next will be 0.466 ml ->
the next will be 0.699 ml, etc.
These steps will continue up to a value correspond-
ing to 100 dosing strokes. Above this value, the set-
ting range has standard steps as in other operating
modes.
If the calibration factor is changed after setting of
timer or batch mode, the pump will automatically
recalculate a new amount of dosing strokes per
batch and change the display value to the nearest
possible value compared to the first one set.
