First, the user may choose his own quality criteria.
These are the acceptable minimum and maximum flow rates for the estimated product.
The user needs to choose the type of display « Quality criteria »:
The display during the extraction becomes:
The cursor
moves (7 positions) depending of the measured flow (ml/s).
There are minimum and maximum values for espresso.
There are minimum and maximum values for coffee.
The cursor shows 7 positions matching to 7 values included between the programmed
mini and max.
For example: programmed value: Min =
0.80 ml/s
/ Max =
1,20 ml/s
Position 1 = flow between 0.80 ml/s and 0.86 ml/s
Position 2 = flow between 0.86 ml/s and 0.91 ml/s
Position 3 = flow between 0.91 ml/s and 0.97 ml/s
Position 4 = flow between 0,97 ml/s and 1,02 ml/s
(median position)
Position 5 = flow between 1,02 ml/s and 1,08 ml/s
Position 6 = flow between 1,08 ml/s and 1,14 ml/s
Position 7 = flow between 1,14 ml/s and 1,20 ml/s
