: How does it function:
During an extraction the group display shows:
The cursor
moves on 7 positions on the display:
o
Between the minimum and maximum values of the Espresso or Coffee
o
Depending of the measured flow rate of the coffee (ml/s).
The 7 positions corresponds to 7 range of coffee flowrate values between the mini and max.
For example: programmed value: Min = 0.80 ml/s / Max = 1,20 ml/s
o
Position 1 = flow between 0.80 ml/s and 0.86 ml/s
o
Position 2 = flow between 0.86 ml/s and 0.91 ml/s
o
Position 3 = flow between 0.91 ml/s and 0.97 ml/s
o
Position 4 = flow between 0,97 ml/s and 1,02 ml/s (median position)
o
Position 5 = flow between 1,02 ml/s and 1,08 ml/s
o
Position 6 = flow between 1,08 ml/s and 1,14 ml/s
o
Position 7 = flow between 1,14 ml/s and 1,20 ml/s
