5.6 SETTING THE COFFEE VOL-
UME PORTIONS (volumetric
portion control)
A ow meter allows the machine to calculate
the precise co󰀨ee volume you would like from
the single or double porta lter. (Generally 25
to 30ML from the single porta lter and 50 to
60 ML from the double porta lter). When you
are sure the grind setting is correct you can
set the ow meter.
It is important to understand that
the volumetric portion control
will di󰀨er between each pressure
prole. The ow meter will count
total water volume irrespective of
the time it may take.
Example; Pump pressure of 9 bar
over 30 seconds will yield a di󰀨erent
total volume than 5 bar over the
same 30 seconds.
