STANDARD DOSES
With this function you can recall the values of
"standard doses" for the groups. The display
shows:
Select the coffee group to which the programmed
"standard doses" apply and confirm by pressing
the rotary switch.
WEIGHT COMPENSATION
(only Gravimetric version):
Using this function, it is possible to introduce a
weight compensation value.
This parameter allows you, at the end of dispens-
ing, to obtain the actual value set in program-
ming: Since when the solenoid closes the coffee
group continues to drop, the quantity measured
in the cup is slightly more than that set by pro-
gramming.
Every coffee has its specific compensation,
linked to the characteristics that distinguish it.
These quantities to be compensated depend
on the dispensing: the value will differ between
a single coffee dispensed and a double coffee
dispensed.
By setting this parameter the machine will stop
dispensing sooner based on the compensation
value established.
The compensation value can vary from a mini-
mum of 0.0 g to a maximum of 5.0 g with varia-
tions of 0.5 g.
