WEIGHT CALIBRATION
The calibration function was introduced to have
a univocal correspondence with a possible exter-
nal reference scale.
Select the group to be calibrated.
Press the rotary switch to select the group to be
calibrated.
1 Turn the rotary switch to increase/decrease
the weight value.
2 Select a supply of 100 g of coffee.
In the first case it is sufficient to turn the rotary
switch to the desired value.
NOTE
EXAMPLE: The external scale always reads two
grams more than that displayed: the calibration
value must be set on 98 gr.
In the second case the dispensing must be spe-
cific, as follows:
1 Evaluate the tare weight of a large container
at least 120 g with the external scale.
2 Place the coffee in the filter holder and place
the container on the grid.
3 Confirm calibration.
