calibratioNs
volumEtric couNtEr calibratioN
The calibration of the volumetric counter
(ow meter) enables the operator to obtain
the proper water quantity required by reci-
pes.
The calibration procedure of the volumetric
counter consists in:
1. Dispensing and drawing the pre-set wa-
ter quantity;
2. Measuring the dispensed water quantity
(in cc);
3. Enter the measured value.
griNDiNg calibratioN
Calibration enables the user to regulate the
working speed of the grinder, according to
the grams to be ground.
To calibrate, act as follows:
1. After the calibration procedure has been
started, a coffee dose in beans is ground
and released;
2. Weigh the ground product;
3. Enter the value of the weight you have
measured.
iNgrEDiENt motor calibratioN
The calibration of instant product and pre-
ground coee ingredient motors enables
the user to regulate the working speed of
the ingredient motor to dene the ow rate
in gr/sec.
To calibrate, act as follows:
1. Dispense powder at the minimum speed;
2. Weigh the instant powder you have dis-
pensed;
3. Enter the value of the weight you have
measured;
4. Dispense powder at the maximum
speed;
5. Weigh the instant powder you have dis-
pensed;
6. Enter the value of the weight you have
measured.
calibratioN of pumps / solENoiD valvEs
Calibration enables the user to regulate the
ow rate in cc/sec.
To calibrate, act as follows:
1. dispense water at the minimum flow rate;
2. measure and enter the dispensed water
quantity;
3. dispense water at the maximum flow
rate;
4. measure and enter the dispensed water
quantity.

colD watEr calibratioN
For the models dispensing cold water only.
The cold water calibration enables the op-
erator to obtain the proper water quantity in
recipes.
The calibration procedure:
1. dispense a pre-set water quantity;
2. measure the dispensed water quantity
(in ml);
3. enter the measured value.
automatic rEgulatioN of griNDiNg
wHEEls
For each device for the regulation of grind-
ing wheels (if any), you can:
-Enable / disable the automatic grinding
regulation;
-Set up the brew time, i.e. the time you wish
to dispense the water dose of reference
set up (brew dose);
-Set up the water quantity of reference
(brew dose), on the basis of which to
monitor the brew time;
If you change the brew dose, the brew time
is changed proportionally.
If you change the brew time, the brew dose
is not changed.
