13.8 CALIBRATION
When operating close to extreme use or flow rate conditions (close to minimum or maximum accept-
able values), an on-the-spot calibration may be required to suit the real conditions in which the mea-
surement device is required to operate.
13.8.1 DEFINITIONS
CALIBRATION
FACTOR OR
“K FACTOR”
Multiplication factor applied by the system to the electrical pulses received, to
transform these into measured fluid units.
FACTORY K
FACTOR
Factory-set default factor. It is equal to 1,000. This calibration factor ensures
utmost precision in the following operating conditions:
Fluid
water/urea solution or liquid food products
Temperature: 20°C
Flow rate:
10 - 30 ltr/min
Even after any changes have been made by the user, the factory k factor can
be restored by means of a simple procedure.
USER K FACTOR:
Customized calibration factor, meaning modified by calibration.
13.8.2 CALIBRATION MODE
Why calibrate?
1
Display the currently used calibration factor:
2
Return to factory calibration (Factory K Factor) after a previous cali-
bration by the user
3
Change the calibration factor using one of the two previously indicated
procedures
FOREWORD
Two procedures are available for changing the Calibration Factor:
1
In-Field Calibration, performed by means of a dispensing operation
2
Direct Calibration, performed by directly changing the calibration factor
In calibration mode, the partial and total dispensed quantities indicated on the display screen take on
different meanings according to the calibration procedure phase. In calibration mode, the measure-
ment device cannot be used for normal dispensing operations. In “Calibration” mode, the totals are
not increased
ATTENTION
The Measurement device features a non-volatile memory that keeps the
data concerning calibration and total dispensed quantity stored for an
indefinite time, even in the case of a long power break; after changing
the batteries, calibration need not be repeated.
13.8.3 DISPLAY AND RESTORING K-FACTOR

MODE
MODE
By pressing the MODE key while the appliance is in
Standby, the display page appears showing the cur-
rent calibration factor used. If no calibration has
ever been performed, or the factory setting has been
restored after previous calibrations, the following dis-
play page will appear:
The word “Fact” abbreviation for “factory” shows that
the factory calibration factor is being used
