K1 WHY CALIBRATE?
NOTICE
K2 DEFINITIONS
CALIBRATION FAC-
Multiplication factor applied by the system to the electrical pulses received, to
TOR OR
transform these into measured fluid unit .
"K FACTOR"
FACTORY K
Factory-set default factor. It is equal to 1,000. This calibration factor ensures ut-
FACTOR
most precision in the following operating conditions:
Fluid
Temperature:
Flow rate:
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 y calibration.

FOREWORD
Two procedures are available for changing the Calibration Factor:
1
2
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 meter cannot be used for normal dispensing operations.
In "Calibration" mode, the totals are not increased
NOTE
14
When working in extreme operating or flow conditions, (close
to minimum or maximum acceptable range values), it may be
a good idea to calibrate in the field, in the real conditions in
which the meter has to work..

Display the currently used calibration factor:
Return to factory calibration (Factory K Factor) after a previous cali-
bration by the user
Change the calibration factor using one of the two previously indi-
cated procedures
In-Field Calibration, performed by means of a dispensing operation
Direct Calibration, performed by directly changing the calibration factor
The meter 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.
