FACTORY K
FACTOR
Factory-set default factor. It is equal to 1,000. This calibration factor ensures utmost preci-
sion in the following operating conditions:
Fluid water/urea solution
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 FAC-
TOR:
Customized calibration factor, meaning modified by calibration.
8.2 CALIBRATION MODE
Why calibrate? 1
Display the currently used calibration factor:
2
Return to factory calibration (Factory K Factor) after a previous calibration by
the user
3
Change the calibration factor using one of the two previously indicated proce-
dures
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 differ-
ent meanings according to the calibration procedure phase. In calibration mode, the K24 cannot be used for
normal dispensing operations. In “Calibration” mode, the totals are not increased
ATTENTION
The K24 features a non-volatile memory that keeps the data concerning cali-
bration 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.
