I CALIBRATION
FOREWORD
K900 is supplied with a factory calibration that ensures precise measuring in
most operating conditions. Nevertheless, when operating close to extreme
conditions, such as for instance:
*
with fluids close to acceptable range extremes (such as low-viscosity anti-
freeze)
*
in extreme flow rate conditions (close to minimum or maximum acceptable
values)
I1 DEFINITIONS
Calibration factor
or “K Factor”
this is the 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
DIESEL (EN590)
Temperature: 20°C
Flow rate:
50-255 litres/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.
I2
CALIBRATION PROCEDURE
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
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 differ-
ent 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
ATTENTION
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.
