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:

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; aer changing the baeries, calibration

need not be repeated.
