Scrolling using but
ton, displays 4.2 digits, allows you to see last 5
transactions. Each time button is pressed,
display shows the transaction number and the
amount transferred. It is possible to sum the last
transactions by pressing button. Total is
made depending off in which screens we currently
are, example if we are currently displaying the four-
th transaction, pressing button will
T-04
and the sum of the 4 preceding transactions. It is
possible to do this in any position of the tran-
sactions history.
3.5 SECONDARY FUNCTIONS
The device has some secondary function, neces-
sary to the good operation of the meter which are:
calibration, unit selection and instantaneous flow
rate.
3.5.1 CALIBRATION
The meter is supplied with a pre-calibration car-
ried out for liquid diesel at 20 °C. Calibration is
required when metering a different fluid, after dis-
assembly, at different temperature or after signif-
icant wear. A proving container or a container of
KNOWN volume will be needed for the calibration
procedure. It is recommended that the container
volume be at least 19 liters (5 gallons).

ATTENTON:
the system does not allow a cali-
bration if quantity transferred is under 5 litres.
Calibration procedure
1. Starting from “Partial” screen, fill up the calibra-
tion jug to a known volume; it is important to do
this at a flow rate of minimum 10 litres a minute
without topping up else calibration could be inac-
curate. Use the nozzle fully open.
2. if the displayed quantity is not matching the me-
asured quantity the meter must be calibrated.
3. to enter in calibration mode, display will
show “CAL” blinking
4. to confirm, will display last quantity
transferred blinking in current unit
of measure
5. Increase or decrease that quantity using
or
buttons until correct quantity i displayed.
6. Wait 10 seconds to confirm and save automati-
cally this new calibration.
