Operating mode
Description
The user can choose between two different
operating modes:
The meter features a non-volatile memory for
storing the dispensing data, even in the event
of a complete power break for long periods.
The measurement electronics and the LCD
display are fitted in the top part of the meter
which remains isolated from the fluid-bath

measurement chamber and sealed from the
outside by means of a cover.
1. Normal Mode: Mode with display of
Partial and Total dispensed quantities.
2. Flow Rate Mode: Mode with display of
Flow Rate, as well as Partial dispensed
quantity.
The only operations that need to be done for
daily use are partial and/or resettable total
register resetting. The user should use only
the dispensing system of meter. Occasionally
the meter may need to be configured or
calibrated. To do so, please refer to the
relevant chapters.
Below are the two typical normal operation
displays. One display page shows the partial
and reset total registers. The other shows the
partial and general total. Switchover from
resettable total to general total display is
automatic and tied to phases and times that
are in factory set and cannot be changed.
NOTE: 6 digits are available for Totals,
plus two icons x 10 / x100. The
increment sequence is the following:
0.0 -> 99999.9 -> 999999 -> 100000 x
10 -> 999999 x 10 ->100000 x 100 ->
999999 x 100

Operating mode
Daily use
Dispensing in normal mode
Normal mode is the standard dispensing.
While the count is made, the partial and
resettable total are displayed at the same
time (reset total).
A few seconds after dispensing has ended, on
the lower register, the display switches from
resettable total to general total: the word
reset above the word total disappears, and
the reset total is replaced by the general
total.
This situation is called standby and remains
stable until the user operates the meter
again.
Partial reset (normal mode)
The partial register can be reset by pressing
the reset key when the meter is in standby,
meaning when the display screen shows the
word “TOTAL”.
WARNING
should one of the keys be accidentally pressed
durinG dispensinG, this will have no effect
After pressing the reset key, during reset, the
display screen first of all shows all the lit-up
digits and then all the digits that are not lit up.
At the end of the process, a display page is
first of all shown with the reset partial and the
reset total
and, after a few moments, the reset total is
replaced by the non resettable Total.
Resetting the reset total
The reset total resetting operation can only
be performed after resetting the partial
register. The reset total can in fact be reset by
pressing the reset key at length while the
display screen shows reset total as on the
following display page:

Operating mode
Daily use
Schematically, the steps to be taken are:
1. Wait for the display to show normal
standby display page (with total only
displayed)
2. Press the reset key quickly.
3. The meter starts to reset the partial.
4. While the display page showing the reset
total is displayed.
Press the reset key again for at least 1
second.
5. The display screen again shows all the
segments of the display followed by all
the switched-off segments and finally
shows the display page where the reset
Reset Total is shown.
Dispensing with flow rate mode display
It is possible to dispense fluids, displaying at
the same time:
1. The dispensed partial.
2. The Flow Rate in [Partial Unit / minute] as
shown on the following display page:
Procedure for entering this mode:
1. Wait for the Remote Display to go to
Standby, meaning the display screen
shows Total only.
2. Quickly press the CAL key.
3. Start dispensing.
The flow rate is updated every 0.7 seconds.
Consequently, the display could be relatively
unstable at lower flow rates. The higher the
flow rate, the more stable the displayed value.
ATTENTION: The flow rate is measured with
reference to the unit of measurement of the
Partial. For this reason, in case of the unit of
measurement of the Partial and Total being
different, as in the example shown below, it
should be remembered that the indicated flow
rate relates to the unit of measurement of the
partial. In the example shown, the flow rate is
expressed in Qts/min.

Replacement battery
WARNING
meter should be installed in a position
allowinG the batteries to be replaced
without removinG it from the system
Meter features two low-battery alarm levels:
1. When the battery charge falls below the
first level on the LCD, the fixed battery
symbol appears. In this condition, meter
continues to operate correctly, but the
fixed icon warns the user that it is
ADVISABLE to change the batteries.
2. If meter operation continues without
changing the batteries, the second
battery alarm level will be reached which
will prevent operation. In this condition
the battery icon starts to flash and is the
only one to remain visible on the LCD.
The word “Gal” remaining alongside the flow
rate refers to the register of the Totals (Reset or
NON Reset) which are again displayed when
exiting from the flow rate reading mode.
IMPORTANT: Even though in this mode they
are not displayed, both the Reset Total and the
General Total (Total) increase. Their value can
be checked after dispensing has terminated,
returning to “Normal” mode, by quickly
pressing CAL.

Maintenance
Replacement battery
Change the batteries, proceed as follows:
1. Press RESET to update all the totals.
2. Loosen the 4 fixing screws of the lower
cover.
3. Remove the old batteries.
4. Place the new batteries in the same
position as the old ones.
5. Close the cover again, by positioning the
rubber protection as a gasket.
6. Meter will switch on automatically and
normal operation can be resumed.
The meter will display the same Reset Total,
the same Total and the same Partial indicated
before the batteries were changed.
After changing the batteries, the meter does
not need calibrating again.
Display positioning
The square shape of the meter body allows
the card to be rotated in its housing, thus
ensuring great versatility in positioning.
This allows easy display readings in any
position. The card housing is closed by a
plastic cover sealed through a rubber
protection acting as a gasket as well. This can
be easily removed unscrewing the 4 screws
that fix both the cover and the card (1).
ATTENTION
while fixinG the meter card, make sure
the battery contact cable is not placed
above the circular housinG of the bulb.

Calibration
When operating close to extreme use or flow rate conditions (close to minimum or
maximum acceptable values), an on-the-spot calibration may be required to suit the real
conditions in which the meter is required to operate.
Definitions
Calibration factor or “K factor“
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:
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.
Calibration mode
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 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.
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 does not need to be repeated.
Fluid water / urea solution or liquid food products
Temperature 20 °C
Flow rate 10 - 30 ltr/min.

Calibration
Calibration mode
Display of current calibration factor
and restoring factory factor
By pressing the CAL key while the
appliance is in Standby, the display
page appears showing the current
calibration factor used. If no calibration has
ever been performed, or the factory setting
has been restored after previous calibrations,
the following display page will appear:
The word “Fact” abbreviation for “factory”
shows that the factory calibration factor is
being used
If, on the other hand, calibrations have been
made by the user, the display page will
appear showing the currently used calibration
factor ( in our example 0,998) .
The word “user” indicates a calibration factor
set by the user is being used...
The flow chart alongside shows the
switchover logic from one display
page to another. In this condition,
the Reset key permits switching
from User factor to Factory factor.
To confirm the choice of calibration factor,
quickly press CAL while “User” or “Fact” are
displayed.
After the restart cycle, the meter uses the
calibration factor that has just been
confirmed.
ATTENTION
when the factory factor is confirmed, the
old user factor is deleted from the memory
