133 DAILYUSE
FOREWORD The only operations that need to be done for daily use are partial and/or reset-
table total register resetting. The user should use only the dispensing system
of measurement device. 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 incre-
ment sequence is the following:
0.0 -> 99999.9 -> 999999 -> 100000 x 10 -> 999999 x 10 ->100000 x
100 -> 999999 x 100
134 DISPENSINGINNORMALMODE
FOREWORD Normal mode is the standard dispensing. While the count is made, the partial
and resettable total are displayed at the same time (reset total).
WARNING Should one of the keys be accidentally pressed during dispensing, this
will have no effect.
STAND BY 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
measurement device again.

135 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”.
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 reset-
tableTotal.
136 RESETTINGTHERESETTOTAL
The reset total resetting operation can only be performed after reset-
ting 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:
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.

137 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 MODE 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.
The word “Gal” remaining alongside the flow rate refers to the re-
gister of the Totals (Reset or NON Reset) which are again displayed
when exiting from the flow rate reading mode.
To return to “Normal” mode, press the MODE key again. If one of the two keys RESET or MODE is
accidentally pressed during the count, this will have no effect.
ATTENTION 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 MODE.
1371 PARTIALRESETFLOWRATEMODE
To reset the Partial Register, finish dispensing and wait for the Remote Dis-
play to show a Flow Rate of 0.0 as indicated in the illustration
then quickly press RESET.

“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:
Fluid water/urea solution or liquid food products
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 FACTOR: Customized calibration factor, meaning modified by calibration.

Why calibrate? 1Display the currently used calibration factor:
2Return to factory calibration (Factory K Factor) after a previous cali-
bration by the user
3Change the calibration factor using one of the two previously indicated
procedures
FOREWORD Two procedures are available for changing the Calibration Factor:
1In-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 measure-
ment device cannot be used for normal dispensing operations. In “Calibration” mode, the totals are
not increased
ATTENTION The Measurement device 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.

Standby, the display page appears showing the cur-
rent calibration factor used. If no calibration has
ever been performed, or the factory setting has been
restored after previous calibrations, the following dis-

If, on the other hand, calibrations have been made by
the user, the display page will appear showing the cur-
rently used calibration factor ( in our example 0,998) .
The word “user” indicates a calibration factor set by
the user is being used..
MODE
The flow chart alongside

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 cali-
bration factor, quickly press
MODE while “User” or “Fact”
are displayed.
After the restart cycle, the
Measurement device uses

If normal Meter operation shows a mean percentage error, this can be corrected by applying to the
currently used calibration factor a correction of the same percentage. In this case, the percentage
correction of the USER K FACTOR must be calculated by the operator in the following way
New Cal. Factor = Old Cal. Factor * ( 100 - E% / 100 )
EXAMPLE:
Error percentage found: E% - 0.9 %
CURRENT calibration factor: 1.000
New USER K FACTOR: 1.000 * [(100 – ( - 0.9))/100] = 1.000 * [(100 + 0.9)/100] = 1.009
If the Meter indicates less than the real dispensed value (negative error) the new calibration factor
must be higher than the old one as shown in the example. The opposite applies if the Meter shows
more than the real dispensed value (positive error).
