SAFETY INSTRUCTION AND WARNINGS
WhilexingtheK24
card, make sure the bat-
tery contact cable is not
placed above the circular
housing of the bulb.
3.1. DISPLAY POSITIONING
The square shape of the k24 body
allows the card to be rotated in
its housing, thus ensuring great
versatility in positioning.
4. OPERATING MODES
The user can choose between two different operating modes:
l Normal Mode: Mode with display of Partial and Total dispensed quantities.
l Flow Rate Mode: Mode with display of Flow Rate, as well as Partial dispensed quantity.
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 tted in the top part of the K24 which remains
isolated from the uid-bath measurement chamber and sealed from the outside by means of a cover.
6. USER BUTTONS
The k24 features two buttons (reset and cal) which individually perform two main functions and, together, other
secondary functions. The main functions performed are:
lFor the reset key, resetting the partial register and resettable total (reset total)
lFor the cal key, entering instrument calibration mode.
Used together, the two keys permit entering conguration mode, useful for changing the units of measurements and
calibration factor.
7. BATTERY HOUSING
The k24 is powered by two standard type 1.5 V batteries (size AAA). The battery housing, easily accessible, is closed
by a metal cover sealed through a rubber protection acting as a gasket as well. The whole unit can be easily removed
by unscrewing the 4 screwsxingthe cover and the protection to the body.
8. INSTALLATION

9. DAILY USE
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 k24. Occasionally the meter may need to be congured or calibra-
ted. 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. Switcho-
ver from resettable total to general total display is automatic and tied to phases and times that are in factory set and
cannot be changed.
10. CALIBRATION
10.1. DEFINITIONS
Calibration factor or „K factor“. Multiplication factor applied by the system to the electrical pulses received, to trans-
form these into measured uid units.
FACTORY K FACTOR:
Factory-set default factor. It is equal to 1.000. This calibration factor ensures utmost precision in the following opera-
ting conditions:
uidTemperature: Dieselfuel20°C
Flowrate: 10-120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.
10.2. WHY CALIBRATE
When operating close to extreme conditions, such as for instance with uids close to acceptable range extremes (like
diesel fuel at low temperatures) or in extreme ow rate conditions (close to minimum or maximum acceptable values),
an on-site calibration may be required to suit the real conditions in which the k24 is required to operate.
10.3. CALIBRATION PROCEDURE
K24 permits making quick and precise electronic calibration by changing the calibration factor (k factor).
There are 2 different ways of calibration:
l On-site calibration, performed by means of a dispensing operation.
l Direct calibration, performed by directly changing the k factor.
To enter the calibration phases it is necessary to press and hold down the „CAL“ button.
Why enter the calibration phases?
l Display the currently used calibration factor
l Return to factory K factor after a previous calibration with user k factor
l Change the calibration factor using one of the two previously indicated procedures.
In calibration mode, the partial and total dispensed quantities indicated on the display screen take on different
meanings according to the calibration procedure phase. During the calibration, the k24 cannot perform any normal
dispensing operations. In calibration mode, the totals are not increased.
WARNING
The k24 features a non-volatile memory.
It keeps the calibration and dispensing data stored even after replacing new batteries or long peri-
ods of inactivity.
IMPORTANT
Theow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owraterelatestotheunitofmeasurement
ofthepartial.Intheexampleshown,theowrateisexpressedinQts/min.
Theword„GAL“remainingalongsidetheowratereferstotheregisterof
theTotals(ResetorNONReset)whichareagaindisplayedwhenexiting
fromtheowratereadingmode.
To return to „Normal“ mode, press the CAL key again. If one of the two keys RESET or CAL is accidentally pressed
during the count, this will have no effect.
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.
PARTIAL RESET
To reset the Partial Register,nish dispensing and wait for the Remote Display to show a
Flow Rate of 0.0 as indicated in the illustration then quickly press RESET
9.4. DISPENSING WITH FLOW RATE MODE DISPLAY
Itispossibletodispenseuids,displayingatthesametime:
lthe dispensed partial
l the Flow Rate in [Partial Unit / minute] as shown on the following display page:
Procedure for entering this mode:
l wait for the Remote Display to go to Standby, meaning the display screen shows Total only
l quickly press the CAL key.
l Start dispensing
The ow rate is updated every 0.7 seconds. Consequently, the display could be relatively unstable at lower ow rates.
The higher the ow rate, the more stable the displayed value.
9.1. 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).
Should one of the keys be accidentally pressed during dispen-
sing, this will have no effect.
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 k24 again.
9.2. PARTIAL RESET
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 rst
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 rst of all shown
with the reset partial and the reset total and, after a few mo-
ments, the reset total is replaced by the non resettableTotal.
9.3. 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:
Schematically, the steps to be taken are:
l Wait for the display to show normal standby display page (with
total only displayed),
l Press the reset key quickly
lThe meter starts to reset the partial
l While the display page showing the reset total is displayed
Press the reset key again for at least 1 second
l The display screen again shows all the segments of the display
followed by all the switched-off segments and nally shows the
display page where the reset Reset Total is shown.
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

10.4. DISPLAY OF CURRENT „K FACTOR“ AND RESTO-
RING „FACTORY“ K FACTOR
By pressing the cal key while the appliance is in standby, the
display page appears showing the current calibration factor
used.
If you are using k24 with „factory k factor“ the display page
shown in the diagram will be displayed, with the word „FACT“.
If one „user k factor“has been set, the calibration factor set by the user (in our example 0.998) will be displayed. The
word „USER“ indicates a calibration factor set by the user is being used.
The ow 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

K24 is informed that the calibration
procedure is nished. Before doing this,
make sure the DISPLAYED factor is the

K24 calculates the new USER K FACTOR. This calculation could require a few seconds,
depending on the correction to be made. During this operation the arrow disappears but
the CAL indication remains.
If this operation is performed after operation (5), without changing the indicated value,
the USER K FACTOR would be the same as the FACTORY K FACTOR, thus it is
ignored

9NO OPERATION
The K24 stores the new work calibration factor and is ready to begin dispensing, using
the USER K FACTOR that has just been calculated
Indicated value Real value
10.7. DIRECT MODIFICATION OF K FACTOR
This procedure is especially useful to correct a „mean error „obtainable on the basis of several performed dispensing
operations. If normal K24 operation shows a mean percentage error, this can be corrected by applying to the current-
ly used calibration factor a correction of the same percentage. In this case, the percentage correction of the USER K
FACTOR must be calculated by th(e operator)in the following way:
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).
11. METERS CONFIGURATION
Some models of meter feature a menu with which the user can select the main measurement unit, Quarts (Qts), Pints
(Pts), Litres (Lit), Gallons (Gal). The combination of the unit of measurement of the Partial register and that of the
Totals is predened according to the following table:
To choose between the 4 available combinations:
l Wait for K24 to go to Standby,
l Press the CAL and RESET keys together. Keep these pressed until the word „UNIT“ appears on the screen
together with the unit of measurement set at that time (in this example Litres / Litres)
l Press the reset key to select the desired combination of unit of measurement, amongst those shown below.
l Save the new combination by pressing the cal key at length. K24 will pass through the start cycle and will then
be ready to dispense in the set units.
WARNING
The Resettable Total and Total registers will be automatically changed to the new unit of measure-
ment. NO new calibration is required after changing the Unit of Measurement.
