G DAILY USE
FOREWORD
Theonly operationsthat needto be donefor daily use are partial and/
or resettabletotalregister resetting. The user should useonly thedis-
pensingsystemof k24. Occasionally themetermay needto be con-
gured or calibrated.Todo so, pleasereferto the relevant chapters.
Beloware the twotypicalnormal operation displays. One display pageshows thepar-
tialand resettotal registers. The other shows the partialand general total. Switchover
fromresettable total to general totaldisplayis automatic and tiedto phasesand times
thatare in factory setand cannotbe changed.
NOTA 6 digits areavailable for Totals, plus two icons x 10 /
x100. Theincrement sequenceis the following:
0.0-> 99999.9-> 999999 -> 100000x 10 -> 999999x
10 ->100000x 100 ->999999 x 100
G.1 DISPENSING IN NORMAL MODE
FOREWORD
Normal mode is the standarddispensing.While thecountis made,the
partial and resettable totalare displayed at thesame time (resettotal).
WARNING Shouldone of the keys be accidentally pressed during
dispensing, this willhave no eect.
STAND BY A few seconds after dispensing hasended, onthe lowerregister,the
display switches fromresettable total to general total: theword reset
above the word total disappears, and thereset total is replacedby
the general total.
Thissituation is called standby and remainsstable until theuser
operates the k24again.
G.1.1 PARTIAL RESET (NORMAL MODE)
Thepartial register can bereset by pressing the resetkey when
the meter is in standby, meaning when the displayscreen
shows the word“TOTAL”.
Afterpressing the resetkey, during reset, thedisplayscreen
rstof all showsall the lit-updigits andthen all thedigitsthat
arenot lit up.
At theend of the process, a displaypage is rstof all shown
withthe resetpartial andthe resettotal
and,after a fewmoments, the reset total is replaced bythe
non resettableTotal.
G.1.2 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 stepsto be takenare:
1 Waitfor the display to shownormal standbydisplaypage
(withtotal only displayed)
2 Pressthe resetkey quickly
3 Themeter startsto resetthe partial
4 Whilethe display pageshowingthe resettotal is displayed
Press the resetkey again for at least 1 second
5 The display screenagain shows allthe segments of the
display followed byall the switched-o segmentsand
nally shows thedisplaypage wherethe resetReset
Totalis shown.
C.2 DISPENSING WITH FLOW RATE MODE DISPLAY
It is possibleto dispense uids, displaying at the same
time::
1 the dispensed partial
2 the Flow Ratein [Partial Unit/ minute]as shown onthe
following display page:
Procedure forenteringthis mode:
1 wait for the Remote Display to go toStandby, meaning
the display screen shows Total only
2 quicklypress theCAL key.
3 Start dispensing
Theow rate isupdatedevery 0.7 seconds. Consequently, the display could be relatively
unstable at lowerow rates. The higher theow rate,the morestable thedisplayed
value.
IMPORTANT Theow rateis measured withreferenceto the unitof
measurement of the Partial. Forthis reason, incase of
theunit of measurementof the Partial andTotal being
dierent, as inthe example shown below, it should be
remembered thatthe indicated owrate relatesto
theunit of measurementof the partial.In the example
shown, theow rateis expressedin Qts/min.
Theword “Gal” remaining alongsidethe owrate
refers tothe register of the Totals (Reset orNON Reset)
which areagain displayed whenexitingfromthe ow
ratereading mode.
Toreturnto “Normal”mode, pressthe CAL keyagain. Ifone of the twokeys RESETor
CAL isaccidentallypressedduring thecount,this will have noeect.
IMPORTANT
Even though in thismodethey arenot displayed,boththe
ResetTotalandthe General Total(Total) increase. Their
valuecan be checked afterdispensing hasterminated,
returningto “Normal” mode,by quickly pressingCAL.
G.2.1 PARTIAL RESET (FLOW RATE MODE)
Toreset thePartialRegister, nishdispensing andwait for
the RemoteDisplayto show a Flow Rateof 0.0 as indicated
in theillustration
thenquickly press RESET
H CALIBRATION
Whenoperating close to extremeuse or ow rate conditions (closeto minimum or
maximum acceptablevalues),an on-the-spotcalibration may be required to suit
the real conditions inwhich theK24 is required to operate.
H1 DEFINITIONS
CALIBRATION
FACTOR OR
“K FACTOR”
Multiplicationfactor applied by thesystem tothe electrical pulses
received, to transform these intomeasured uid units.
FACTORYK
FACTOR
Factory-set defaultfactor. It is equal to 1,000. Thiscalibration factor
ensures utmostprecisionin the following operating conditions:
Fluid water/ureasolutionor liquidfood products
Temperature: 20°C
Flowrate: 10- 30 ltr/min
Evenafter anychangeshave beenmade by theuser,the factoryk
factor canbe restored by means of a simple procedure.
USERK FACTOR: Customized calibrationfactor,meaningmodiedby calibration.
H2 CALIBRATION MODE
Whycalibrate? 1 Display the currently used calibration factor:
2Return to factory calibration(FactoryK Factor) after a pre-
viouscalibration by the user
3Change the calibration factorusing oneof the two previ-
ouslyindicated procedures
FOREWORD
Two procedures are available for changing the Calibration Factor:
1 In-Field Calibration,performedby meansof a dispensing
operation
2 DirectCalibration, performed by directly changingthe
calibration factor
In calibration mode, the partial and total dispensed quantities indicated on thedisplay
screen takeon dierent meanings according to thecalibration procedurephase.
In calibration mode, the K24 cannot beused for normal dispensingoperations.
In“Calibration”mode, the totalsare not increased
ATTENTION TheK24 features a non-volatile memory thatkeeps
thedata concerning calibrationand total dispensed
quantitystoredfor an indenite time,evenin the
caseof a longpower break;after changing the bat-
teries,calibration neednot be repeated.
H.2.1 DISPLAY OF CURRENT CALIBRATION FACTOR

H.2.2 IN FIELD CALIBRATION
FOREWORD This procedure calls for the uid to be dispensed into a gradu-
ated sample container in real operating conditions ( ow rate,
viscosity, etc.) requiring maximum precision.
ATTENTION For correct K24 calibration,it is mostimportantto:
1Whenthe Factory Factoris conrmed, theold User factoris deleted
fromthe memory
2use a preciseSampleContainer witha capacityof not lessthan 5
litres,featuring an accurate graduated indicator.
3ensure calibration dispensing isdone at a constant ow rate equiva-
lentto that of normal use, until thecontainer is full;
4Not reducethe ow rate to reach thegraduated area of thecon-
tainer during thenal dispensingstage (the correct method during
the nal stages of sample container lling consists in making short
top-ups atnormal operation owrate) ;
5afterdispensing,wait a fewminutesto make sureany air bubbles
areeliminated from the samplecontainer; onlyread theReal value

L MAINTENANCE
BATTERY
REPLACEMENT
Use 2x1.5V alkalinebatteries sizeAAA
WARNING K24shouldbe installed in a position allowingthe
batteriesto be replaced without removing it from
thesystem.
K24 features two low-battery alarm levels:
1When the battery charge falls below the rst level on the LCD,
the xed battery symbol appears. In this condition, K24 con-
tinues to operate correctly, but the xed icon warns the user
that it is ADVISABLE to change the batteries.
2If K24 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
ash and is the only one to remain visible on the LCD.
o change the
batteries, with
reference to the
exploded diagram
positions, proceed
as follows
1 Press RESET to update all the totals
2 Loosen the 4 xing 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 pro-
tection as a gasket
6 K24 will switch on automatically and normal opera-
tion can be resumed
The K24 will display the same Reset Total, the same Total and the same Partial indi-
