CALCAL
CAL
By pressing the CAL key while the appli-
ance is in Standby, the display page ap-
pears showing the current calibration fac-
tor used. If no calibration has ever been
performed, or the factory seing has been
restored aer 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 fac-
tor 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 fac-
to r.
To confirm the choice of
calibration factor, quickly
press CAL while “User” or
“Fact” are displayed.
Aer the restart cycle, the
K24 uses the calibration
factor that has just been
confirmed

I.2.2 IN FIELD CALIBRATION
FOREWORD
This procedure calls for the fluid to be dispensed into a graduated
sample container in real operating conditions ( flow rate, viscosity,
etc.) requiring maximum precision.
NOTICE
For correct K24 calibration, it is most important to:
1
When the Factory Factor is confirmed, the old User factor is deleted
from the memory
2
use a precise Sample Container with a capacity of not less than 5
litres, featuring an accurate graduated indicator.
3
ensure calibration dispensing is done at a constant flow rate equiva-
lent to that of normal use, until the container is full;
4
Not reduce the flow rate to reach the graduated area of the con-
tainer during the final dispensing stage (the correct method during
the final stages of sample container filling consists in making short
top-ups at normal operation flow rate);
5
aer dispensing, wait a few minutes to make sure any air bubbles are
eliminated from the sample container; only read the Real value at the
end of this stage, during which the level in the container could drop.
6
Carefully follow the procedure indicated below.

DISPENSING INTO SAMPLE CONTAINER
Without pressing any key, start dispensing into the sample container
Dispensing can be interrupted and started again at will. Continue
dispensing until the level of the fluid in the sample container has
reached the graduated area. There is no need to reach a preset
quantity.
Indicated value Real value
5
RESET
SHORT RESET key keying
The Meter is informed that the calibration dispensing operation is
finished.
Make sure dispensing is correctly finished before performing this
operation. To calibrate the Meter, the value indicated by the partial
totaliser (example 9.800) must be forced to the real value marked
on the graduated sample container. In the boom le part of the
display an arrow appears (upwards and downwards), that shows the
direction (increase or decrease) of the value change displayed when
the following operations 6 or 7 are performed.

Before performing this operation, make sure the INDICATED value is
the same as the REAL value.
Indicated value Real value
The Meter calculates the new USER K FACTOR ; this calculation
could require a few seconds, depending on the correction to be made
ATTENTION: If this operation is performed aer action (5), without
changing the indicated value, the USER K FACTOR would be the
same as the FACTORY K FACTOR, thus it is ignored.
9
NO OPERATION
At the end of the calculation, the new USER K FACTOR is shown
for a few seconds, aer which the restart cycle is repeated to finally
achieve standby condition.
IMPORTANT: From now on, the indicated factor will become the
calibration factor used by the Meter and will continue to remain
such even aer a baery change
10
NO OPERATION
The Meter stores the new work calibration factor and is ready
to begin dispensing, using the USER K FACTOR that has just
been calculated.
.
I.2.3 DIRECT MODIFICATION OF K FACTOR
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 percent-
age. In this case, the percentage correction of the USER K FACTOR must be calcu-
lated 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 cali-
bration 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).

REPLACEMENT
Use only Piusi Baery code *18021
WARNING
To reduce risk of ignition of a flammable or explosive
atmosphere do not use Volt meter or smiliar powered
tools during the live maintenance.
WARNING
The warranty and the safety of the product is insured
only with the use of baery Piusi code *18021 PIUSI
S.p.A. DENIES LIABILITY FOR DAMAGES CAUSED
BY THE USE OF BAT TERIES NOT SUITABLE.
K24 should be installed in a position allowing the bat-
teries to be replaced without removing it from the
system.
BATTERIES Check the baeries and terminals at least every year
to ensure proper operation. It is strongly recommend-
ed that terminals be cleaned annually
K24 features two low-baery alarm levels:
1
When the baery charge falls below the first level on the
LCD, the fixed baery symbol appears. In this condition,
K24 continues to operate correctly, but the fixed icon
warns the user that it is ADVISABLE to change the bat-
teries.
2
If K24 operation continues without changing the baer-
ies, the second baery alarm level will be reached which
will prevent operation. In this condition the baery icon
starts to flash and is the only one to remain visible on the
LCD.
WARNING
During meter removal, liquid may spill. Follow the liq-
uid manifacturer’s safety precautions for clean up of
minor spills.
TO REMOVE
BATTERY
1 Ensure all liquid is drained from the meter. This could
include draining the hose, meter, nozzle or pipe
2
Wear protective clothing as necessary, loosen both ends
of the meter. Use a wrench only on the meter’s flat metal
surfaces
3 If the meter is not immediately installed again, cap
the hose end or pipe to prevent spills
To reduce the risk of ignition of a flammable or explo-
sive atmosphere, baeries must only be changed in a
non-hazardous location
To prevent ignition of flammable or combustibile at-
mospheres, disconnect power before servicing
To change the
baeries, with
reference to
the exploded
diagram posi-
tions, 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 baeries and disconnect the plug
4
Place the new baeries in the same position as the old ones
(sure to put the baery in the correct way)
5 Close the cover again, by positioning the rubber protec-
tion as a gasket
6 K24 will switch on automatically and normal operation can
be resumed
The K24 will display the same Reset Total, the same Total and the same Partial
indicated before the baeries were changed. Aer changing the baeries, the
meter does not need calibrating again.
CLEANING
Only one operation is necessary to clean the k24. Aer
removing k24 from the plant where it was built in, any re-
sidual elements can be removed by washing or mechani-
cally-handling. If this operation does not restore a smooth
rotation of the turbine, it will have to be replaced.
WARNING
Do not discard the old baeries in the environment.
Refer to local disposal regulations.
Do not use compressed air onto the turbine in order to
avoid its damage because of an excessive rotation
TO STORE Follow the liquid manifacturer’s instructions for the
