K4.1 DISPLAY OF CURRENT CALIBRATION
FACTOR AND RESTORING FACTORY FACTOR.
By pressing the CAL key while the meter 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 fl w chart alongside shows
the switchover logic from one
display page to another
In this condition, the Reset key
permits switching from User fac-
tor to Factory factor.
To confi m the choice of cali-
bration factor, quickly press
CAL while "User" or "Fact" are
displayed.
After the restart cycle, the K24
uses the calibration factor that
has just been confi med

IN FIELD CALIBRATION

FOREWORD This procedure calls for the fluid to be dispensed into a graduated sample con-
tainer in real operating conditions ( fl w rate, viscosity, etc.) requiring maximum
precision.
NOTE For correct meter calibration, it is most important to:
1 When the Factory Factor is confi med, 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 fl w rate equivalent to that of
normal use, until the container is full;
4 Not reduce the fl w rate to reach the graduated area of the container during
the final dispensing stage (the correct method during the final stages of sample
container filling onsists in making short top-ups at normal operation fl w rate) ;
5
after 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, dur-
ing which the level in the container could drop.
6 Carefully follow the procedure indicated below.
