Installaltion, use and maintenance
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
shows the switchover logic
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
the calibration factor that
has just been confirmed

13.8.4 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 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).
