If the result is negative (Milk meter reading is lower than the actual weight), the calculated
adjustment value needs to be added to the value of
H
. If the adjustment is positive, the
calculated value needs to be subtracted from the value of
H
.
General adjustment calculation → %Dev X ( – 5) = Adjustment value
Example : if the actual value of H in the milk meter is 37 and the measured deviation -4%
(Milk meters show 4% less than actual weight) , modify the “ H ” parameter value
by:
-4 X (-5) = +20 to 57
To adjust the
G
and
H
parameter valua follow the procedure in paragraph Adjusting G
and/or H parameter value or via the AfiControl interface mentioned in paragraph Adjusting
the G and/or H parameter value via communication .
During initial calibration it is the aim to adjust each meter around 0% deviation, while this is
the base for setting the a reference values with water. If a single meter after both G & H
calibration still is deviating, the meter has to be replaced.
7.3.3.3 Setting the reference value by water test
An initial water test is performed after installation of the milk meters, after calibration of
the system or during installation of the entire system. The results of this water test are
the “ reference values ” for the periodic water tests perform ed for each milk meter
annually or more frequently.
Please note that the initial water test is performed to establish a baseline and the
following water tests at the farm are conducted to validate the stability of the system.
Since the device is calibrated for measuring milk rather than water, the deviations
between water measurements and the scaling of the fluid are the baseline tested, rather
than ultimate accuracy of measurements (as calculated in milk tests).
The preparation like needed equipment and how to perform the water test is described
in paragraph 7.3.1.1 Equipment - and water test preparation and description .
At least two measurements per meter with a mutual difference of max. 0,1 kg are recorded.
The reference value for each meter is the average of these two measurements.
