Installation Manual
To adjust the
G
parameter valua follow the procedure in paragraph
or via the AfiControl interface mentioned in paragraph
“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 reference values with water.

bucket
7.3.2.3
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 performed 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 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).
Preparation of the 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.
