17 AfiMilk MPC Installation Manual7.3.2 Milk test for calibration and reference values by water testThis test is performed by collecting milk of individual cows into a bucket, measuring it andcomparing the amount with the reading of the milk meter. Then, statistical deviationcalculations are done to indicate the accuracy level of the device.It is very important to carry out a proper scaling procedure to ensure accurate scaling inaccordance with regulations.To carry out the scaling procedure, an electronic weighing scale and a few milk buckets arerequired. This chapter describes the correct procedure of scaling and statistical calculations.If deviations in measurements are found, correct those by adjusting G&H values asdescribed above.Before performing the test the following parlor tests and checks should be carriedout:o Milk meters are cleaned properly. Verify functionality and operation of each unit.o Consumable rubber parts (upper and lower gaskets, diaphragm and valve gaskets)are replaced as recommended, and seem flawless and clean.o Clean air line is drained of water, milk meter solenoid air inlet is properly connectedto the clean air line and to the vacuum supply.o Test the vacuum level and stability. Ensure vacuum level above 30 kPa.7.3.2.1 Collecting the Milk into a Milk BucketPer international regulations the following rules are adopted for scaling:o Multiple attachments measurements are not included in the statistics.o Only milking claw air admission is allowed. Tests may not be valid if liners cracks orpiping holes allow additional air intake by the system. Furthermore, tests whereliner slippage or large udder causing squawks (liner slip) occurs are also rejected.Vacuum level (kPa) Parlor: Harringbone (2x5)- at reference determine 42,0 Date:- this routine testNr.
