10 AfiMilk MPC Installation Manual7.3 Accuracy AdjustmentAfiMilk MPC milk meters are supplied with default adjustment calibration values. After theinitial setup (see adjustment per air intake explained above) inaccuracies of milkmeasurements vs. bulk tank OR in specific milk meters can be found; therefore G and Hparameters values may need further adjustment. Initial calibration (after installation) isperformed by adjusting the G parameter value. If additional – fine tune calibration – isrequired for individual milk meters, update the H parameter value according to theprocedure explained here.Local authorities may require an initial calibration and periodic accuracy checks (usuallyyearly) of the milk meters, mainly for herd book approval. This can be done by threedifferent methods. These methods will be described here. The periodic accuracy check orperiodic routine test is usually done as a water test which will be compared to water testreference values set during or after the initial calibration (see document Afimilk MPCPeriodic routine test).o Compaire between bulk tank vs. milk measurements with fine adjustment with awater test (minimal required for official recording).Based on the comparison, the G parameter is set equal for all meters. A water test isfulfilled to check differences (i.e. faulty meters) and set a farm avarage as thereference value. Based on the individual meter results (minimum of twomeasurements) a G parameter adjustment for each meter is done. If adjustment isneeded for more then 5 points (2%), a minimum two new water tests are requiredand are then used as the reference value for this meter.o Milk test for calibration and meter adjustment followed by a water test for futurereference values (recommanded by Afimilk).Based on a milk test of at least three valid readings the G parameter will be adjusted.After all milk meters are calibrated, a water test is performed for each meter. This willbe used as reference value.o Milk test for calibration and meter adjustment (advanced calibration with H-parameter).Based on a first milk test of at least three valid readings the G parameter will beadjusted. A second milk test, which might include milk speed data, is used to adjustthe H parameter. After all milk meters are calibrated, a water test is performed foreach meter. This will be used as the reference value. |
