Patent ID: 7957920

Claim:
An arrangement for testing a milking machine, the arrangement comprising: a number of sensors, each sensor being adapted to register a vacuum pressure at a respective test point in at least one fluid conduit of the milking machine; and an analysis unit adapted to compare the registered vacuum pressures with a set of threshold values, and based there- on determine whether or not the milking machine operates acceptably, wherein the analysis unit is adapted to: determine at least one pressure difference between the vacuum pressures registered in at least two of the test points being positioned on a respective side of at least one component in the milking machine with respect to a fluid flow through the at least one component to establish a vacuum drop over the at least one component, compare the vacuum drop with a threshold value to conclude whether or not a test condition is fulfilled, and if the condition is not fulfilled, generate a notification with respect to the at least one component for which the test condition not is fulfilled, wherein at least one first and at least one second test point of the at least two test points are adapted to be positioned on a fluid flow up-stream side and a fluid flow down-stream side respectively of at least one of: a shut-off valve in a milk conduit connected to a teat cup, a shut-off valve in a milk conduit connected to a milking claw, a milk hose, a teat cup, a milk flow meter, a receiver tank, and a sanitary trap.
