A static test is performed when cows are not present in the parlour. It involves measuring the vacuum level in various parts of the machine, calculating the vacuum reserve, ensuring adequate vacuum pump function and ensuring adequate pulsation (with a suitably long massage phase to ensure teat health).

====Dynamic Tests====

===Dynamic Tests===

Dynamic tests are performed when cows are being milked. The main aim is to measure vacuum fluctuations at the teat end which may not always be suggested as a problem by the results of the static test. Milk flow can also be measured which may reveal problems with bimodal milk flow, suggestive of problems with udder preparation and/or milk let down. It is during such tests that '''liner slip''' may be noticed.
