Automatic Cluster Removal (ACR) Parameters
The Afi-lite milk meter detects when the milk flow rate from the cow has slowed
enough to stop milking, then it removes the cluster.
ACR Parameters
Four parameters are involved in determining when the cluster is removed
and .
determines the minimum amount of time the cluster is attached. This
parameter is also referred to as the "first delay". The value of
multiplied by 10. The resulting value is the minimum number of seconds the
cluster is attached. If the value is 18, then 180 seconds (three minutes) is the
minimum attachment time. If you want to
reduce the minimum attachment time to two and
a half minutes (150 seconds), change the value to
15.

determines the milk flow rate at which milking
will stop. When the flow rate of milk from the
cow decreases, the milk meter body is emptied at
greater intervals. When the milk meter body is
not emptied within the time specified in
Milk flow rate is calculated as follows:
(Near the end of milking, 200 – 220 grams (0.2 kg = 0.44 lb [6.5 oz.]) of milk are released
each time the milk valve is opened. [The amount is measured.] 210 grams (6.7 oz) is used
in the calculations below.)
