Dynamic compensation of checkweigher in packing department

What is the dynamic compensation of Auto checkweigher?
How it is performed?
It is necessary?

So far i know, Dynamic compensation of Auto checkweigher is done in order to establish the limit for upper and lower limit for chechweigher, here 10 consecutive samples are taken to establish the final limit.


Thanks sir
But after we get upper and lower limit then we do dynamic compensation.
Please tell me when we done dynamic compensation can i used one object of which is taken earlier for static weight or we can used 20 consecutive objects .
