A-1 Sieve analysis
During most sieving operations, it is necessary to record the initial weight of each sieve before beginning as the
weights of the sieves may change due to particles being retained from the previous operation. In this procedure, the
basic sample is weighed first with it’s container weight tared. This sample weight is entered into the balance
manually and stored during the procedure. Then, each sieve is weighed in sequence and the weights are stored. After
the screening process, each sieve along with its retained sample, is weighed in sequence. The balance stores the
weight values and automatically subtracts the weight of each sieve and displays the retained amount in a table as
percent retension. Up to 80 sieve weights can be stored.
