Purpose
With the Counting application, you can
determine the number of parts that each
have approximately equal weight. To
do this, a known number of parts (the
reference sample quantity) is weighed first,
and the individual piece weight (reference
weight) is calculated from this result. Thus
the number of parts subsequently placed
on the balance can be determined from
their weight.
