Display symbol:

Purpose
With the Counting program you can
determine the number of parts that each
have approximately equal weight. To do
this, a known number of parts (the refer-
ence 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/scale can be
determined from their weight.
