If a different filter selection is used other than the 8 second filter, refer to
Table 5-2 for minimum weight required multiplication factors. Take the
minimum weight required value from the table using the 8 second filter and
multiply it by the factor for the specified filter selection. This will yield the
minimum weight required for the new filter selected.
Note, however, that parts counting based on weight is dependent on a
reasonably consistent part weight. Some plastic parts vary in weight from
piece to piece by 10% or more. Attempting to count these items with a
high degree of accuracy will require a very large hand-counted random
sample of the items during the piece weight calculation process. The
minimum accuracy assurance is intended to guide the operator in
sampling parts with a fairly consistent piece weight.

Several ways to count parts using the 60 Series indicators:
Method 1: Counting a specific number of parts
1. Access the quantity mode.
2. Place the empty container on platform (optional).
