Parts Counting Operating Modes
Automatic
When set to automatic the balance allows you to create a database of samples and
average piece weights. Each sample can be labeled with a unique name or an alpha
numeric code and stored in the scale’s internal memory along with its average piece
weight. This eliminates the need for establishing a new average piece weight every time
a part is counted.
Manual
When using parts counting in manual, the database feature is disabled and samples size,
as well as, average piece weight is not stored in the scale’s memory. The sample size
must be manually counted and an average piece weight must be established every time
part counting is performed.
