Check Weighing is enabled only when the Check Weighing Function is selected. This
feature may be used for check weighing or package weight control in any one of the
available weighing units. When in use, the display will show the relationship between
the load on the pan, and the selected target weight. The bar graph will visibly display
where the weight of the load falls in relationship to the under, acceptable, and over
limits. The balance also displays UNDER, ACCEPT, and OVER messages as
appropriate. The default settings are: Reference = Reference weight, Display =
normal.
Two choices are provided for programming the Reference Weight. One choice is the
use of a mass (package, container, etc,) and the other is a number which can be
entered as a high and low limit.
Three choices are provided for programming the display: normal, none, and sign.
Sample displays are shown on the next page.
