Over/Under Checkweighing

)
This program is used to check whether products are within a specific tolerance
range, to sort and classify items, and to fill and batch products. Symbols are
displayed above the bar graph as visual aids for this type of program: the equal
sign indicates the target weight; the minus sign, the underweight limit; and the
plus sign, the overweight limit.
Within the tolerance range, the response sensitivity of the bar graph is increased.
You can define the tolerance limits between 0.1% and 10% as required.
To find these setting options, see the chart on page 3–53. The factory setting
is for tolerance limits of +/–1.0%.
For checkweighing, you can choose between two programs:
– checking net weights – code 2 2 3
– checking variations in weight – code 2 2 4
To store a weight readout as the target weight, press f identified by “STO.
This value can be a numeric entry or an ideal sample weight actually on the pan.
The target weight is shown in the analog display as a bar graph. The last segment
of this bar graph ends exactly below the equal sign of the checkweighing
indication. If the weight of a product is “acceptable,” the last segment of the bar
graph will be within the tolerance range of the checkweighing indication.
