Valor 5000 Series
Negative Checkweighing
In "Negative" checkweighing, the part of an item subsequently removed from the pan is checked
against the target limits. This method may be preferred in portioning applications.
• Set both targets as negative values, where the lightest acceptable weight is entered as the Under
target limit and the heaviest acceptable weight is entered as the Over target limit.
• Place a quantity of items on the pan.
• Tare the items.
• Remove a portion of the items from the pan.
• The amount removed will be compared to the targets.
"Zero" Checkweighing
In "Zero" checkweighing, displayed results will show the deviation of the sample's weight from a
reference or ideal weight. This approach may be more preferred for grading or sorting applications.
• Set the targets using a negative value (negative tolerance) for the Under limit and a positive value
(positive tolerance) for the Over limit.
• Place the reference weight on the pan.
• Tare the reference weight and remove it from the pan.
• Place the item on the pan to be checked against the reference weight.
• The display will show a negative, positive or '0" value if the sample is less than, more than or equal
to the reference weight, respectively.
