Positive Check Weighing
Positive check weighing is used to determine when the material added to the scale is within
the target range. In this case, the under and over limits must be positive values.
(The OVER limit must be greater than the UNDER limit.)
Add material to the scale until it is within the ACCEPT range.
If the item is lighter than the UNDER limit, the yellow UNDER LED will light.
If the item is within the target weight range, the green ACCEPT LED will light.
If the item is heavier than the OVER limit, the red OVER LED will light.
Negative Check Weighing
Negative check weighing is used to determine when the material removed from the scale is within
the target range. In this case, the UNDER and OVER limits are both negative values.
(The UNDER limit must be greater than the OVER limit.)
Place the item to be weighed on the scale and press TARE.
Remove a portion of the item until it is within the ACCEPT range.
If the item is heavier than the UNDER limit, the yellow UNDER LED will light. If the item is within
the target weight range, the green ACCEPT LED will light. If the item is lighter than the OVER limit,
the red OVER LED will light.
