5.8.2.3 Negative Counting
Just as you can count by adding parts to the scale, you can also count by removing parts from the scale. This is
called “negative counting” because a negative weight is displayed while counting. Contrary to what may seem
intuitively logical, you do not use the (-) key to do negative counting. The (-) key is only used to delete an entry
in accumulation mode that you want to erase. This procedure does not affect the inventory quantity for this item
stored in the scale. To reduce inventory, see
Section 5.9.3.
NOTE: To utilize the negative counting feature, SPC 3, Bit 1 - Negative Counting must be set to “0: ALLOW”. (For information
on setting Customer specifications, see
Section 3.1.1.)
There are two ways to do this depending on whether at the end you want to see the total amount remaining in the
container or the total amount removed from the container.
