3.12 Target Deviation Checkweigh
The target deviation method uses a target value in which the upper and lower tolerances are deviated from
the target. The upper and lower tolerances are fixed values. The accept window is varied by adding the high
tolerance to the target and subtracting the low tolerance from the target. This feature is commonly used in
check-weigh applications. The desired target may be based on gross weight, net weight or quantity (if
counting is enabled). The annunciators will light on the indicator display or physical setpoints can be added.
This feature must be enabled before attempting to use.
