The CheckweigherStatisticType defines the structure of an Object that represents the statistic for a checkweigher. Figure 32 shows the hierarchical structure and details of the composition. It is formally defined in Table 53.
The StatisticType is a container for the different statistic values needed in a checkweigher.

PackagesRejectedBySystem defines an optional placeholder for additional categories in which rejected packages may be counted in. The RejectedStatisticCounterType shall be used, if the rejected packages are added to TotalPackagesRejected. The Object representing the rejected package should be named like TotalPackagesRejectedBy<SYSTEM>. <SYSTEM> can be an additional system or reason why the packages are rejected. Some reasons could be:
- OpenFlap
- AskewPackage
- UpperToleranceLimit1
- UpperToleranceLimit2
- Presorting
- …
PackagesRejectedByMetal defines a statistic counter for items rejected by a metal detection system.
PackagesRejectedByVision defines a statistic counter for items rejected by a machine vision system.
PackagesRejectedByXRay defines a statistic counter for items rejected by a x ray detection system.
PackagesRejectedByDistanceFault defines a statistic counter for items rejected by a distance fault.
PackagesRejectedByLength defines a statistic counter for items that rejected due to the item length.
PackagesRejectedByMeanValueRequirement defines a statistic counter for items that rejected due to the required mean value.
PackagesRejectedByLowerToleranceLimit1 defines a statistic counter for items that are lower than the ToleranceLimit1
PackagesRejectedByLowerToleranceLimit2 defines a statistic counter for items that are lower than the ToleranceLimit2
PackagesAcceptedWithProperty defines an optional placeholder for additional categories in which accepted packages may be counted in. The AcceptedStatisticCounterType shall be used, and the accepted packages are added to TotalPackagesAccepted. The Object representing the accepted package should be named like TotalPackagesAccepted<PROPERTY>. <PROPERTY> can be an additional system or reason why the package is accepted.
PackagesAcceptedWithLowerToleranceLimit1 defines a statistic counter for items that are lower than TU1 and upper TU2 but accepted to the “The 3 Packers Rules” of the Welmec 6.4
TotalPackagesRejected defines the totalized number of packages, which were rejected during verification, controlling or weighing processes, that may be upstream or downstream of the weighing process itself.
TotalPackagesAccepted defines the totalized number of packages, which successfully completed all verification, controlling and weighing processes.
GiveAway defines the totalized value of volume deviation from NominalWeight. The giveaway is an indicator of overproduction and is calculated as follows:
PercentageLowerToleranceLimit1 defines the current percentage of accepted items which are lower TU1 and upper TU2 as defined in the CheckweigherType.
