WAV Options: Variation Threshold and Motion Threshold

(HI 6500-XP and HI 6510-XP only)
WAV is a superset of WAVERSAVER that uses two entirely new parameters,
Variation Threshold and Motion Threshold. These two parameters add a patent-pending
adaptive filtering algorithm to the WAVERSAVER output that provides stability to weight
readings of up to 1:30,000.
On the
web page:
configure WAV by first setting the WAVERSAVER and
Numaverages parameters to establish the speed and required accuracy for dynamic
weighing. Set the Variation Threshold 0.0 and observe the peak to peak variation of the
weight value. Then set the variation threshold parameter to be 1.5 times larger than the
observed weight variation. Set the Motion Threshold to 1/3 of the observed peak to peak
weight variation.
For example, if the observed weight change is 6, set the Variation Threshold should be set
to 9 (1.5X) and the Motion Threshold parameter set to 2 (1/3X). Note that he weight
changes will settle to a 2 increment level.
Weight changes smaller than 1:30,000 will need considerations for environmental
protections from air movement forces and additional WAVERSAVER and NumAverages
settings.
The default factory setting is 0.0; which turns WAV OFF
