To configure WAV, set the WAVERSAVER and Numaverages parameters to
establish the speed and required accuracy for dynamic weighing. Set the variation_thd to
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_thd should be set to 9
(1.5X) and the motion_thd parameter set to 2 (1/3X). Note the weight changes will settle to
a 2 increment level
Weight changes smaller than 1:40,000 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
On the 4050 display:
Step 1. Use the Down arrow to select the Setup Menu.
Press the Right or Left Arrow buttons to select the variation_thd or Motion_thd. Enter the
setting for your instrument, and press Enter to save the selection.
On the Web page: Select the options from the Configuration>Setup menu.
Low Pass Filter Parameter
NOTE Low Pass Filter has been replaced in Firmware Version 1.14.0.0 or greater with
WAV using two new parameters: Variation Threshold and Motion
Threshold. The section below is provided for those users whose instruments are
operating with older firmware.
The Low Pass filter can be toggled on or off. When it is on it provides a more stable weight
reading but at the expense of the reaction time. Some applications require the additional
stability. If reaction time is not critical, leave the Low Pass Filter On, otherwise turn it off.
RANGE: ON/OFF (default ON)
On the Web page , from the Low Pass Filter pull-down list,
select ON to turn the filter on or OFF to turn it off. For most
applications the Low Pass Filter should remain ON.
