Digital Rolling Average Filter Procedure
1. In setup mode, set the rolling filter stage parameters ( DGFLTR1-3 ) to 1.
2. Set DFTHRH to NONE .
3. Return to weigh mode.
4. Remove all weight from scale, then watch the indicator to determine the magnitude of vibration effects on the scale.
5. Record weight below which all but a few readings fall. This value is used to calculate the
DFTHRH parameter in step 8 .
Example – if a heavy-capacity scale (10000 x 5 lb) produces vibration-related readings of up to 50 lb, with occasional
spikes up to 75 lb, record 50 as the threshold weight value.
6. Place the indicator in setup mode and set the filter stage parameters ( DGFLTR1-3 ) to eliminate the vibration effects on
the scale (leave DFTHRH set to NONE ).
7. Find the lowest effect value for the DGFLTR1-3 parameters.
If needed, the digital filter cutout sensitivity ( DFSENS ) and the digital filter cutout threshold ( DFTHRH ) can be used to reset the
digital rolling average filter so the response to a rate change is faster.
8. Calculate the DFTHRH parameter value by converting the weight value recorded in step 5 to display divisions
( Threshold_Weight_Value / Display_Divisions ).
In the example in step 5 , with a threshold value of 50, and a display divisions value of 5, set the DFTHRH parameter to
10 display divisions.
9. Set the DFSENS parameter high enough to ignore transient peaks. Longer transients (typically caused by lower
vibration frequencies) causes more consecutive out-of-band readings; set the DFSENS parameter higher to counter
low frequency transients.
