Adaptive Filter Threshold (ADTHRH)
Set the adaptive filtering threshold ( ADTHRH ) for the amount of observed instability in the system. This parameter can be set in
the range of 0–2000 and is entered as a weight value. When a new sampled weight value is acquired, the adaptive filter
compares the new value to the previous (filtered) output value.
If the difference between the new value and the previous output value is greater than the
ADTHRH parameter the adaptive filter
is reset to the new weight value.
If the difference between the new value and the previous output value is less than the
ADTHRH parameter, the two values are
averaged together using a weighted average. The weighted average is based on the amount of time the system has been
stable, and selected ADSENS sensitivity.
With the adaptive filter threshold set at zero, determine the amount of instability present. Enter this amount of weight instability
to set the threshold of the adaptive filter. The adaptive filter is set to OFF the ADTHRH parameter is set to zero.
11.7.3 Damping Filter (DMPONLY)
The damping filter is a simple filter which adjusts the amount of time it takes for a change in weight to be processed through the
scale. The DAMPVAL parameter is a time interval specified in tenths of a second (10 = 1 second). This damping value is used
to determine the amount of time it takes for the scale to reach its final weight output. When DAMPVAL is set to ten, a transition
from 0 lb to 500 lb on the scale takes one second. The closer the weight gets to its final amount, the slower the weight changes
on the display.
