Filtering Menu
The Filtering menu is used to configure the parameters associated with the level measurement filter. It contains the following
items:
ITEM FUNCTION
Dyn Track Shows the current state of the dynamic tracking filter (enabled or disabled) and allows
the user to change the state.
Threshold Shows the maximum number of raw counts (for scintillation) or raw analog value (for
ion chamber) that the input can vary from the expected value without considering that
count/value potentially erroneous. Also allows user to change this number.
Walk Avg Shows the number elements to maintain and average in the walking average filter.
Also allows user to change this number.
Slope Smpls Shows the number measurements to make between each recalculation of the density
slope. Also allows user to change this number.
Noise Filter Shows the maximum number of potentially erroneous measurements in a row to
bridge before deciding that a step change has occurred in the level value. Also allows
user to change this number.
Monitor Shows the current state of the filtering mechanism.
Monitor (filter state) one of the following:
Monitor MEANING
ERROR Filter is not initialized (this state should not occur during normal operation of the
X96S Level Gage)
FILL The walking average buffer is filling.
TRACK The walking average buffer is filled and the filter is tracking changes in the level value
REFILL A step change has occurred and the walking average buffer is refilling.
