Description
Note:
When a sudden change in raw data counts occurs, the response time of the filtered data
counts is determined by the time constant and may take a significant amount of time to reflect the
average raw data count value. The Fast Catch-up function initializes the filtered data counts to the
value of the raw data counts. This can currently be accomplished by changing the time constant
and setting it back to the previous value.
Dynamic tracking performs a similar function. When the dynamic tracking threshold is exceeded, a
faster time constant is used until the filtered data counts catch up to the raw data counts. The
Fast Catch-up function can be used when dynamic tracking is enabled.
