The Averaging Time screen allows the user to choose dynamic filtering or a
manually selected (static) averaging time.
Averaging Time defines the time period (1 to 300 seconds) during which
SO
2
measurements are taken. The average concentration of the readings are
calculated for that time period. The front panel display and analog outputs
are updated every second if averaging time is greater than 1 second. An
averaging time of 10 seconds, for example, means that the average
concentration of the last 10 seconds will be displayed at each update. An
averaging time of 300 seconds means that the moving average
concentration of the last 300 seconds will be the output at each update
(every 10 seconds). Therefore, the lower the averaging time the faster the
front panel display and analog outputs respond to concentration changes.
Longer averaging times are typically used to smooth output data.
Dynamic Filtering allows for data smoothing without compromising
response time. The instrument automatically changes the averaging time
giving the user faster response times when conditions are rapidly changing;
smoother and stable readings, when conditions aren’t changing as rapidly;
and as an added bonus, it better processes spikes to minimize their impact
on the data. At the same time it will preserve the representative nature of
the filtered data to the conditions being sampled.
Note
When Dynamic Filtering is selected, the user selected Averaging
Time button is disabled.
