48iQ Instruction Manual
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
CO 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.
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. 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.
