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
O

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 10 seconds for averaging times between 10 and 300
seconds. For averaging times of 1, 2, and 5 seconds, the front panel display
and analog outputs are updated every second. An averaging time of 10
seconds, for example, means that the average concentration of the last 10
seconds will be displayed every 10 seconds. An averaging time of 300
seconds means that the moving average concentration of the last 300
seconds will be 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. ▲
