3-14 AeroTrak
®
Portable Airborne Particle Counter
Field Description
Beep
(continued)
If multiple alarms are configured, the AeroTrak particle
counter will emit beeps only on a single channel. If multiple
alarms are configured, the AeroTrak particle counter
searches for which alarm to operating on starting with the
smallest to largest Total Particulate Channel selected
followed by the smallest to largest Viable Particulate
Channel.
Settings in the sample timing screen are ignored in beep
mode.
Example: Looking for a viable particle source that raises
above 500 count background by 10000. Configure the unit
in cumulative mode and enable the .5 viable particulate
alarm to 500. The AeroTrak particle counter will now emit a
single beep for every 500 particles. At steady state, a beep
will be emitted once per second (500/500=1). When the
source is encountered it will emit 20 beeps per second
(10,000/500) = 20. If a higher frequency is desired lower the
threshold to 200. This will result in 50 beeps per second
being emitted.
The maximum number of beeps that can be emitted per
second is 50.
