Beep The Beep mode enables the AeroTrak particle counter to
operate in a “Geiger Counter” mode. As particles are
detected, a beep is emitted. The frequency of beeps
configured utilizing the alarm thresholds setting. It works on
a single bin. If you wish to beep on total particulates,
configure the unit in cumulative mode and set an alarm
threshold for the .5 channel. The alarm threshold
determines the beep frequency. The actual number of
particulates measured in the preceding 1 second will be
divided by the threshold and the corresponding number of
beeps emitted. An alarm threshold of 0 will not emit beeps.
To alarm on viable particulates, be sure that all total
particulate alarms are disabled and configure an alarm in
the viable count channels. It is configured in the same
manner described above.
