5.8 “Geiger Counter” Menu [GEIG]
The “Geiger Counter” function enables the ParticleScan to emit an audible signal at intervals which are proportionate to
the number of particles (≥0.3 µm) that are detected in a period of one second. The
“Geiger Counter” Menu allows the user to choose from 10 sensitivity levels. The most
sensitive setting is 1, which means that for each particle counted in a period of one
second, the ParticleScan will generate one beep. The least sensitive setting is 10,
which means that for every 500 particles counted in a one-second period, one beep
will be generated.
To change the “Geiger Counter” setting, press the Menu key until you reach the Menu
display starting with [GEIG]. Press and hold the ENTER key for two seconds until the
current setting starts to flash. Use the UP or DOWN key to select the desired setting.
[OFF] means that the ”Geiger Counter” function is disabled. 1 to 10 represent the
available sensitivity settings (see table). Use the UP or DOWN key to select the
desired setting. Confirm your selection by pressing and holding the ENTER key for
two seconds until the selection stops flashing.
Note: Whereas the ParticleScan display updates particle concentration after 6 sec-
onds (default), the “Geiger Counter” issues a beep based on the number of particles sampled in one second. Due to the
shorter sampling period, the “Geiger Counter” reacts more quickly to changes in particle concentrations than the display.

5.6 Sample Time Menu [SAti]
The Sample Time Menu allows the user to select the sampling period (in terms of seconds) for particle sampling. The
default setting is 6 seconds, which means that the ParticleScan will sample and display a new particle concentration
measurement after 6 seconds.The minimum time period that can be set is 1 second and the maximum update period is
600 seconds (10 minutes).
To change the sample time period, press and hold the ENTER key for two seconds until the currently set time period
starts to flash. Use the UP or DOWN key to select the desired setting. Confirm your selection by pressing and holding the
ENTER key for two seconds until the selection stops flashing.

5.7 Sample Repeat Menu [SAr]
The Sample Repeat Menu allows the user to have the ParticleScan take just one sample [OncE] and hold the result or take
continuous samples [Cont] until the sampling is stopped. The default setting is continuous.
To change the Sample Repeat setting, press and hold the ENTER key for two seconds until the current setting starts to
flash. Use the UP or DOWN key to select the desired setting. Confirm your selection by pressing and holding the ENTER
key for two seconds until the selection stops flashing.
5.9 Alarm Menu [A]
The Alarm Menu allows the user to set audio alarm thresholds for every one of the six cumulative (≥0.3, ≥0.5, ≥0.7, ≥1.0,
≥2.0, ≥5.0 microns) and five differential (0.3–0.5, 0.5–0.7, 0.7–1.0, 1.0–2.0, 2.0–5.0 microns) size channels. When an alarm
threshold is exceeded, a beep alarm will sound and the appropriate channel size LED will flash.
To set an alarm threshold for a channel, use the UP or DOWN key to select the size channel for which you would like to
activate the alarm. Then press the Menu key until you reach the Menu display starting with [A] for Alarm. Press and hold
the ENTER key for two seconds until [A0000000] appears. Use the UP or DOWN key to enter the first digit and/or press the
ENTER key to move one digit to the right. Once the desired threshold is entered, press and hold the ENTER key for 2 sec-
onds to confirm.
To turn off an alarm threshold, select the appropriate size channel LED with the UP or DOWN key, press the MENU key
until you reach the Menu starting with [A] , press and hold the ENTER key for two seconds until the display shows
[A0000000], with the first zero flashing. Press and hold the ENTER key for two seconds until the zero stops flashing and
switches to [A…OFF]. Your alarm threshold has now been turned off.
