7.4 The ParticleScan Control Window
The ParticleScan control window which can be reached
via a web browser connection or a ParticleScan USB
software connection has numerous remote control and
data logging features.
7.4.1 Start/Stop Measurements
To manually start or stop a measurement, click on the
<Start> and <Stop> button. The measurement data is
displayed in six current measurement fields, after every
measurement update.
7.4.2 Sample Time
The <Sample Time> selection allows to select the
update period (in terms of seconds) for particle sam-
pling. If the setting is 6 seconds, the ParticleScan will
display a new particle concentration measurement
every 6 seconds. The time also coincides with the data
points logged.
7.4.3 Sample Repeat
The Once/Continuous selection allows the user to have
the ParticleScan take just one sample and hold the
result ([once]) or take continuous samples ([cont]) until
the sampling is stopped.
7.4.4 Measurement Units
Select one of the three measurement units: particles
per cubic meter (1000 L), particles per liter or particles
per cubic foot (cu.ft.). This can be done during or after
a measurement.
7.4.5 Count Type
Select between <Cumulative> and <Differential>. The
cumulative selection shows all the particles equal to
or larger than the selected size channel. The differential
selection shows the particles whose size lies between
two size channels. Refer to 3.2.
7.4.6 ParticleScan Display On/Off
The ParticleScan Display option allows to turn off the
display and all indicators of the ParticleScan. This may
be useful when the ParticleScan is used as a remote
sensor. Turning off the display will also save battery life
when the ParticleScan is not connected to a power
adapter.
