Start Delay indicates the instrument delay before
starting a sample.
It takes approximately 10 seconds for the pump to
reach the flow set point; taking a measurement
before the pump is properly functioning may result
in a data and flow error.
Sample Time indicates the instrument sample
interval length.
Hold Time indicates the instrument delay
between samples.
Cycles is the total number of samples to collect. In
Automatic mode, a cycle value of
ā
causes the
instrument to continuously count using the settings
for Sample Time, and Hold Time until the Start/Stop
button is pressed again.
Volume sets a limit of air volume to collect for each
sample. Select the volume unit then enter a volume
value. The Sample Time will be updated
automatically to the nearest second adequate to
provide the desired volume.
7. Press the Channels tab.
8. This tab can be used to view or set the particle size for each
channel (not supported in all models), enable/disable the channel,
enable/disable alarm for each channel and set the alarm threshold
for each channel. The threshold values are expressed in the units
selected in the Count Units control. Select the appropriate
Count Units from the list.
During sampling, when a channel value exceeds the threshold value
set here, the channel data is highlighted in red on the Main screen,
an audible alarm sounds, and the alarm icon.
