Communication between
Aerosol Instrument
Manager
®
Software and
the Electrostatic
Classifier Model 3080
The Aerosol Instrument Manager
®
software version 8.2 is capable of
communicating with the TSI Model 3080 Electrostatic Classifier. If
you wish to use this communication, connect the computer to the
classifier with a serial cable or USB-to-serial cable.
The software sets the sheath flow rate and bypass flow rate in the
classifier to values you select through the software. It sets the
sheath flow mode to the appropriate value (dual or single blower)
based on the selected flow rates and sets the voltage mode to
analog.
The software reads the sheath temperature and absolute pressure
from the classifier before the start of data collection for each sample
and uses those values to calculate gas viscosity and mean free
path. If the software is not connected to the classifier it will use
reference gas values that you can enter on a Properties dialog.
