Aerosol Inlet/Cyclone
The aerosol inlet is designed for use with the supplied Cyclone
(Model 1031083). The cyclone removes large particles outside the
instrument measurement range that can cause counting errors. For remote
sampling, tubing may be attached to the cyclone inlet. The cyclone is
attached to the aerosol inlet using a Swagelok
®
-type union connector,
which is supplied.
Aerosol Outlet
Sampled aerosol flow is filtered and exhausted at this port.
AC Connector and Switch
Plug the supplied AC cable into this receptacle. The instrument power
switch is integrated into this AC connector at the top of the receptacle.
RS-232 Serial Connection
The data connection for the EEPS spectrometer is a standard RS-232
serial port connection that allows communications between the system
computer and the Model 3090 for control by the EEPS software
(Figure 1-4). Serial commands are sent to and from the computer to collect
instrument status information and provide control functions.
Appendix D
provides information that may be useful for developing custom
software. The appendix provides a description of the basic serial data
communication commands. (In some cases serial commands may be used
for troubleshooting.)
