If the Sequoia USB cable is not available you can still use the
software via any RS232 connection to the PC. You will need to
power the instrument separately. See Appendix A for wiring
instructions.
Should you have more than one ABS instrument plugged into
your computer, the software will interface with the first
instrument it finds while searching your computer
’s ports. To
change to a different port, see the ‘Settings/Tools’ section on
page 26. You may also open several instances of the LISST-
ABS program to view data from multiple instruments.
Sampling Parameters
Just below the concentration plot, you have the ability to adjust
the number of measurements to average per data point. The
ABS samples once per second (1 hz), so this number will also
represent the amount of time, in seconds, between each data
point. For example, if you set the measurement average to 10,
the ABS would collect 10 measurements over a period of 10
seconds. The software then averages the 10 samples together
and displays the resulting concentration on the screen. If you do
not want any averaging of the ABS output, simply set the
measurement average to 1.
