Taking a Sample
The AeroTrak
®
+ A100 Portable APC is controlled
using the touch screen display. Use a plastic stylus or
your finger tip. DO NOT use sharp objects (such as a
pen point) that may damage the screen overlay.
Ad hoc samples can be taken quickly and easily when
the instrument is set to the Manual sampling mode.
Refer to the manual for testing in other modes, such
as those for classification or monitoring.

drop-down in the main status bar.
2. The currently configured sampling parameters are
shown in the lower status bar.
3. The sampling parameters can be changed by

Channels & Units, and Limits. Once the desired
settings are entered, press the OK button to save
and return to the sample screen.
