Using the Tracer® TU Service Tool with a Wireless Network
Communication History tool, when interference is suspected. The Communication History tool will show
date and time when there is possible interference so the technician will know the best time to use the
Channel Quality Scan Tool to scan the area and look for channels that may have high traffic causing
interference and lost communication.
Note: Communication History Tool is only available for SC+, not SC.
The Channel Quality Scan tool can also be used as a site survey tool where a technician can go into a
building and find the best channel to use before creating the Air-fi network. And finally, it can be used as
a commissioning tool where after the installation is finished the scan data can be saved for future
reference.
Scanning and Exporting (saving) scan data
Scanning automatically starts when the Channel Quality Scan tool is opened. As the tool runs, it is
caching the data in the background to your hard drive. The Recording Data button will be red and the
timer will be counting up as an indication that it is storing the data. If it is desired to save this data,
pressing the Export button will save the data in the form of a .csv file to the hard drive. See
110. The data will be saved to this path; Documents > Tracer TU > ChannelQualityScan. The saved .csv
file can be sent to Technical Support for evaluation.

Pressing Stop will halt the scanning and allow you to Export the .csv file.
Pressing Start after the Stop button is pressed will initiate a new set of scan data. The previous data
will be lost.
The scan data cache will be flushed when the tool is closed, so export it before closing if the data is
to be saved.
