Light Sensor Considerations
Specifying the Source and Sensor
Using the LI-6400 8-5
Pick Source
When you press Pick Source (F1) in the Light Source Control screen, the
LightSource Selection Menu (Figure 8-2) will appear.
Edit StdFile.
This option in the Light Source Control screen opens the file /User/Configs/Light-
Sources
for editing. You would do this if you wished to add your own entries,
or modify existing entries. Note that this is NOT the method of modifying the
LED source entries. They are added via the Installation Menu.
Revert StdFile
The revert file option changes the file
/User/Configs/LightSources back to itÕs de-
fault state. The default version of this file is stored in /Sys/Lib/LightSources.
