2. Detailed Commands Description
2.1 CTN Command
This command lets the sensor exit any of the above trigger modes and returns to freerun.
No parameters are needed, so the syntax is just $CTN.
2.2 DRK Command
This command lets the sensor acquire a background spectrum that the incoming spectra will
be corrected for during normal operation. The acquisition of this background will take about
one second. The resulting background spectrum will be saved in the internal non-volatile
memory.
This command does not take any parameters, so the syntax is just $DRK.
It is important to remove any object within the measuring range before applying
the command.
The command response contains a number which is a measure of the background intensity. A
high background intensity can be related to e. g. stray light.
Command syntax:
