Operation of the Sensor with a PC

scanCONTROL 29xx

6.4.3 

Automatic Exposure Time Regulation

The automatic exposure time regulation facilitates the recording of the profile with optimum exposure time 
(shutter time). 
The 

Exposure time 

preset by the user is used as the starting value for the automatic exposure time regu-

lation. It should be selected so large that still valid measured values can be output at the darkest place of the 
profile. The scanCONTROL Configuration Tools program can be used to determine it. The automatic expo-
sure time regulation can also be deactivated if required.
If there is no object in the measuring range, the 

Exposure time

 stored in the shutter register of the sensor 

will be used as exposure time. This value must also ensure reliable recognition of the darkest measurement 
object.
A previous test is recommended if the target is very dark or has very high contrast. The various demonstra-
tion programs are suitable for adjusting and testing the exposure time. In doing so, it is by all means sensible 
to work with several different exposure times and to observe the effect in the diagrams.
The current exposure time can be calculated from the timestamps of the measured values. It is displayed as 

Exposure time

, see Fig. 26
