Operation of the Measuring System with a PC

scanCONTROL 25xx

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 guarantee reliable recognition of the darkest measure-

ment 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
