The correct integration and implementation of the measurement process is required (e.g. the handshake
to trigger a measurement). The individual measurement sequences are described in detail in chapter „12.1
Measuring procedure" on page 61 and then shown in timing diagrams.

The internal evaluation uses the results of a measurement to calculate the ideal exposure time. For this
approximately 3300-3500 cts are achieved in the measurement in order to balance out minimal fluctuations
in output.
When the exposure time is close to the optimum, i.e. there is only slight over - or underexposure, this calculation
provides reliable values.
If the exposure time is too long, several iterative steps are necessary in order to reach the optimal range.
If the exposure time is too short, there may not be enough of a signal to facilitate an evaluation. The resulting
values will then be unrealistic and the optimal setting for the exposure time incalculable.
It is therefore better to start with overly long exposure times and several steps until the optimum setting has
been determined.
