Diagnostic data

The diagnostic data is used for monitoring the status of the device. You can monitor both the
momentary status (via parameters) as well as the development over time (via a histogram func-
tion).

Measurement rate

The measurement rate is equivalent to the number of measurements per second. Example:
With a measurement rate of 500 Hz, a measurement takes place every 0.002 s (1/
500 Hz = 0.002 s). The measurement rate is useful for the following questions, among others:
How quickly can a change in distance be detected?
n
How many measurements can be performed on a static object?
n
For particularly dynamic applications, always consider the measurement rate together with the
filter settings
The measuring frequency value depends on the exposure time. The sensor automatically ad-
justs its exposure time to the measured object in order to always receive an optimum light quan-
tity and thus achieve a sufficient exposure reserve. The exposure time depends on the proper-
ties of the measured surface (color/structure, etc.) and the alignment of the sensor to the mea-
sured object. Dark measurement objects reflect less light and thus need longer exposure times
than light-colored objects, decreasing the measuring frequency. The measurement and change
of the output always take place with the same frequency.
INFO
The maximum speed for dynamic applications is limited by the measurement rate. Filter settings
do not affect the measurement rate.
