Trigger mode

The Trigger mode function controls the acquisition of the measured values and thus also the

measurement frequency. The parameter settings offer you a choice between the Free Running

and Interval trigger modes.

Free Running trigger mode

The sensor measures constantly and at the highest possible measurement frequency.

The maximum measurement frequency varies depending on the characteristics of the mea-

surement object (or the exposure time). Example: Dark measurement objects (longer expo-

sure time) result in a lower measurement frequency than light-colored measurement ob-

jects.

The maximum measurement frequency is independent of the selected filter settings, since

measurement and processing of data proceed simultaneously.

Purpose/application: The Free Running trigger mode can be used in most applications (fac-

tory setting). The fastest possible recording of measurement results ensures a larger

amount of data.

Interval trigger mode

The sensor measures with a constant time interval (adjustable in µs).

Observe the maximum possible measurement frequency in the Interval mode as well. If the

maximum possible measurement frequency is exceeded, the performance can worsen.

Therefore:

▪ Measure the maximum possible measurement frequency in the Free Running mode.

▪ Calculate the minimum time interval as follows:

min. time interval = 1/max. measurement frequency

Purpose/application: Use with dynamic applications (e.g. measurement objects on a con-

veyor belt) to detect all measurement objects.
