Edge triggering
with rising or falling edge.
Starts the measured value acquisition as soon as the select-
ed edge is detected at the trigger input. The sensor outputs
the specified number of measured values when the triggering
condition is met.
Value range of 1 ... 2.147.483.646.
The pulse duration must be at least 2 ms.

Software triggering.
The measured value acquisition is triggered by the command
TRIGGERSW
. After the trigger
event, the sensor outputs the previously defined number of measured values or starts continuous measured value
output. The measured value output can also be stopped using a command.
6.5.2
Triggering Measured Value Acquisition
Measured value acquisition triggering processes measurements that are taken after the trigger event. Previously ac-
quired measured values are discarded. Acquisition triggering therefore has a direct impact on the further processing of
measured values. The sensor corrects errors internally based on the settings in the saved configurations. In the case of
moving targets and data acquisition triggering, Micro-Epsilon recommends the Auto and Fast modes.
6.5.3
Triggering Measured Value Output
The measured values are computed continuously and independently of the trigger event. A trigger event merely triggers
output of the values via the RS422 interface.

Acquisition triggering requires data acquisition to be active in the sensor.
