Z-Trak2 3D Profiler Sensors
Multi-sensor synchronization can be done manually. However, Z-Expert provides a Synchronization
wizard to help with the settings. All values can then be saved in a camera configuration file.
The following timing diagrams depict how some of the Multi-Sensor Sync parameters are set. The
diagrams do not include details about other synchronization settings such as exposure time or
profile rate.

Figure 21. The external/internal signal triggers the master sensor. The Group Trigger Delay value determines
the earliest time at which the sensors can start exposure. The Trigger Delay value of each sensor is different
in a sequential acquisition.

Figure 22. The external/internal signal triggers the master sensor. The Group Trigger Delay value determines
the earliest time at which the sensors can start exposure. All sensors start exposure at the same time.
