Synchronizing without the wizard
Synchronization can be done manually without the help of the wizard.
All parameters must be set manually. Note that some features may be set indirectly, such as the
Trigger Rate/Profile Trigger Frequency (which depend on the trigger start source).
The user is responsible for making sure of the proper timing between sensors. Refer to the
diagrams above.
Note that it is not possible to acquire simultaneously if the master profile trigger is off because a
profile trigger delay cannot be set.

Unified measurement space (UMS)
Each Z-Trak2 3D laser profiler sensor has its own measurement space; the data acquired by a unit
is relative to the unit. Combining the data from several sensors in different poses can be used to
provide a more complete representation of an object. This merging of data requires a common,
