5.3 Performing measurements
5.3.1 freehand measurements
Photo-thermal measuring processes are non-contact thus non-destructive.
While performing a freehand thickness measurement it is important to keep the correct working
distance to the object. The LED-pointer helps to achieve this. The pointer consists of three on the
sensor positioned LEDs. When the three LED pointers combine into one point on the object the
correct distance is achieved and a measurement can be performed.
5.3.2 Measurements with distance cap
Generally, the use of a distance cap (Art. No LD5852, to be ordered separately) is recommended
for touch-sensitive materials. This makes it possible to maintain an accurate working distance
without the risk of touching an object.
5.3.3 Measurements with Tripod
for the contactless measurement of small parts and geometries, we recommend using a tripod.
