Save Sdf - DeFelsko PosiTector RTR 3D Mode D'emploi

Save SDF

Advanced models only
Stores a Surface Data File (SDF) to the USB Drive every time a
reading is taken when selected. This provides a means to perform a
more detailed analysis of the surface using PosiSoft or third party
image rendering/analysis software.
Only a single SDF can be stored at a time. Each saved image
overwrites the previous one.
The SDF can be accessed when connected to a computer (see USB
Drive pg. 26). The SDF is stored in the root directory named with the
format: rtr_{datetime}.sdf
Optical Grade Replica Tape (pg. 12) provides higher quality SDF
surface data files than conventional Press-O-Film replica tape. This
special grade of tape is recommended when taking measurements
which will be exported as SDF images.
Below is an example of a PosiTector-generated SDF opened in
PosiSoft Desktop.
