5. Measuring technology
5.1 Cleaning surface
Before measuring, please clean any dust, dirt and rust on the object, and
remove any cover such as paint, etc. on it.
5.2 Improving requirement on roughness
Too rough surface will cause error in measurement. Before measuring,
please smooth the surface of object by grinding, polishing or filing, etc. or
use coupling agent with high viscosity for that.
5.3 Rough machined surface
The regular fine slots on rough machined (by such machines as lathe or
planer) surface will also cause error in measurement. The way for
compensating that is the same as that in 5.2. In addition, by so adjusting
the included angle between the probe’s crosstalk interlayer plate (the
metallic layer passing through the center of probe bottom) and the fine
slots of the object that the interlayer plate is perpendicular or parallel to
the fine slots, and by taking the min. value of the readouts as the
measured thickness, one can also get better results.
