3. Measurement tips
1). Cleaning surface
Before measuring, the dust, dirt, rusting and grease etc
that adheres on the hardware/workpiece must be removed
off and cleaned.
2). Decreasing the roughness of surface
Too rough surface may result in measure error/ fault
reading. Please try to make the surface smooth by milling,
polishing, filling or using high viscosity coupling agent.
3). Rough machining surface
The regular tiny texture/slots resulting form rough mach-
ining process may cause error, and the compensation
method is the same as in 3.2, adjusting the angle between
the crosstalk segregating board of the transducer a metal
membrane crossing the detector bottom centre and linear
texture/slots (parallel or vertically) may also get a better
result.
4). Measuring pipe and tubing
When measuring cylindrical parts to determine the thick-
ness of the pipe wall, orientation of the transducers is
important. If the diameter of the pipe is large than appro-
ximately 4 inches, measurements should be made with
the transducer oriented so that the gap in the wearface is
perpendicular (at right angle) to long axis of the pipe.
For smaller pipe diameters, two measurements should
be performed, one with the wearface gap perpendicular,
another with the gap parallel to the long axis of the pipe.
The smaller of the two displayed values should then be
taken as the thickness at that point.
5). Complex shape material
For complex shape material measurement, please refer to
the 3.4, the smaller of the two reading should then be taken
as the thickness.
