Prior to measuring, remove all the dust, dirt, rusting and grease if possible from the material that is
to be measured.

4. Measurement Tips
When measuring cylindrical parts to determine the thickness of the pipe wall, it will be important
to maintain proper orientation of the transducer. If the diameter of the pipe is larger than
approximately 4 inches, measurements should be made with the transducer oriented so that the
center metal line on the tip is perpendicular (at right angle) to long axis of the pipe. For smaller pipe
diameters, two measurements should be performed, one with the center metal line perpendicular,
and another with the center line 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.
Measuring uneven and irregular surfaces will result in errors. Try to smooth out the surface if
possible by milling or polishing or using a coupling agent that has higher viscosity.
Texture that is created during the machining process of a material can also cause reading errors.
Adjust the angle of attack between the transducer and the uneven surface might provide more
accurate readings. There is a metal center piece on the tip of the transducer. This tip can be angled so
that the center metal line is crossing your uneven portion.
For measuring materials that are odd shaped or complex shapes refer to point 4.4 above. (Take the
smaller of the readings as this will be the most accurate reading.
To get the accurate results, the surface being measured must have the measuring side parallel to
the opposite side. Meaning, if the opposite side is uneven it will be more likely to obtain an incorrect
reading.
