19) Apply a drop of couplant to the bolt or transducer, and attach it to one
end of the 6” calibration bar (or 3” side of glass block). Rotate the
transducer clockwise and counter clockwise applying a small amount of
pressure to eliminate any excess couplant between the transducer and
cal bar surface. Remove and replace the transducer a couple of times
in the exact same location on the cal bar, rotating it each time to obtain
the minimum value measured. Be sure to always place the transducer
in the same location. This will help to eliminate any potential
measurement errors caused by changing the sound path.
