Chapter 2.
3. Remove the transducer from the slider and repeat steps 1 and 2 at the three other slider positions.
4. Using a knife or a box cutter, cut holes in the damping material along the contour lines of each transducer
footprint.
IMPORTANT: The holes cut along the transducers' contour lines must be big enough to allow the entire footprint of
each transducer to sit on the pipewall without any interference from the damping material.
Note: This task may be difficult to complete because the yokes are partially in the way. If necessary, loosen the
yoke screws and move the yokes.
5. Using a solvent consistent with safety, disposal and cleaning requirements, clean the four areas of pipewall
visible through the four holes in the damping material. Make sure there are no residues of damping material on
these areas.
Note: If the faces of the transducers are not free of residues, clean them using the same solvent.
6. If you moved the yokes in step 4, remember to put them back to their exact positions before tightening the yoke
screws.
IMPORTANT: You must use the caliper again to ensure that the transducer spacing and
TAG
path are correctly set.
