Note:
When removing the transducer, a thin film of coupling agent is occasionally
drawn between the transducer and the surface. If this is the case, the measurement is
made through this film of coupling agent, resulting in a reading that is greater or less
than it should be. This effect is obvious when one thickness value is observed while
the transducer is being used and another value is observed after the transducer is
removed. In addition, measurements through very thick resist films or coatings can
result in the resist film or coating being measured rather than the actual material. It is
the sole responsibility of the user of the instrument to use the instrument correctly and
to detect such effects.
