7.6 High Penetration Software Option
The 38DL PLUS high penetration software option coupled with low-frequency single
element transducers (down to 0.5 MHz) allows you to make thickness, material sound
velocity, and time of flight measurements, on materials such as composites, fiberglass,
plastic, rubber, and cast metals that are difficult or impossible to measure using
standard ultrasonic instruments. The M2008 [U8415001] transducer is a special low-
frequency transducer used to measure the thickness of thick fiber reinforced polymer
(FRP) and composite materials.
With a M2008 transducer only, press [2nd F], [CAL ZERO] (Do ZERO) at any time to
auto-adjust the zero offset and compensate for temperature changes in the delay line.
To use the high penetration software option with the M2008 transducer
1. Ensure that the high penetration software option is activated (see “Activating
Software Options” on page 92 for details).
2. Connect the M2008 transducer to the T/R 1 and T/R 2 connectors at the top of the
38DL PLUS.
