12.3 Recalling Stored Dual Element Transducer Setups

The 38DL PLUS allows you to store and recall setups for dual element transducers.
Stored dual element transducer setups can also include calibration information like
the velocity, the zero offset, the V-path, and the default gain. This feature makes it
easy to change between different transducer setups designed for different
applications.
Unsaved data will be lost when a different application setup is recalled. Save all
changes made to the active setup before recalling another setup.
To recall a custom dual element transducer setup
1. Press [XDCR RECALL].
2. In the menu, select CUSTOM DUAL ELEMENT.
3. In the CUSTOM DUAL ELEMENT screen, select the desired custom setup.
4. In the ACTIVE screen, review the setup parameters.
5. Press [MEAS] to return to the measurement screen with the recalled setup active.

12.4 V-Path

The V-path is the path along which the ultrasonic wave travels from one element to
the other when using a dual element transducer. Since the V-path is slightly longer
than twice the thickness, the instrument must calculate a compensation to measure
the true thickness. Using a V-path correction allows the 38DL PLUS to measure
thicknesses with the highest degree of accuracy and repeatability.
