5. Basic Operation
The following sections describe the basic operation for the 38DL PLUS ultrasonic
thickness gage.
5.1 Setting Up the Transducer
The 38DL PLUS operates with a full line of single element and dual element
transducers. The 38DL PLUS automatically recognizes standard D79X dual element
transducers and automatically loads the appropriate predefined setup. The
predefined setup contains ultrasonic velocity for the stainless steel step block
supplied with the instrument. With dual element transducers, you need to perform a
transducer zero compensation.
For a single element transducer, or other dual element transducers, you need to
manually load an appropriate setup. The 38DL PLUS ships from the factory set up
with default conditions for the purchased transducers using an approximate sound
velocity for the stainless steel test block provided with the instrument. The default
conditions are selected to facilitate instrument usage for your applications.
To set up the transducer
1. Plug the transducer into the transducer connector(s) at the top of the 38DL PLUS
case (see Figure 5-1 on page 64). Use T/R 1 for a single element transducer.
