6.5.1 Recalling Single Element Transducer Setups
The procedure for recalling single element transducer setups is explained in “Setting
Up the Transducer” on page 51.
6.5.2 Creating Custom Single Element Transducer Setups
For more information about how to create custom single element transducer setups,
please refer to “Custom Setups for Single Element Transducers” on page 165.
6.5.3 High-Resolution Thickness
The 45MG has the ability to display thickness values with its standard resolution of
0.01 mm (or 0.001 in.), and its low resolution of 0.1 mm (or 0.01 in.). These resolutions
are adequate for most ultrasonic thickness-measurement applications.
For single element transducers, the high-resolution software option provides the
added ability to display thickness readings with a high resolution of 0.001 mm (or
0.0001 in.). High resolution is not available for all transducers and measurement
modes, and is also limited to the maximum thickness. Although the 45MG is able to
display thickness readings in high resolution, the measurement accuracy is highly
dependent on the material, geometry, surface condition, and temperature, and also
needs to be determined on a case-by-case sample evaluation basis.
High resolution is available for the following transducers and measurement
conditions:
• Single element transducer in the frequency range of 2.25 MHz to 30.0 MHz
• Thickness measurement below 100 mm (or 4.00 in.)
High resolution is not available for the following transducers or measurement
conditions:
• Dual element transducers
• Low-frequency transducers with a frequency below 2.25 MHz
• Thickness ranges over 100 mm (or 4.00 in.)
• Once activated, the high-resolution selection appears in the resolution
selection list (see “Changing the Thickness Resolution” on page 50).
