A-Scan Range Setting (A-SCAN RANGE)
The X-axis of the A-scan graph is ideally set to show the best
number of return echoes in the material being measured. The
gauge can automatically adjust the A-scan range using the
thickness measurement, or you can manually set the range to suit
the material thickness you expect to measure.
You can choose from the following A-Scan range values;
• AUTO The gauge automatically adjusts the A-scan range
• 15 mm (0.6”) Measuring material up to 15 mm thick
• 30 mm (1.2”) Measuring material up to 30 mm thick
• 60 mm (2.4”) Measuring material up to 60 mm thick
• 100 mm (4”) Measuring material up to 100 mm thick
• 200 mm (8”) Measuring material up to 200 mm thick
In Multiple Echo mode the A-Scan graph axis is set to 4 times the
A-Scan Range setting – this is ensure at least three back wall
echoes can be displayed. Example 15mm x 4 = 60mm.
In Single Echo mode the A-Scan graph axis is set to the A-Scan
Range setting – this is because you only need to see one back wall
echo.
The A-Scan range setting does not affect the thickness
measurement.
