Instrument Calibration - 1 to 10” of Aluminum
Use the same procedure as the previous 0.5 inch steel test, but adjust the controls using 1-to-10
inch aluminum step blocks as the thin and thick steps. After calibrating at 1.0 inch and 10.0
inches, check at 5.0 inches for accuracy.
To select and change the following parameters, press the
menu soft key
below the selected
menu box, then rotate the SmartKnob™ or press the INC/DEC arrow keys to change the value.
The Sonic® 1200S/HR is now calibrated for 10 inches of aluminum at full screen range with
each major graticule division equal to 1 inch.
Different materials have different velocity attenuation and noise characteristics. The best
accuracy is obtained by using step blocks made from the same material as that being tested.
With practice, you may optimize the displayed ultrasonic signals by using the Gain, Damping,
Display, Frequency, and Reject control settings. The Reject setting can be used to improve the
display by eliminating small baseline signals (or noise).
An operator must recalibrate the thickness gauge when changing from IP mode to 1st back
wall reflection mode and to Multiple Echo mode to compensate for transducer offsets, surface
