The Sonic
®
1200S/HR is now calibrated for 10 inches of steel at full screen range with each
major graticule division equal to 1 inch.
Different materials will have different velocity, attenuation, and noise characteristics. The best
accuracy will be 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).

Alternate Calibration Method - Multiple Echo, 1” - 10”
Steel
The multiple echo calibration method can be used with the dual transducer. This method is
especially useful if there is only one known thickness available.
For example, using only a 1 inch steel block (B1 Block), calibration of 1 to 10 inches or more
