If possible : the Gauge should always be calibrated on the actual Material-under-Test,
or on a measured test-sample of the same material
¾ Calibration by Sound Velocity
If there is no test-sample available : the Gauge can be calibrated by setting the value of
Sound Velocity directly
¾ Calibration by Named Material
CygLink provides a list of commonly-used engineering materials – Calibration can be
achieved by selecting from this list
¾ Reading Conversion - not recommended
Log Readings with the Calibration preset to Mild Steel [5920 m/s or 0.2332 in/us], and
then later to use a Conversion FactorSee: Reading Conversion
