CALIBRATING THE GAUGE
Calibration on a Test Sample
If possible : the Gauge should always be calibrated on the actual Material-under-Test,
or on a measured test-sample of the same material
Calibration by Sound Velocity
If there is no test-sample available : the Gauge can be calibrated by setting the value of
Sound Velocity directly
Calibration by Named Material
CygLink provides a list of commonly-used engineering materials – Calibration can be
achieved by selecting from this list
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, page 43
Calibration on a Test Sample
Turn the Gauge on as normal, and place the Probe on the measured test-sample, and
ensure that a stable reading is being obtained
Calibration
Click on the
Move the slider until the displayed reading is exactly the same as the known thickness
of the test-sample: the Gauge is now Calibrated
