by calculating delay in prism which sizes constantly decrease as the transducer wears
out. When this item is selected, the Device window will be as follows:
Sensor calibration
When the Calibration text appears on the screen, put the sensor on the
calibration sample coated with contact liquid. Then, the Device will calculate the delay
in prism and will measure the thickness of this sample as 3 mm.
Thickness This calibration enables to calculate the acoustic speed in
automatic mode according to the known thickness. To calibrate according to the known
thickness, place the sensor on the object with known thickness and select this
calibration item. Then, the following window will display:
Calibration according to known thickness
