Presets and calibration
There are a number of steps to take before starting measurements:
1)
In the main window of the device, select the material of the test sample from
the list (see “The main window” section).
2)
Select the temperature of the test sample (see “The main window” section).
The speed of sound in a material is temperature dependent. Therefore, it is
necessary to try to set the temperature of the test sample as accurately as
possible so that the device takes into account the change in the speed of
sound. This is especially important for measuring the thickness of heated
samples.
ATTENTION!
When measuring the thickness of a sample with a surface temperature of more
than 80 °C, it is necessary to use the EMT40004T converter.
