Auto calibration
Using different probe, wear out probe and the environment temperature
will all cause measurement error, for these factors, the “Auto calibration”
function is available.
1.
Press
key, screen displays as following, ,
2.
Select “Auto Calibration”, Press “
OK
” key.
Note: During calibration, ensure the clean of the probe surface
because the attached coupling agents and other dirt will influence the
calibration accuracy. When the measuring temperature changes greatly,
it is recommended to use this function to make sure the measurement is
accuracy.

Velocity measurement
Because the work-piece is made from various materials and even the same
material with different content and processing technology, the sound
velocity will changed. And this change will cause the measuring error. If
the error is not enough to influence the measuring accuracy, it can be
neglected. Otherwise it is necessary to get the accurate sound velocity of
the work-piece to be measured. In this case, the function of velocity
measurement can be used, the usage is as follows:
