5-20 Issue 01, 04/2005 Krautkramer USM 35X
Operation Calibrating the USM 35X
The correct calibration is confirmed by the message
“Calibration is done”.
The USM 35X will now automatically determine the
sound velocity and the probe delay and set the corre-
sponding functions accordingly. The value of the func-
tion CAL jumps back to 0.
H Note:
If the instrument is not able to carry out any valid cali-
bration on the basis of the input values and the echoes
recorded, a corresponding error message is displayed.
In that case, please check the values of your calibra-
tion lines and repeat the process of recording the cali-
bration echoes.
Example
– Enter the distances (thicknesses) of the two calibra-
tion lines S-REF1 (20 mm) and S-REF2 (40 mm).
– Position the gate on the first calibration echo.
– Press to record the first calibration echo.
