Calibrating the USM Go 5 Operation
USM Go Rev. 10 (06/2021) 5-31
Case B: With unknown material velocity
Use the semi-automatic calibration function of the
USM Go with the functions of the function group
AUTO-
CAL for this calibration case.
You have to enter the distances (lines) of two calibration
echoes as default settings. The USM Go will then carry
out a plausibility check, calculate the material velocity
and the probe delay, and set the parameters automati-
cally if the plausibility is given. Otherwise, an error mes-
sage is given.
– Set the required display range using the function
RANGE . The two selected calibration echoes must
be displayed on the screen. Set the range so that the
second calibration echo is positioned in the right half
of the screen.
– Switch to the function group AUTOCAL .
– Enter the distances of the two calibration echoes in
S-REF 1 and S-REF 2 .
– Position the gate on the first calibration echo
( A-START ).
– Switch to the function RECORD and press a function
key.
– Press a function key again to record the first calibra-
tion echo.
– Shift the gate to the second calibration echo.
– Switch to the function RECORD again and press a
function key to record the second calibration echo.
