Press
[MEAS]
to complete the calibration and return to the measurement screen.
If you turn off the instrument before pressing
[MEAS]
, the velocity will not be
updated to the new value. Instead, the instrument retains the previous value.
When the 45MG detects an error in the calibration procedure, it successively displays
the following messages in the help text bar before returning to the measurement
screen:
“
Potential wrong echo detected!
”
“
Invalid calibration results!
”
In such case, the velocity is not changed. The probable cause is that an incorrect
thickness value was entered, or the incorrect back-wall echo was detected.
