IMPORTANT
If you turn off the instrument before pressing [MEAS], the velocity is not updated to
the new value; instead the instrument retains the previous value.
NOTE
When the 38DL PLUS 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 this case, the velocity is not changed. The probable case is that an incorrect
thickness value was entered.
