[F3] Load settings… Load in a previously saved data file and
restore the capture settings as they were when the data was saved
[F4] Save settings… This option creates one file that contains
both the current settings and the current data. The setting saved are
the same in the Save Settings option.
[F5] Print This option will create a hardcopy of the screen into IBM

Description of software for measurement of time of flight. |
This software package allows to measure
time of flight.
For each measurement it is necessary to choose reference signal and
compare it with the signal, coming from the measured medium (reflected
or transmitted through it). This allows to use this software with almost
any kind of samples, containments etc. For people using this software it
is necessary to have some knowledge about such kind of measurements,
physics of ultrasounds etc
|
|
The time of flight and thickness measurement method. |
Time of flight - Using white marker in the
upper window the interesing part of the signal should be chosen (or
signal from the first wall).
Thickness - Using blue marker in the upper window the signal from the
second wall should be choosen.
