Material Velocity List

The Material Velocity List is a table of materials along with their

velocity of sound value. CygLink comes with a pre-defined list but

you can create your own list of materials specifically to suit your

application. This list can be send to the gauge when connected to

CygLink.

From the Menu click;

Material Velocity List

You can Edit, Add, Delete or Re-arrange the items in the list.

Note the velocity is in metric (m/s) by default. You can edit
