.
5) Press the
UP
and
DOWN
arrow keys to scroll the highlighted value.
6) Press the
LEFT
and
RIGHT
arrow keys to scroll the digit locations.
7) Repeat steps
5 & 6
until the known thickness value is correctly displayed.
8) Press the
OK
key to calculate the velocity and return to the menu screen, or
ESC
to cancel the one point calibration.
9) Finally, press the
MEAS
key to return to the measurement screen and begin
taking readings.
Note: CHECK YOUR CALIBRATION!
Place the transducer back on the
calibration point. The thickness reading should now match the known
thickness. If the thickness is not correct, repeat the steps above.
Basic Material Type
If the material velocity is unknown, and a sample thickness cannot be taken from the
material, the user may opt to choose a basic material type from a list with
approximate velocity values according to various material types. It’s important to
note that these velocities will not always be an exact representation of the material
