2) Use the
keys to scroll the velocity to the known target
value.
Note:
The longer the keys are pressed and held, the faster the value will
increment/decrement.
Note:
Pressing the
key prior to pressing the
key will abort the cal
routine without saving any changes.
3) Press the
key to set the velocity value and return to the measurement
screen. The new velocity value will be shown at the top of the display.
CHECK YOUR CALIBRATION!
Place the transducer back on the calibration
point and verify the thickness. If the thickness is not correct, repeat the
steps above.
5.3 Basic Material Type
If the material velocity is unknown, a sample thickness cannot be taken directly from
the material, but the general type of material is known, selecting a basic material type
from the common material
(MATL)
list in the
ZX-2
would offer a reasonable
approximation of the thickness. There are 9 common materials and 2 user
programmable settings available. It’s important to note that these velocities will not
always be an exact representation of the material being tested. Use these values
only if a close approximation is acceptable. Follow the steps below to select a basic
material type:
Selecting a Basic Material Type
1) Press the
key to access the material list. The edit icon will be
illuminated and flashing.
