Dakota Ultrasonics

feature is generally used for basic “nodularity” testing, as velocity is a key part of
density for determining hardness. An example might be casting manufacturers
where the density/hardness will determine the strength of the material.
When this feature is enabled, the
ZX-5
is operating in reverse to the standard option
of the gauge. Only the ‘one point’ calibration can be used with this feature active,
and a manual or auto zero is still required. The
ZX-5
can be calibrated by entering
the known velocity or entering the know thickness of the material at a given position
on the test material. Refer to the ‘making measurements’ section on page 24 for a
complete explanation of the zero and one point calibration procedure.
The procedure to enable the velocity feature is outlined below:
Velocity Gauge
1) Press the
key to access the menu items/features.
2) Use the
keys to scroll through the items/features until the

feature is being displayed.
3) Press the

flashing.
4) Use the
keys to select the on/off option.
Note:
Pressing the
key prior to pressing the
key will abort to the
measurement screen without saving changes.
5) When the desired
VX
setting is displayed, press the
key to set the
status and return to the measurement screen.
