8.9 Velocity (VX)
When the velocity setting (VX) is enabled, the TI-007DLX will display will the material
velocity as the primary measurement quantity instead of dimensional thickness. The
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 TI-007DLX 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 TI-007DLX 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 15 for a complete
explanation of the zero and one point calibration procedure.
The procedure to enable the velocity feature is outlined below:
1. Press the
key to access the menu items/features.
2. Use the
and
keys to scroll through the items/features until the
VX feature isbeing displayed.
3. Press the
key to edit the setting. The edit icon will be illuminated and
flashing.
4. Use the
and
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.
8.10 Lock
The lock feature was built into the TI-007DLX for the purpose of locking the operators
out of editing any of the gauge settings, for purposes of consistency between operators.
When the lock feature is enabled, the gauge calibration functionality cannot be altered,
as well as any of the individual features in the gauge. The only keys that are always
unlocked are the power and probe zero keys, as these must remain unlocked for
measurement functionality.
The procedure to enable/disable the lock feature is outlined below:
1. With the TI-007DLX powered off, press and hold down the
key
while powering the TI-007DLX on . The lock icon will be
illuminated
on the display.
