NOTE:

Pressing the

key prior to pressing the

key will abort to the

measurement screen

without saving changes.

8.2 High Speed Scan

The High Speed Scan feature of the TI-007X increases the overall repetition rate to a
maximum of 140Hz with a high speed screen refresh rate of 25 times a second. This
allows for making scanned passes over an arbitrary length of the test material, while still
maintaining a reasonable representation of thickness over the area or region scanned.

The procedure to use the scan feature is outlined below:

1. Press the

key to toggle

SCAN

on/off. The display will briefly display the

status

and return to the measurement scree..

8.3 Alarm

The Alarm feature of the TI-007X provides a method of setting tolerances, or limits,
for a particular application requirement. This feature may be used for a variety of
applications to verify the material thickness is within the manufacturer specifications.
The settings available are ON/OFF/BEEP, where beep enables the audible beeper.
Both the on and beep settings will illuminate the led alarm lights above the keys on
the keypad. There are two limit values HI/LO, that can be set according to specified
tolerances.

The procedure to use the alarm 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
ALRM feature is being displayed.

3. Press the

key to edit the alarm status. The edit icon will be illuminated and

flashing.

4. Use the

and

keys to toggle alarm on/off/beep.

5. When the desired ALRM status is displayed, press the

key to set the status

and edit the LO limit option.

6. Use the

and

keys to scroll the LO limit value to the target

value.

Note

: Pressing the

key prior to pressing the

key will abort to the

measurement screen without saving changes to the LO limit value.
