ALARM LOW: Gives the user the ability to set the LO limit parameter. If the measure-
ment falls below this value, a red light will illuminate and sound the internal beeper.
Refer to section 11.4 for further info.
DIFFERENTIAL: Gives the user the ability to set a nominal value and the TI-CMX
will display ± the difference from the nominal value entered. Refer to section 10.2 for
further info.

10.0 ADDITIONAL FEATURES OF THE TI-CMX
10.1 High Speed Scan
The High Speed Scan feature of the TI-CMX increases the overall repetition rate to a
maximum of 140Hz with a high speed screen refresh rate of 25 times a second. This
feature enables a user to make scanned passes over an arbitrary length of the test mate-
rial, while still maintaining a reasonable representation of thickness over the scanned
area or region. This feature can be used in conjunction with High and Low alarm limits
features
to dynamically keep track of both values. The feature is typically used to provide a bet-
ter representation of the area scanned, by taking more readings at a faster rate repetition
rate.
The procedure to use the SCAN MODE feature is outlined below:
Using the Scan Mode
1. Press the MENU key once to activate the menu items tab.
Press the MENU key multiple times to tab right and the ESC
key multiple times to tab left until the UTIL menu is highlighted
and displaying the submenu items.
2. Use the UP and DOWN arrow keys to scroll through the sub
menu items until SCAN MODE is highlighted.
3. Use the LEFT and RIGHT arrow keys to toggle the
SCAN MODE on/off.
4. Press the MEAS key to return to the measurement screen.
10.2 Alarm Mode
The Alarm Mode feature of the TI-CMX provides the user with a method of setting tol-
erances, or limits, for a particular application requirement. This feature may be used for
a variety of applications to verify the material is within the manufacturer specifications.
There are two limits, or alarm values, that can be setup in the TI-CMX – ALARM LOW
and ALARM HIGH limits. However, the user may choose to activate and utilize only
one of the limit values, depending on their specific application requirements. The proce-
dures to use the ALARM MODE feature are outlined below:
Toggle Alarm (on/off)
1. Press the MENU key once to activate the menu items tab.
Press the MENU key multiple times to tab right, and the
ESC key multiple times to tab left, until the UTIL menu is
highlighted and displaying the submenu items.
2. Use the UP and DOWN arrow keys to scroll through the
sub menu items until ALARM is highlighted.
3. Use the LEFT and RIGHT arrow keys to toggle the
ALARM on/off/audible.
4. Continue on to the next section “Setting the Alarm Low
Limit”.
