3. 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 PRB menu is
highlighted and displaying the submenu items.
4. Press the UP and DOWN arrow keys to scroll through the
sub menu items until ZERO PROBE is highlighted.
5. Press the ENTER key to display the confirmation screen.
6. If a coating transducer was identified use the UP and
DOWN arrow keys to toggle coating on/off.
7. Press the OK key to complete the probe zero function, or
ESC key to cancel the probe zero function.
8. Remove the transducer from the probe zero disk, and
proceed to the calibration section.
NOTE: The value that is displayed will change depending on
the current velocity setting in the TI-CMXDL. Disregard the
number that is displayed. It is not important. What is important is
accurately performing the steps outlined above to insure
reliability of the probe zero calculation.
One Point Material Calibration
For the purposes of this quick start section, we’ll only be covering the most common on
point calibration option to determine the sound velocity of the test material. It would be
very handy to carry a set of mechanical calipers to use in conjunction with the TI-CMXD
for calibration in the field:
NOTE: Be sure that the probe zero procedure has been
performed prior to performing this calibration procedure.
1. Physically measure an exact sample of the material or a
location directly on the material to be measured using a
set of calipers or a digital micrometer.
2. Apply a drop of couplant on the transducer and place the
transducer in steady contact with the sample or actual test
material. Be sure that the reading is stable and the repeat-
ability indicator, in the top left corner of the display, is fully
lit and stable. 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 CAL
menu is highlighted and displaying the submenu items.
3. Use the UP and DOWN arrow keys to scroll through the
sub menu items until MATL 1PT is highlighted.
4. Press the ENTER key to display the Digits Edit Box.
5. Press the UP and DOWN arrow keys to scroll the highlighted
value.
6. Press the LEFT and RIGHT arrow keys to scroll the digit
locations.

10. Press the ENTER key to activate the Setup List Box.
11. Use the UP and DOWN arrow keys to scroll through the setups
until the target location to save the Setup is highlighted.
12. Press the OK key to activate the confirmation screen.

14. Finally, press the MEAS key to return to the measurement
screen.
NOTE: The Name and Comments of the Setup can be edited at
any time by simply repeating the Save Setup routine described
above. Therefore, the Save Setup function can also be considered
an Edit Function.
12.4 Deleting a Saved Setup
This option allows a user to delete setup files that were previously saved and no longer
needed. It’s a simple feature to allow the user to do a bit of “house cleaning”.

the MENU key multiple times to tab right and the ESC key
multiple times to tab left until the SETUP menu is highlighted
and displaying the submenu items.
2. Use the UP and DOWN arrow keys to scroll through the
sub menu items until DELETE is highlighted.
3. Press the ENTER key to display the Setups List.
4. Press the UP and DOWN arrow keys to scroll to the
Setup Name.
5. When the Setup Name is highlighted, press the ENTER key
to display the confirmation screen.
6. Press the OK key to delete the Setup File.
7. Finally, press the MEAS key to
return to the measurement screen.
