7. Repeat steps 5 & 6 until the known thickness value is correctly displayed.
8. Press the OK key to calculate the velocity and return to the menu screen,
or ESC to cancel the one point calibration.
9. Finally, press the MEAS key to return to the measurement screen and begin
taking readings.
NOTE: CHECK YOUR CALIBRATION! Place the transducer back on the calibration
point. The thickness reading should now match the known thickness. If the thickness is not
correct, repeat the steps above.
2.5 Coating Calibration
The TI-CMX has been preset to a default coating velocity of 0.0850 in/µsec (2159 m/sec).
This will be very close to the most common coating material velocities used in the field.
If the velocity of the coating is known, and different than the above default setting, the user
can simply enter the coating velocity into the TI-CMX. However, if the velocity is
unknown, the TI-CMX can also be calibrated to a specific coating sample/type using the
1pt calibration option in PECT (pulse-echo coating) mode, or a two point calibration is CT
(coating only) mode. For the purpose of this quick start section only the 1pt option PECT
(pulse-echo coating) mode will be covered. Refer to the calibration section of the manual
for a complete explanation on the coating calibration options. The following steps below
outline the necessary steps to either set the velocity of the coating, or perform a one point
calibration to calculate the coating velocity:
Known Coating Velocity
If the coating velocity is known, the user may wish to simply
enter the velocity number into the TI-CMX, rather than have the
TI-CMX calculate the velocity value using a known thickness on
a coating sample. The steps for entering the velocity are outlined
below:
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 CAL menu is
highlighted and displaying the submenu items.
2. Use the UP and DOWN arrow keys to scroll through the sub
menu items until COATING VEL is highlighted.
3. Press the ENTER key to display the Digits Edit Box.
4. Press the UP and DOWN arrow keys to scroll the highlighted value.
5. Press the LEFT and RIGHT arrow keys to scroll the digit locations.
6. Repeat steps 4 & 5 until the velocity number is correctly displayed.
7. Press the OK key to set the coating velocity and return to the menu screen,
or ESC to cancel entering the coating velocity.
8. Finally, press the MEAS key to return to the measurement screen and begin taking
readings

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.
13. Press the OK key to save the Setup, or ESC to cancel saving
the Setup.
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.
11.4 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".
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 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.
