One Point Calibration
NOTE: Use the maximum coating sample for the one point calibration first.
1. Physically measure the thicker of the two samples of coating, as close as possible to the
maximum expected coating measurement range, using a set of calipers or a digital
micrometer.
Very Important: If coating measurements will be made with the coating applied to a
metal surface, the calibration must be done in the same manner, with the samples coupled
to a metal surface. However, if the coating will be measured as a stand alone material, the
calibration must be performed the same way.
2 Apply a drop of couplant on the transducer and place the transducer in steady contact
with the thicker of the two coating and samples fist. Be sure that the reading is stable
and the repeatability 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 COATING 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.
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 coating one point calibration.
9. Finally, press the MEAS key to return to the measurement screen and begin taking
readings.
Two Point Calibration
NOTE: Use the minimum coating sample for the two point calibration.
1. Physically measure the thinnest of the two samples of the
coating, as close as possible to the minimum expected coating
measurement range, using a set of calipers or a digital
micrometer.
Very Important: If coating measurements will be made with the
coating applied to a metal surface, the calibration must be done in
the same manner, with the samples coupled to a metal surface.
However, if the coating will be measured as a stand alone material,
the calibration must be performed the same way.

DEFAULT SETUP: Loads a basic default setup. Use only as a last resort when the setu
in the TI-CMX have been corrupted and a computer is not accessible. Refer to section 1
for further info.
LANGUAGE: Provides the user the ability to select different languages for the TI-CMX
Refer to section 11.4 for further info.
3.7 UTIL (utilities) – Menu
SCAN MODE: This function enables a hi speed scan mode
that increases the overall sample rate from 65 to 200 measure-
ments per second, depending on the current measurement
mode used. Refer to section 10.2 for further info.
ALARM: Toggles alarm mode on, off, or audible. Refer to
section 10.3 for further info.
ALARM HIGH: Gives the user the ability to set the HI limit
parameter. If the measurement exceeds this value, a red light
will illuminate and sound the internal beeper. Refer to section
10.1 for further info.
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 wi
display ± the difference from the nominal value entered. Refer to section 10.2 for furthe
info.
3.8 XFER (transfer) – Menu
BACKUP SETUPS: Enables the user the ability to backup the
setups currently stored in the TI-CMX to a PC via RS232 port.
Refer the help section of the TI-CMX Datacomm software for
a complete electronic manual.
RESTORE SETUPS: Enables the user the ability to restore the setups currently saved
on a PC to an TI-CMX via RS232 port. Refer the help section of the TI-CMX Datacomm
software for a complete electronic manual.
ABOUT: Provides the user with Dakota Ultrasonics contact information and the TI-CM
software version. Refer the Dakota Ultrasonics web site for information on the latest
firmware versions available for download.
3.9 CLR (clear) Key
The CLR key is used to backspace when entering alpha characters in various
save/name modes.
3.10 MEAS (measurement mode) Key
The MEAS key puts the TI-CMX into it's primary mode of operation. In this
mode, the user has a complete view of the LCD.
