2.6 Zero Coating
To account for very slight electronic differences in transducers of the same type, frequen
and diameter, the CMX has been equipped with a “zero coating” feature. This enables t
CMX to obtain very accurate readings on coatings, eliminating potential errors incurred
from slight differences in the manufacturing processes. The procedure is outlined below
1. Press the MULTI MODE key once to activate the measurement
mode options.
2. Use the UP and DOWN arrow keys to scroll through the sub
menu items until Coating Only (CT) mode is highlighted.
3. Press the ENTER key to select the measurement mode and
return to the measurement screen.
4. Apply a drop of couplant on the transducer and place the
transducer in steady contact with the probe zero disk (battery
cover) and obtain a steady reading.
Note: The coating measurement displayed will potentially be a
value greater or less than zero.
5. 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.
6. Use the UP and DOWN arrow keys to scroll through the
sub menu items until ZERO COATING is highlighted.
7. Press the ENTER key to display the confirmation screen.
8. Press the OK key to zero the coating and return to the PRB
menu, or ESC to cancel the coating zero process.
9. Press the MULTI MODE key once to activate the measurement
mode options.
10. Use the UP and DOWN arrow keys to scroll through the sub
menu items until Coating On (PECT) is highlighted.
11. Press the ENTER key to select the measurement mode and
return to the measurement screen, and begin taking readings.
11.7 Changing the active File - Open
The user may have transferred grid/seq
templates from a PC to the TI-CMXDL,
or setup grids/seq using the TI-CMXDL
at an earlier time. The name of the cur-
rently active file is always displayed at
the top of the Grid/Seq Box in measure-
ment mode (refer to photo below). It’s
not only important to recognize what
file is currently active, but also be able
to change the active file at any time.
The following procedures outline this
process:
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 DATA menu is
highlighted and displaying the submenu items.
2. Use the UP and DOWN arrow keys to scroll through the sub
menu items until OPEN is highlighted.
3. Press the ENTER key to display the Grid/Seq List Box.
4. Use the UP and DOWN arrow keys to scroll through the grids
until the target grid is highlighted.
5. Press the ENTER key to activate the confirmation screen.
6. Press the OK key to load the file from memory.
7. Press the MEAS key to return to the measure screen.
