9.3 Zero Coating
In order to account for very slight electronic differences in transducers of the same
type, frequency, and diameter, the CMX
DL+
has been equipped with a “zero coating”
feature. This enables the CMX
DL+
to obtain very accurate readings on coatings,
eliminating potential errors incurred from slight differences in the manufacturing
processes. The procedure is outlined below:
Performing a Coating Zero
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 0.
