2.6 Coating Calibration
The 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 CMX.
However, if the velocity is unknown, the 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
