8) Press the Probe key. The display will flash 1OF2. Repeat steps 3
through 8 on the second calibration point. The MMX-6 will now
display the sound velocity value it has calculated based on the
thickness values that were entered in step 7.
9) The MMX-6 is now ready to perform measurements within this
range.
While the MMX-6 excels at making single point measurements, it is
sometimes desirable to examine a larger region, searching for the thinnest
point. The MMX-6 includes a feature, called Scan Mode, which allows it to
do just that.
In normal operation, the MMX-6 performs and displays four
measurements every second, which is quite adequate for single
measurements. In Scan Mode, however, the gauge performs sixteen
measurements every second, and displays the readings while scanning.
While the transducer is in contact with the material being measured, the
MMX-6 is keeping track of the lowest measurement it finds. The
transducer may be "scrubbed" across a surface, and any brief interruptions
in the signal will be ignored. When the transducer loses contact with the
surface for more than a second, the MMX-6 will display the smallest
measurement it found.
