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.

Scan Mode

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.
