Note: The value that is displayed will change depending on the current velocity
setting in the MMX-7. Disregard the number that is displayed. It is not
important. What is important is accurately performing the steps outlined above
to insure reliability of the probe zero calculation.
One Point Material Calibration
For the purposes of this quick start section, the most common single point calibration
option will covered in this section.
Note: It would be very handy to carry a set of mechanical calipers to use in
conjunction with the MMX-7 for calibration in the field.
Note: Be sure a probe zero has been performed prior to calibration.
1) Physically measure an exact sample of the material, or a specific location
directly on the material using a set of calipers or a digital micrometer.
2) Apply a drop of couplant on the transducer and place the transducer in
steady contact with the sample or actual test material measured. Be sure
the measurement is stable and the repeatability indicator, in the top left
corner of the display, is fully lit and stable. Press the MENU key once to
