4) Press the OK key to complete the probe zero function, or ESC key to cancel
the probe zero function.
5) Remove the transducer from the probe zero disk, and proceed to the
calibration section.
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.
Known Velocity
If the material velocity is known, the user may wish to simply enter the velocity
number into the MMX-7, rather than have the MMX-7 calculate the velocity value on
using a know thickness. The steps for entering the velocity are outlined below:
Using a Known Material Velocity
1) Press the MENU key once to activate the menu items tab. Press the MENU
key multiple times to tab right and the ESC key multiple times to tab left until
the CAL menu is highlighted and displaying the submenu items.
