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:

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.
