2) Assuming the probe menu is still displayed from the previous type selection,
use the UP and DOWN arrow keys to scroll through the sub menu items
until ZERO TRANSDUCER is highlighted.
3) Press the ENTER key to display the confirmation screen.
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 PR-8V. 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.

If the material velocity is known, the user may wish to simply enter the velocity
number into the PR-8V, rather than have the PR-8V calculate the velocity value on
using a know thickness. The steps for entering the velocity are outlined below:
