Selecting the Measure Mode Using The Tabbed Submenu Items
Note: The E-E mode should also be selected for setting up the PVX in I-E
mode.
1) Press the MENU key once to activate the menu items tab. Press the MENU

the GATE menu is highlighted and displaying the submenu items.
2) Use the UP and DOWN arrow keys to scroll through the sub menu items

6.2 Probe zero
A probe zero should only be done if a contact style transducer is being used in pulse-
echo mode. As noted in chapter 3, the probe zero function is a very important and
necessary function that must done prior to calibration. It should also be done on a
regular basis. If the PVX is not zeroed correctly, all of the measurements taken may
be in error by some fixed value. In order to perform a probe zero, the PVX must be in
pulse-echo mode. If echo -echo mode was previously selected in the last section,
skip this section and continue on to the next. Note: If you intend to switch between
measurement modes simultaneously, setup up the PVX in pulse-echo mode, perform
the probe zero as necessary, and save the setup to one of the empty setup locations.
Once this is completed, the user can switch between modes toggling between two
setups. The following steps outline the procedure for performing a probe zero:
