Now that your familiar with activating and moving amongst the tab groups, let’s have
a look at how to move around in the sub menu items as follows:
Getting Around in the Sub Menu Items
1) Use
the
UP
and
DOWN
arrow keys to scroll through the sub menu items
until the desired function is highlighted.
2) Depending on which function is highlighted, use the
LEFT
,
RIGHT
, and
Enter
keys to scroll the options or activate the
Digit Edit
and
List Box
options.
The sections to follow will provide the user with an explanation of the sub menu
functions:
3.2 Probe – Menu
Zero:
The
PVX-B
is zeroed in much the same way that a mechanical micrometer is
zeroed. If the
PVX-B
is not zeroed correctly, all of the measurements made using
the
PVX-B
may be in error by some fixed value. Refer to the section on page 29, for
an explanation of this important procedure.
Note:
This function is only used when using a contact style transducer with a pulse-
echo contact setup selected. All the other transducer types use multiple echo
modes, and the zero function is not needed.
Gain:
Increases or decreases the overall amplitude of the signal. Much like turning
the volume up or down on a stereo receiver. Refer to page 48 for further info.
AGC:
The
PVX-B
is equipped with an automatic gain control when operating in
interface-echo and echo-echo modes only. This is much like turning the volume up
or down on a stereo receiver. However, the
PVX-B
will automatically control how
much the volume is turned up or down. Alternatively, the AGC can be manually
controlled using the same procedures as GAIN described above. Refer to page 48
for further info.
