6–
TRENCH OFFSET
To use the Model 3451 in a trench or within 0.6 m (2 ft) of a large
vertical surface, first perform a
trench offset
. When a trench offset is
enabled, the gauge automatically applies a
trench density offset
to
readings of 4 in. or less, and a
trench moisture offset
to all readings.
For direct transmission measurements over 4 inches deep, only the
trench moisture offset is used. In the displays shown in this section,
TMO
refers to
trench moisture offset
;
TDO
refers to
trench density
offset
values (one for each set of detectors).
To access the trench offset function, press the
〈
Trench
〉
button on
the
Offset Menu
shown in Figure 6–1 on page 6–3. The PDA
displays the
Trench Offset Select
screen shown in Figure 6–11.
The current trench offset values are displayed in the box.
To enable the offset, press
〈
Enable
〉
. To disable the offset, press
〈
Disable
〉
. The PDA displays a confirmation message. Press the
〈
ok
〉
button to return to the
Trench Offset Select
screen.
