PERCENT AIR VOIDS (SOIL MODE)
The gauge uses the specific gravity function to calculate percent air
voids and void ratio in Soil mode only. The % Voids function allows
the operator to enter the specific gravity of a material and disable or
enable the percent air voids display.
NOTE
To display percent air voids in Asphalt mode, enter a
voidless density target value (see the Target Values
section that begins on page 6–3.
To access the % Voids function, press 〈.〉 〈0〉 at the Setup menu
shown on page
5–3. The gauge displays:
The current specific gravity (default 2.70) is shown on the second
line of the display. For optimum results, use a specific gravity value
that is appropriate for the material being measured.
To enable the current specific gravity value, press 〈1〉. The
gauge enables the value, displays a brief confirmation message,
and returns to the Setup menu.
To disable the current specific gravity, press 〈2〉. The gauge
disables the value, displays a brief confirmation message, and
returns to the Setup menu.
To enter a new specific gravity value, press 〈3〉. The gauge
prompts the operator for a new specific gravity. If the displayed
specific gravity is acceptable, press the
〈ENTER/START〉 key.
To change the value, use the numeric keys to do so, then press
the
〈ENTER/START〉 key. In either case, the gauge enables the
value, displays a brief confirmation message, and returns to the
Setup menu.
