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 on page 6
–
3).
To access the
% Voids
function, press

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.
