17. Nomograph
The Nomograph function allows for measurements of thin
overlay density on asphalt or concrete. Do not use this mode
for asphalt on asphalt or asphalt on concrete surfaces. The use
of regular BS mode will produce more repeatable results on
asphalt and asphalt on concrete projects. Since the density
variation between the top and bottom material for asphalt on
asphalt and asphalt on concrete pavements are minimal, use
of the Nomograph mode does not guarantee more accurate
results. The influence from the bottom material is masked by the
top material density and the results of the Nomograph mode
and BS mode will not be different. Only use the Nomograph
mode for parking lots or projects with asphalt on top and soil or
aggregate sub base on the bottom. Under these conditions,
Nomograph mode results will be more accurate than the BS
mode of the gauge.
