Note: Be sure that the units of the gauge are set for the same units as the material you are uploading.
If, for example, the gauge was set in U.S. Customary units (ex: 150 lb/ft3) and you were to upload the
material in SI units (2402.8 kg/m3) the gauge will notify you that the density is out of range. However, it
will continue to load the material. If you were to switch to SI units AFTER the material has been loaded,
the density would convert the 2402.8 as if it were in lb/ft3 and result in 38,489.2 kg/m3. Correct this
by deleting the material, change the units of the gauge and reload the material or by simply editing the
density in the material setup.
See Part 5 for explanations of the Material Properties.
See Part 6 for explanations of gradation and Proctor test reports.

Defining and Editing a Material
Define, Edit or Upload Material Properties
Here you may use the green up or down errors to select a new material for editing or change an existing
material. The green highlighted material is the CURRENT MATERIAL that the gauge will use when
taking readings. Prior to exiting this screen, be sure this is the material you want and the information to
the right has been verified. Press Control Menu on the Status Bar (bottom middle) to return to the Control
Menu. If the gauge is shutdown, the current material prior to shutdown will remain the current material when
started back up.
!! Note: The sum of %Greater the 3 inches, %Gravel, %Sand, and %Fines must add up to 100%. The
default values programmed in the SDG software add up to 100%. As soon as one of those values is
edited, the sum will no longer add up to 100% and an error message will be displayed, however, after the
initial error the gauge will allow you to exit and begin taking readings. THIS IS NOT RECOMMENDED
AND WILL GIVE INACCURATE RESULTS!!
!! Note that Max Dry Density and Dry Density Offset must be entered in the same units in which the
gauge is configured to output results. Example: If the gauge is configured to measure in pcf, input Max
Dry Density in pcf !!
