The Calculated Values selection on the Settings dialog (Options > Program Setup then click on Calculated Values underneath Moisture-Density in the navigation list at the dialog's left side) includes several options that affect how moisture-density test results are reported:
This selection changes the units to be used to report calculated densities, regardless of the units used to enter the compaction test data.
This selection box controls the program's rounding of calculated maximum density values. Note that the list of available rounding options changes depending upon which density units have been selected.
This selection box controls the program's rounding of calculated optimum moisture content percentages.
- Using the Test Specification editor (see this section) you can override the rounding selection on a per-test specification basis: This can be useful for setting the test results rounding selection for particular moisture-density test specifications that mandate a specific rounding procedure for test results. If your Round max. density to and Round opt. moisture to selections are not reflected in your reported test results, use the Test Specification editor to check to see if your test specification overrides the default rounding settings.
Clicking on the Edit button brings up the Moisture-Density test specification editor, covered here.
