Sieve Opening Size Measurements

If you certify your sieves' opening sizes with a statistical measurement process you can use each sieve's statistically measured opening size instead of the program's default opening sizes. For example, LabSuite normally uses an opening size of 2 mm. for a #10 sieve: if your sieve's openings averages 1.994 mm. with an optical measurement device, you'll want to report the diameter of particles passing that sieve as 1.994 mm. instead of 2 mm.

To use the as-measured opening sizes for the sieves used for a particular sieve test, you'll need to enter that test's list of sieves into LabSuite's Sieve Opening Sizes database:

1. Select Options > Program Setup then click on Sieve Opening Sizes in the left-hand navigation panel.
2. If you've already entered a similar opening sizes list, you can drop down the Lists box, select your opening sizes list from the box and click on the Copy button.
   Alternatively, if you do not already have a similar opening sizes list:
   Click on the New button in the Size List box on the right side of the dialog.
3. Next, at the Name prompt, enter a unique name for your opening sizes list (i.e., not used for one of the opening sizes lists already stored in the program's database).
4. After you've entered your list name, pressing Enter brings you to the opening sizes grid: For each sieve you've measured, enter the sieve's designated size (e.g., #4 or 1.5in. or 2mm.) into the Sieve column then enter the measured sieve size in the Size, mm. column. The right-most column, labeled ID, can be used to enter a sieve tracking number or label. LabSuite doesn't use IDs: they're included as a convenience so that you can correlate a sieve to its measurement papers.

• You can list your sieves in any order (i.e., by increasing or decreasing opening size).
• Because an opening sizes list contains the measurements for a specific stack of sieves, you'll end up entering some sieves' measurements in more than one opening sizes list as they're used in different sieve stacks.
• For reference, LabSuite includes a list of its default opening sizes that you can view by selecting (Default opening sizes) from the list selection box. This list may not be edited.
