How Do I Set Up A Bostwick Consistometer?

We get the same two questions almost every week about the CSC Bostwick Consistometer:

             1) What angle do I use to set it up?

             2) How do I level the Consistometer?

The principle of the CSC Bostwick Consistometer is based on the slump cone. In this procedure, a cone is filled with the material to be tested. It is then set on a level surface with the open area facing downward. The cone is pulled away and after a fixed time, the amount that the material slumped is measured.  The thicker the material, the less slumping occurs.
