SOME TIPS TO FOL LOW DUR ING THE DEM ON STRA TION:
1.
Measure all test materials accurately.
2. Add the materials in the order given in the instruction.
3. Add materials to the correct test cell. If the materials are added to the
wrong test cell, the cell can be emptied using a pipet.

stirring granular materials do not press against the bottom of the cell.
This can cause small, distracting scratches on the cell.
