Brookfield DV3T Rheometer - Manual (Page 28)

Two multi step Tests are shown below. The first test shows a three step test where each step has a
different speed with a single data point collection. The results will include three viscosity points,
one for each speed. The second test shows a two step test where the first step is a pre shear step.
The pre shear is conducted at 200 rpm for one minute and no data is collected. The second step
generates a single data point.

III.4 Selecting a Spindle/Speed
The DV3T has the capability of measuring viscosity over an extremely wide range. For example,
the DV3TRV can measure fluids within the range of 100-40,000,000 cP. This range is achieved
through the use of several spindles over many speeds. See Appendix B for details.
