The full scale viscosity range for any DV-III Ultra model and spindle may be calculated using the
equation:
Full Scale Viscosity Range [cP] = TK ∗ SMC ∗
10,000 ______
RPM
Where:
TK = DV-III Ultra Torque Constant from Table D-2
SMC = Spindle Multiplier Constant listed in Table D-1
The Shear Rate calculation is:
Shear Rate (1/sec)
=
SRC * RPM
Where:
SRC = Shear Rate Constant from Table D-1
Using Non-standard spindles with DV-III Ultra and RHEOCALC Software
Spindle Entry 99 allows entry of spindle constants which the DV-III Ultra will use to calculate
Viscosity, Shear Rate and Shear Stress for spindles in boundary conditions other than the 600ml
beaker or specified chamber.
The spindles must conform to geometries that allow for mathematical calculations of Shear Rate
and Shear Stress i.e. coaxial cylinder.
