The full scale viscosity range for any DV-II+Pro model and spindle may be calculated using the
equation:
Full Scale Viscosity Range
[cP] = TK
*
SMC
*
10,000
RPM
where:
TK = DV-II+Pro Torque Constant from Table D2
SMC = Spindle Multiplier Constant from Table D1
The Shear Rate calculation is:
Shear Rate (
1
/
Sec
) = SRC
*
RPM
where:
SRC = Shear Rate Constant from Table D1
