Appendix E - Spindle Entry Codes and Range Coefficients
The range coefficient is a convenient tool for quickly determining the maximum viscosity that
can be measured with a specific spindle/speed combination. Identify the spindle in use and the
torque range (LV, RV, HA, HB) of the Viscometer/Rheometer. Look up the Range Coefficient in
the following table. Divide the Range Coefficient by the spindle speed to determine the maximum
viscosity in centipoise that can be measured.
E.g. RV Viscometer with RV3 spindle: Range Coefficient is 100,000. At 50 RPM, the maximum
viscosity that can be measured is 100,000/50 or 2,000 cP.
The Entry Code is the two digit number used to identify the spindle in use when operating a
standard digital Viscometer/Rheometer.
