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