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 Coeffecient 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.
