Appendix D - Spindle Entry Codes and SMC/SRC Values
When using a standard Brookeld digital Viscometer or Rheometer, each spindle has a two digit
entry code which is entered via the keypad on the DV1. e entry code allows the DV1 to calculate
Viscosity, Shear Rate and Shear Stress values and can also be calculated when using coaxial cylinder
geometry (SSA, ULA, ermosel, DAA, etc.) and cone/plate geometry.
Each spindle has two constants which are used in these calculations. e Spindle Multiplier Constant
(SMC) used for viscosity and shear stress calculations, and the Shear Rate Constant (SRC), used
for shear rate and shear stress calculations. Note that where SRC = 0, no shear rate/shear stress
calculations are done and the data displayed is zero (0) for these functions.
