    The accuracy of the DV-II+Pro is verified using viscosity standard fluids which are available from Brookfield Engineering Laboratories or your local Brookfield agent. Viscosity standards are Newtonian, and therefore, have the same viscosity regardless of spindle speed (or shear rate).
  • Page 67 Brookfield Viscosity Standard Fluid General Information We recommend that Brookfield Viscosity Standard Fluids be replaced on an annual basis, one year from date of initial use. These fluids are pure silicone and are not subject to change over time. However, exposure to outside contaminants through normal use requires replacement on an annual basis.

First verify the calibration of the viscometer using the standard viscometer spindles (LV1-4, RV2-7, HA2-7 and HB2-7 or cone/plate spindles) as detailed in this appendix. Second verify the calibration of the viscometer using the Thermosel.

Second verify the calibration of the viscometer using the Spiral Adapter.
  • Page 70 Notes: 1) The spindle must rotate at least five (5) times before a viscosity reading is taken. 2) The use of Brookfield Viscosity Standard fluids in the range of 5 cP to 5000 cP is recommended for cone/plate instruments.

    The current guard leg is a band of metal in the shape of the letter U with a bracket at the top that attaches to the pivot cup of a Brookfield Viscometer/Rheometer. Because it must attach to the pivot cup, the guard leg cannot be used with a Cone/Plate instrument. A guard leg is supplied with all LV and RV series instruments, but not with the HA or HB series.
