fluid surface, and bring the spindle to an upright position and thread onto screw.

3. Lower and center spindle in the test material (600 ml beaker) until the "meniscus" of the fluid is

at the center of the immersion groove on the spindle’s shaft.

4. To make a viscosity measurement, turn the motor switch “ON”. This energizes the viscometer

drive motor. Allow time for the indicated reading to stabilize. The time required for stabilization

will depend on the speed at which the viscometer is running and the characteristics of the sample

fluid.

When making a viscosity measurement, the reading should be noted and multiplied by the factor

appropriate to the viscometer model/spindle/speed combination being used. Refer to the table

below or to the FACTOR FINDER for calculating viscosity. For maximum accuracy, readings

below 10.0% torque (dial reading) should be avoided.

5. Turn the viscometer motor switch “OFF” when changing a spindle, changing samples, etc.

Remove spindle before cleaning.

6. The interpretation of results and the instrument’s use with non-Newtonian and thixotropic

materials is discussed in the booklet, “More Solutions to Sticky Problems” and in Appendix C.

The following tables apply to Brookfield Viscometer Models LV, RV, HA and HB with standard

spindles. They enable the user to convert the percent scale reading into a viscosity value in units of

centipoise.

To convert the viscometer dial reading to a viscosity value in units of centipoise, multiply the reading

noted on dial viscometer by the appropriate factor in the following tables.
