Brookfield DV-III Rheometer - Manual (Page 30)

- 30 -
Each of the five available cones has a specific sample volume, as shown in Table A1. Note that the correct
amount of sample fluid should cover the cone face and back up over the edge less than 1mm as shown
in (Figure A8).

Notes: a) The cup may be removed without resetting the gap.
b) Remove the spindle from the Rheometer when you clean it.
c) Reset the hit point every time the spindle is attached.

Calibration Procedure for Cone/Plate Viscometers:
1) Follow the above procedures for mechanically adjusting the setting of the cone spindle to the
plate.
2) Refer to Table A1, and determine the correct sample volume required for the selected spindle.
3) Select a viscosity standard fluid that will give viscosity readings between 10% and 100% of full
scale range. Refer to Appendix B for viscosity ranges of cone spindles.Consult with Brookfield
or an authorized dealer to determine which fluid is appropriate.
