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 viscometer when you clean it.
c) Reset the hit point every time the spindle is attached.

Calibration Procedure for Cone/Plate Viscometers:

1) Follow the procedures outlined in Appendix A for mechanically adjusting the setting of the cone

to the plate.

2) Refer to Table A1, and determine the correct sample volume required for the spindle to be

utilized.

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.
