Brookfield DV-III Rheometer - Manual (Page 26)

APPENDIX A - Cone/Plate Rheometer Set-Up
The Cone/Plate (C/P) version of the DV-III Rheometer uses the same operating instruction procedures
as described in this manual. However, the gap between the cone and the plate must be mechanically
adjusted before measurements are made. This is done by moving the plate (built into the sample cup,
Part No. CP-44Y) up towards the cone until two small pins (one in the cone, the second mounted on the
plate) contact slightly, and then by separating (lowering) the plate 0.0005inch (0.013mm).
Note that the Cone/Plate Rheometer requires the use of a circulating temperature bath controlling
temperature to within (+/-) 0.1
°
C. The bath is connected to the ports on the CP-44Y sample cup.
The following example assumes that the C/P Rheometer is set up on the DVP-2Y stand and has been
zeroed and leveled with no cone attached. Cone CP-40 is used in the illustrations. The water bath is on,
set at the same test temperature that you will use when measuring the viscosity of your sample and is
connected to the sample cup (Figure A1). Allow enough time for the bath to reach the test temperature.
The Rheometer should be set at 10 RPM with motor OFF.
