APPENDIX A - Cone/Plate Viscometer Set-Up

The Wells-Brookfield Dial Viscometer 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 Wells-BrookfieldCone/Plate Viscometer 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. Brookfield offers a complete line of refrigerated and non-refrigerated (tap water cooling)
circulating water baths.

The following example assumes that the C/P Viscometer is set up on the Model A laboratory stand and
has been leveled. 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 Viscometer speed
knob should be set at 10 or 12 rpm with motor OFF.
