Brookfield Dial Viscometer - Manual (Page 10)

Brookfield Engineering Laboratories, Inc. Page 10 Manual No. M/85-150-P700
Remove the sample cup and attach the cone to the Viscometer (Note: left hand threads), using the spindle
wrench to hold the Viscometer shaft (Figure A2). Note: Lift up gently on the spindle wrench.
Figure A2
Attach the sample cup and swing the clip under the cup to secure it in place. Take care to avoid hitting
the cone with the cup (Figure A3). Note: Do not add test sample during the gap setting procedure.
Figure A3
Start the Viscometer running at 10 or 12 rpm. Readings of % Torque (dial reading) will be utilized for
setting the cone/plate gap. If the display reading jumps to 0.5% of scale (or higher), or will not settle to
zero (indicating that the pins on the cone and cup are hitting), unscrew the adjustment ring by turning
it to the left (clockwise as you look down on the instrument) until the reading settles at 0.0% (Figure A4).
