Brookfield DV2+Pro Viscometer - Manual (Page 66)

Brookfield Engineering Labs., Inc. Page 66 Manual No. M03-165-F0612
A.2 Setup
1. Be sure that the Viscometer is securely mounted
to the Laboratory Stand, leveled and zeroed
with no cone or cup attached and 0% torque is
displayed.
2. Figure A-2 shows a typical water bath setup.
Connect the sample cup inlet/outlet ports to the
water bath inlet and outlet and set the bath to
the desired test temperature. Allow sufficient
time for the bath to reach the test temperature.
3. The Viscometer has been supplied with a
special cone spindle(s) which contains the
Electronic Gap Setting feature. The “CPE” or
“CPA” part number designation on the cone
spindle verifies the Electronic Gap Setting
feature.
Note: The “CPE” or “CPA” cone or cup
cannot be used with earlier DV-II+
cone/plate Viscometers (below S/
N50969) which do not have the
electronic gap setting feature.
4. With the motor off, thread the cone spindle by
using the spindle wrench to secure the viscom-
eter coupling nut (see Figure A-3); gently push
up on the coupling nut and hold this securely
with the wrench. Thread the cone spindle by
hand.
Note: Left Hand Threads.
5. Attach the cup, taking care not to hit the cone
with the cup (Figure A-4), by positioning the
cup against the mic ring and swinging the ten-
sion bar under the cup. The tension bar should
have plastic tubing in place.
