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 suffi-
cient time for the bath to reach the test tem-
perature.

3.

The Viscometer has been supplied with a
special cone spindle(s) which contains the
Electronic Gap Setting feature. The “CPE”
part number designation on the cone verifies
the Electronic Gap Setting feature. Note: The
“CPE” cone or cup cannot be used with earlier
DV-I+ 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 vis-
cometer coupling nut (see Figure A-3); gen-
tly 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). There must be no
fluid in the cup.

The viscosity of “electrically conductive” flu-
ids may be affected if readings are taken with
the Electronic Gap Setting feature “on”. Be sure
to shut the feature “off” before taking readings!
