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sufcient

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 veries 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.
