Brookfield DV1 Viscometer - Manual (Page 32)

Brookfield Engineering Laboratories, Inc. Page 32 Manual No. M14-023
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. The temperature range of the
Sample Cup (CPE-44Y or CPE-44PY) is 0°-
100°C. Brookfield recommends a maximum
temperature of 80°C to allow for direct hand
contact for adjustment of the micrometer ring.
When using the sample cup at temperatures
near 0°C, be careful to avoid frost buildup on
the top surface of the cup; this could prevent a
proper fit with the micrometer ring. Please refer
to the bath manual for the proper selection of
bath fluid and tubing to ensure safe and proper
operation.
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.
4. With the motor off, thread the cone spindle
by using the spindle wrench to secure the
viscometer 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). There must be no
fluid in the cup.
6. Option: The sample cup is available with an
optional purge fitting. The user can connect
a dry gas line to this and put a blanket of dry
gas over the sample during measurement, if
desired.
