Instrument overview
The CANNON® Mini-Rotary Viscometer is designed for precision
control of temperature over time, enabling accurate yield stress and
viscosity measurement of oil samples in conformance with ASTM D
3829, ASTM D 4684, ASTM D 6821 and ASTM D 6896 test methods.
Test procedure Oil samples placed in the CMRV-5000 viscometric cells are heated and
cooled at a predetermined rate according to a user-specified cooling
profile. The cooling profile parameters are downloaded to the CMRV-
5000 onboard memory via a serial interface with the host computer. The
CMRV-5000 then uses this profile to control the rate of temperature
change, independent of the host computer.
All three methods specify that the samples be initially heated to ensure
that all components of the sample are released into solution. The samples
are then slowly cooled to the test temperature using the user-selected
temperature profile and maintained at test temperature for a specified
soak period. Following the soak period, apparent viscosity (and yield
stress if applicable) for each sample is determined by applying a constant
torque to, and measuring the rotational speed of, a cylindrical rotor
which has been immersed in the sample.
The time required for completion of the ASTM D 3829 test cycle is
approximately 19 hours. The time required for completion of the ASTM
D 4684 (TP-1, two-day) test is 45½ to 53½ hours. The time required for
completion of the ASTM D 6821 test cycle is approximately 18 hours.
The time required for completion of the ASTM D 6986 test cycle is
approximately 43½ to 53½ hours.
NOTE See Chapter 10 for additional information on the ASTM procedures.

CHAPTER
3 CMRV-5000 APPARATUS
DESCRIPTION
CMRV-5000 unit/accessories
The CMRV-5000 unit
is comprised of a
head unit and Con-
troller. The head unit
contains an alumi-
num block with a
heater for warming
and thermoelectric
modules for cooling.
Five viscometric
cells are closely
fitted into the holes
in the block (see
photo). There are
also two thermometer
wells in the block.
The Controller
contains the micro-
processor, power
supply and related
electronics.
CMRV-5000 with removable cell
Viscometers (5) Each viscometer consists of a removeable aluminum cell with a remov-
able rotor resting in a brass fitting at the base of the cell. The rotor is
attached to a rotor shaft with a pivot point at the bottom.
Lower rotor bearing The lower rotor bearing consists of the rotor pivot point and fitting
mating conical depression at the bottom of the cell. The standard rotor
composition is hardened stainless steel. The drive line rotor composition
is Delrin® (NOTE: The drive line rotors/pins/weights must be purchased
separately from CANNON®.)
CMRV rotors

Version 1.0b—August, 2011; CANNON® Instrument Company
2139 High Tech Road • State College, PA • 16803 • USA
Upper rotor bearing The upper bearing consists of a brass insert at the top of the rotor shaft
with a 1.2 mm hole on the shaft axis. A cylindrical rotor pin is inserted
through the upper bearing plate about one or two millimeters into the
hole on the shaft axis.
Rotor crossbar The rotor crossbar is used to
hold the loop at the end of the
thread. It also serves as an
indicator for (optional) manual
timing of rotor rotation, and
engages the rotor locking pin
through the cooling cycle.
Rotor lockingpins The rotor locking pins are used
to prevent unwanted rotor
rotation. When the locking pin
is lowered over the rotor
crossbar (see photo), rotation is
prevented. When the pins are in
the raised (detent) position, the
rotors are free to rotate.
Pulley-wheel assembly
The pulley-wheel
assembly consists of a
timing wheel with a
digital-optical sensor
permitting precise
measurement of the
wheel rotation. The
pulley-wheel base is
designed to be fitted to
the CMRV-5000 slide
Rotor with rotor locking pin in place
track adjacent to the
viscometric cells. The
probe cable is con-
CMRV-5000pulley-wheelassemblyonslide
track
nected to the jack on the front of the CMRV-5000 housing.
Slide track The pulley-wheel assembly is designed to interlock with the pulley-
wheel slide track and move laterally so it can be aligned with the scored
marks on the track opposite each of the rotor shafts.
Winding thread The thread used for CMRV-5000 testing is a single, nonelastic strand of
70 cm (28") winding thread of silk, cotton, or similar material (Coats
North America or comparable brand, 0.1 mm radius) with a loop on one
end. One end is wound around the CMRV-5000 rotor. The other end of
the thread is tied to a small rigid plastic ring from which the test weight
may be suspended.
Hook-weights
Hook-weights are hung on the plastic ring at the free end of the thread to
apply the required force to the rotor during yield stress and viscosity
measurements. Nine disk weights, one hook-cage, and one larger hook-

weight are provided. Weights vary depending
on the ASTM Method used for testing.
Temperature probe CMRV-5000 block temperature is detected by
a 3k-ohm temperature probe, which must be
seated securely in the thermistor aperture at
the side of the CMRV housing and plugged
into the electronic chassis.
Thermometers The CMRV-5000 unit is shipped from CAN-
NON® with two thermometers to be used to
check the temperature of the block.
The long thermometer used for the probe
and cell calibrations is a PRINCO mer-
cury-thallium calibrated thermometer with
Hook-weights
a range of -46°C to +30°C in .2°C increments and an accuracy of ±
0.01°C below 20°C.
The shorter, high-temperature uncalibrated thermometer has a range
of 0°C to 105°C in 1°C increments with an accuracy of ± 1°C.
NOTE If a thermometer is removedfrom
the CMRV-5000 when the unit is
cooling, plug the thermometer
aperture in the Plexiglas®
cover to
prevent ice formation around the
rotors.
Cell caps Cell caps are used to enhance
temperature control and prevent
condensation in the CMRV cells
during the cooling phase of the
temperature profile.

The instructions in this chapter are for setting up a single CMRV-5000. For
additional information on multi-unit configurations, see APPENDIX D.
Physical placement
CAUTION The CMRV instrument is quite heavy. To avoid injury, obtain necessary
assistance when lifting and moving instrument components.
Placement Place the CMRV-5000 Controller/base unit on a stable laboratory bench
within 10 mm of the front edge. This orientation will allow the weight
suspended from the head unit pulley-wheel assembly to clear the edge of
the table during viscosity and yield stress tests. Place the head unit on top
of the Controller, and position the head unit so the rubber "feet" fit in the
corresponding holes in the top of the Controller chassis. Allow 30.5 cm
(12") of clearance to the back and sides of the units.
Thermometer placement When in use, the larger thermometer (-46°C to +30°C) is placed in the
thermometer well on the left side of the CMRV-5000 unit (seen from the
front).
When in use, the smaller thermometer (0°C to 105°C) is placed in the
thermometer well on the right side of the CMRV-5000 unit (as seen from the
front).
NOTE If the mercury column in a thermometer has separated during shipment,
read the instructions included in APPENDIX C. These instructions offer
several methods for joining separated mercurycolumns.
Electrical /serial connections
Attach the DC power cable to the OUTPUT connector on the Controller
and the INPUT connector on the head unit. Twist the connectors clock-
wise to secure the power cable connections.
Make sure the CMRV-5000 power switch on the Controller is in the OFF
position; then insert the power cable into the mating receptacle on the
Controller rear panel (see diagram, next page).
