CAV® 4.1 Operation Manual
Overview
CANNON® CAV 4.1 is a fully automated, single-bath, benchtop kinematic viscometer with two
14-position sample handlers for unattended ASTM D445/D446, ISP 3104/3105, and IP 71 testing. Each of
the two viscometer tubes covers a 100-fold viscosity range at values between 0.5 mm2/s (cSt) and
10,000 mm2/s (cSt) from 20 °C to 150 °C (with available options.) The CAV 4.1 combines CANNON quality
and reliability with a modern design and unique features to enhance lab productivity, reduce costs, and
improve data quality.
CANNON CAV 4.1 Single-Bath Benchtop Kinematic Viscometer comes with two 14-position sample
carousels, two viscometer tubes, one set of oil viscosity standards, a case of glass vials, a high precision
digital thermometer with probe, VISCPRO data storage/management software, a one year warranty, and
professional installation/training (within the domestic U.S.). Specify desired factory installed options and
viscometer tubes when ordering. Instrument is stand-alone but optional computer (sold separately) is
recommended for ease of calibration, connecting to LIMS (laboratory information management system),
and maintaining complete audit trail.

Notes/Cautions/Warnings
Notes, caution, and warnings are used in the manual to call an operator’s attention to important details
prior to performing a procedure or step. Read and follow these important instructions. Failure to
observe these instructions may void warranties, compromise operator safety, and/or result in damage
to the CAV 4.1.

Note:Provide more information about the content that follows.
Caution: Alerts the operator to conditions that may damage equipment.
Warning:Alerts the operator to conditions that may cause injury.
Safety Precautions
Please observe the following general safety precautions for proper and safe operation of the CAV 4.1.
•Only qualified personnel should operate the CAV 4.1.
•Make sure that you read and understand all operating instructions and safety precautions listed in
this manual before installing or operating your unit. Direct questions regarding instrument
operation or documentation to CANNON Instrument Company.
•Do not deviate from the installation, operation, or maintenance procedures described in this
manual. Improper use of the CAV 4.1 may result in a hazardous situation and/or void the
manufacturer’s warranty.
•Handle and transport the unit with care. Sudden jolts or impacts may cause damage to
components.
•Observe all warning labels. Never remove warning labels.
•Never operate damaged or leaking equipment.
•Unless procedures specify otherwise, always turn off the unit and disconnect the MAINS cable
from the power source before performing service or maintenance procedures, or before moving
the unit.
•Refer all service and repairs to qualified personnel.
Navigating the Manual
Since the CAV 4.1 uses both a touchscreen interface on the instrument and the VISCPRO II computer
software application, the instructions are broken into sections for each type of controlling software. The
header of each section notes CAV 4.1 GUI Touchscreen or VISCPRO II so the operator knows whether
the procedures apply to the touchscreen instrument software, or the computer-controlled VISCPRO
software.
CAV 4.1 GUI Touchscreen refers to the instrument touchscreen.
VISCPRO II refers to the computer software.

Connect Hoses
Assemble the CAV 4.1 on a secure surface with sufficient room behind the instrument to maintain a
clear airflow and allow for unimpeded connection of the solvent inlet and waste outlet tubing.
Figure 2 — Tubing Connections (Rear Close Up)
1. Place the CAV 4.1 on a solid, level workbench located near a MAINS AC power connection capable of
providing sufficient current (10 A at 115 VAC) to the CAV 4.1. Depending on the materials tested,
solvent used, and laboratory regulations, the work area may also need to be equipped with a
ventilation system.
2. Place the waste receiver beneath the CAV 4.1. In order to promote proper gravity drainage, the top
of the waste receiver must be lower than the waste outlets on the back of the instrument.
3. Place the solvent bottles alongside or beneath the CAV 4.1.
4. Measure and cut the 1
∕
8
" blue FEP tubing to use as the solvent tubing. Each piece of tubing must run
from the solvent inlet well to the bottom of a solvent bottle.
5. Connect the solvent tubing to the CAV 4.1:
a. Remove the cover plate from the solvent inlet well.
b. Thread the tubing through the solvent inlets on the back of the lid.
c. Unscrew the appropriate compression connector and slide it onto the tubing.
d. Slide the tubing onto the flared inlet pipe and hand tighten the compression connector.
6. Insert the solvent tubing into the solvent bottle:
a. Thread the tubing through the bottle cap.
b. Screw a 20 micron filter onto the end of the tubing.

combining both waste tubes into one tube before entering the waste
receiver. A brass elbow is also provided to connect the waste tubing to
the waste receiver.
8. Measure and cut the 1 ∕

Caution: Do not overtighten the waste outlet compression nut.
9. Connect the bath waste tubing to the CAV 4.1:
a. Fully insert tubing into push to lock fitting.

11. Measure, cut, and install the 6 mm blue FEP tubing as exhaust tubing.
Fill the Bath
The temperature bath must be filled with the appropriate silicone fluid prior to operation. The viscosity
of the fluid depends upon the temperature of the bath during most operations. Refer to Table 6 for
proper bath fluid selection.

Procedure
1. Turn off power to the CAV 4.1 instrument and let the bath cool to room temperature.
2. Lift the hood to access the top of the bath.
3. Remove the float from the top of the bath and set aside. This provides the opening to fill the bath.
Refer to Figure 5.
Figure 5 — Remove Float from Top of Bath to Reveal Opening
4. Insert funnel into the hole now available by the removed Float. Refer to Figure 6.

5. Using the funnel, fill bath with the appropriate silicone bath fluid to the applicable fill line on the
bath. The top line is for lower temperatures (100 °C) and the bottom line is for higher temperatures
(135 °C and above). Refer to Figure 7 and Figure 8.

6. Remove funnel and replace float into top of bath. The CAV 4.1 bath is now filled.
Drain the Bath
It may be necessary to periodically drain the bath. Follow the instructions in this section and use caution
to avoid exposure to hot bath fluid.
1. Turn off power to the CAV 4.1 instrument and allow bath to cool to room temperature.
Warning: When working with the bath in any capacity, and especially when
emptying the fluid, make sure the bath is completely cooled
(ambient temperature) prior to working or emptying bath fluid.
2. Lift the CAV 4.1 hood to access the bath. It flips up, as shown in Figure 9.
Figure 9 — Lift the CAV 4.1 Hood

3. Remove the front panel of the CAV 4.1 by gently pulling it away from the front of the instrument, as
shown in Figure 10. Set the front panel aside.
Figure 10 — Remove Front Panel and Set Aside
4. Insert one end of the yellow tubing onto bath drain, leaving at least ¼" above the hose on the
nozzle. The hose must cover the large end of the nozzle, without making contact with the bath itself.
There must be adequate room above the hose to access the nozzle with the ¼"open end wrench
that opens the drain. Do not let the hose cover the entire drainage tube. Refer to Figure 11.
