INTRODUCTION/SOFTWARE
INSTALLATION
The CANNON® Automatic Viscometer (CAV 2000 Series)
The CANNON® Automatic Viscometer (CAV) is a completely automatic viscometer designed for unattended operation. The operator places samples in small vials in the sample holders, enters sample identification information and initiates the testing with software or front panel keypad commands. Without any further operator involvement, the CAV deter­mines kinematic viscosity , cleans the capillary tube(s) and prepares the instrument for the next test. All pertinent test data can be saved to a computer database for future retrieval and reporting.

This manual is designed to provide the operator with information about:

CAV 2000 Series equipment and operationCalibration, service and maintenance procedures
For additional information on initial installation and instrument setup, refer to the Installation & Setup Guide.
Previous CAV models have been used in laboratories worldwide for over two decades. CAV instruments can be found in R&D laboratories, refinery quality control laboratories, blending plants, and independent testing laboratories. The CAV is ideally suited for the analysis of both transparent and opaque samples. A variety of materials, such as used oils, marine fuels, residual fuels, and crude oils can be tested with ease.
Precision for the kinematic viscosity determination of the CAV equals or exceeds that specified in ASTM Method D 445. This method is required by the Society of Automotive Engineers (SAE) Engine Oil Viscosity Classifica­tion SAE J300.

Measuring kinematic viscosity
Kinematic viscosity is a measure of the internal resistance to flow of a fluid under gravity with the pressure head being proportional to the density of the fluid. For any particular viscometer, the time of flow of a fixed volume of fluid is directly proportional to its kinematic viscosity .
Units of measure
Methodology
Manual viscometers
Automatic viscometers
An accepted unit of kinematic viscosity is one centimeter squared per second, which is called one stoke. The centistoke (which is equivalent to
2
1 mm
/s) is the unit of measure most frequently used.
ASTM Methods D 445 and D 446, included with this manual, describe appropriate test methodologies and instruments for glass capillary viscometry.
Sections 9-11 of ASTM D 445 provide detailed instructions for using manual viscometers. ASTM D 446 suggests a minimum flow time of 200 seconds for nearly all the glass capillary viscometers (see tables in ASTM D 446).
For automatic viscometers, ASTM D 445 Section 6.1.2 states, “Auto­mated apparatus may be used as long as they mimic the physical condi­tions, operations or processes of the manual apparatus they replace ... The automated apparatus shall be capable of determining kinematic viscosity of a certified viscosity reference standard within the limits stated ...”
Thus, automated viscometers can be used with flow times less than 200 seconds, as long as the kinetic energy correction and precision require­ments are met.
CAV tube characteristics
NOTE
Safety cautions
CANNON
®
Automatic Viscometer Models CAV-2100 and CAV-2200 with VISCPRO® Instruction & Operation Manual
Each standard viscometer tube has three bulbs, each of which has its own calibration. The normal flow times for each bulb are 60-400 seconds. Each tube has a hundredfold measurement range (for example, range from 2-200 cSt or 20-2000 cSt for each tube).
CANNON® Instrument Company has not recommended the use of longer flow times with the CAV, as shorter flow times allow greater productivity. With longer flow times, the data throughput would be significantly reduced. However, the viscometer and software design does permit longer efflux times (up to 600 seconds) as desired by the user.
Please observe the following safety procedures and notices for proper operation of the CAV:
Make sure that your unit is operated only by qualified personnel.
Version 2g — May, 2009; CANNON

NOTE
Selecting Local mode
NOTES
Setting temperature
WARNING
The VFD is equipped with a screen saver feature which will reduce the intensity of the display if the keyboard is not touched for five minutes. To restore the original intensity of the display, press any key on the keypad.
T o select Local mode operation, toggle the Remote/Local (RMT/LOC) button on the keypad on the Bath Unit to select Local mode operation. When the unit is in Remote mode, the front panel display will indicate REMOTE operation. If the display does not indicate REMOTE opera­tion, then the instrument is in Local mode.
Local mode may be selected at any time during CAV operation. Remote operations will be suspended. When switching from Remote to Local mode, it is the user’s responsibility to monitor the instrument tube state(s) and to properly prepare the instrument before running tests. Operator intervention is required to test each sample in Local mode. Additionally, test data is not saved to the VISCPRO® database and viscosity calculations must be performed manually.
Prior to setting the bath temperature, ensure that the reference thermom­eter in the bath is suitable for the desired temperature range. If not, remove thermometer from the bath (see previous page). If the bath temperature rises above the range of the thermometer, it may be dam­aged. Mercury thermometers pose particular problems, since mercury from a damaged thermometer may circulate with bath fluid.
CANNON
T o set the temperature in Local mode, press the Set Temp key on the front panel keypad, select the desired bath (CAV-2200 only) and input the target (desired) temperature(s) using the keypad characters. Then press the Enter key. Acceptable values are any numbers between 20°C and 100°C (150°C for high-temperature CAV models). If necessary, you may use the decimal point key to input temperature to the nearest 0.01°C.
NOTE
To cancel temperature selection before completing the procedure, press the Set Temp key a second time.
After the target temperature has been set, the CAV bath temperature will be adjusted to the target temperature and the bath will equilibrate at the test temperature. When the instrument has attained a temperature within

0.05°C of the target temperature, the current bath temperature will be displayed in large type (CAV-2100 only) on the display.
Preparing the bath
When operating in Local mode, visually check the condition of the viscometer tubes prior to initiating a sample run. If sample or solvent residue remains in the tube, use the Local mode options to wash and/or dry the tubes (see Chapter 5, Solvent wash by operator (Local mode)).
Testing samples
1. Pour the test sample into a glass vial and slide the vial into the steel
vial adaptor in the sample tray .
NOTE
Do not fill the vials to the top. Sample overflow may damage the seals of the LOAD cylinder.
2. Position the vial directly underneath the viscometer tube, using the
detente mechanism as a guide in orienting the sample. A heated sample tray should snap into position against the detent mechanism when the front of the tray extends approximately 2 centimeters (3/4”) over the edge of the sample table. The forward edge of an unheated tray will be indented approximately 2.2 centimeters (7/8”).
3. Press the Test button.
4. Select the desired tube for testing (Left (1) or Right (2)).
5. Select the desired protocol for the sample drop:
Run (Determine Bulb) will calculate the optimal test bulb. Run (Use Previous Bulb) will test the sample using the same bulb
as the previous test (this option is desirable when averaging multiple drop times for the same sample).
The sample will be tested and the drop time and/or kinematic viscos­ity (see next page) will be indicated on the VFD.
6. After the test has been completed, you may rerun the sample using
the above procedure, or wash the tube using the keypad WASH option (see pages 18-19 for details on keypad options).

Concluding a test
19
At the conclusion of a test, the drop time for the sample will be displayed on the display screen. Record the drop time and press the Enter key to return to the temperature display . Then remove the sample from the tray.
CAUTION
Use appropriate procedures when handling heated sample trays and heated samples to avoid the possibility of burns.
Empty the oil from the sample vials into the appropriate container(s) for use/disposal and clean glass vials per approved laboratory procedures.
Wipe any excess oil from the table, sample tray and vial holders (glass vials only) using an absorbent paper towel. If necessary , clean these items by wiping with a paper towel wetted with appropriate solvent.
Obtaining kinematic viscosity (KV) readings in Local mode
Local/Remote operation of the CAV is selected via the RMT/LOC button on the CAV keypad. Local mode operation involves CAV control via the keypad. Remote operation involves CAV control via the VISCPRO software interface. Pressing the RMT/LOC button on the CAV keypad will toggle between the Remote and Local operation modes. To obtain kinematic viscosity readings in local mode with the CAV 2000 Series instrument, calibrate each bulb for each bath at the desired bath tempera­ture using VISCPRO II with the instrument set in REMOTE mode.
After calibration, open the Tray Settings: Tube and Bath window for the desired instrument. Make sure the settings are correct and close the window by clicking the OK button. This action will transmit the bath temperature(s), the soak times, and the current bulb calibration constants to the instrument.
Press the RMT/LOC button on the CAV keypad to change the instrument mode to LOCAL. Then press the Menu button on the CAV instrument. On the screen, select option #7: Display KV : YES/NO. Toggle the #7 button to select the desired option. If YES is selected, the KV will be displayed at the end of a test.
NOTE
If the instrument is set to display KV, it will only display KV if the tube calibration constants have been loaded as described above; otherwise, it will display the efflux time. If multiple drops are required for a result, the customer will need to average the KVs resulting from each drop.
Other Local mode keypad options
The Local mode keypad options described above are the more common functions available. The Keypad Options table (see next pages) contains a list of all Local mode keypad options, including entry parameters and (where applicable) default instrument settings.
Any incomplete keypad command sequence may be cancelled by pressing the keypad button that initiated the sequence.
