CHAPTER

1 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.

Manual

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

VISCPRO® software installation and operation

 

CAV 2000 Series equipment and operation

 

 

Calibration, service and maintenance procedures

 

For additional information on initial installation and instrument setup,

 

refer to the Installation & Setup Guide.

 

Applications

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

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 Classifica-

 

 

tion 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

An accepted unit of kinematic viscosity is one centimeter squared per

 

second, which is called one stoke. The centistoke (which is equivalent to

 

1 mm2/s) is the unit of measure most frequently used.

Methodology

ASTM Methods D 445 and D 446, included with this manual, describe

 

appropriate test methodologies and instruments for glass capillary

 

viscometry.

Manual viscometers

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).

Automatic viscometers

For automatic viscometers, ASTM D 445 Section 6.1.2 states, “Auto-

 

mated apparatus may be used as long as they mimic the physical condi-

 

tions, 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 require-

 

ments are met.

CAV tube characteristics

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).

NOTE

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.

Safety cautions

 

 

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.

WARNING

3

Make sure that you read and understand all operating instructions and safety precautions listed in this manual before installing or operating your unit. If you have questions regarding instrument operation or documentation, contact CANNON® Instrument Company. Do not deviate from the installation, operation or maintenance procedures described in this manual. Improper use of the CAV instrument may result in a hazardous situation and may 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.

Never operate the unit without appropriate levels of approved bath fluid in the bath.

(CAV-2200 only) Do not fill the expansion vessel higher than the cold fill level.

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. Always empty the bath and disconnect cable and tubing connections to the Service Unit and Solvent Dispensing System before moving the unit.

Never operate the equipment with damaged mains power cables. Refer all service and repairs to qualified personnel.

In addition to the cautionary statements listed previously, additional cautions may be posted throughout this manual. These cautions, identified by the caution symbol (see left) indicate important operational procedures. 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 unit.

Hot surface cautions may be attached on or near hot surfaces of the CAV. Avoid touching hot surfaces, particularly when operating the CAV at bath temperatures exceeding 50°C.

The Protective Conductor Terminal symbol is used to indicate required ground connections for your instrument electrical supply.

When supplying power to this instrument, ensure that the protective ground (earth) terminals of the instrument are connected to the protective conductor of the (supplied) line (MAINS) power cord. Use only the manufacturer-supplied power cord, which should be inserted in a socket outlet (receptacle) which is also provided with a protective ground (earth) contact. Do not use an extension cord (power cable) without a protective conductor (grounding).

CHAPTER

2 TESTING SAMPLES WITH THE CANNON AUTOMATIC VISCOMETER

This chapter of the manual will provide information on testing samples using the CAV-2100 or CAV-2200 instruments. Observe the safety cautions noted in the introductory chapter when operating equipment. The CAV should only be operated by qualified personnel.

Preparing the CAV

Turning on the CAV

1. If CAV power is off, turn on the CAV Bath Unit by rotating the red

 

power switch on the control panel clockwise. Provide power to the

 

CSU Service Unit (rear panel On/Off switch) and the Solvent Dis-

 

pensing Unit (front panel On/Off switch).

NOTE

If it is necessary to

 

cut power to the CAV

 

Bath Unit, press the

 

power switch IN.

Preparing sample trays

Sample trays will slide into place along the grooved track in the sample table. Plated steel vial adaptors should be placed in the circular recesses in the tray.

Glass sample vials slide into the adaptors. To position the first sample vial under the viscometer tube in preparation for testing, slide the tray forward until the detente mechanism engages. 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”). During sample testing, trays are automatically advanced by the pneumatic system.

Electrical connections

For heated sample trays, verify that the attached three-pin tray cable is

 

connected to the interior wall connector above the sample table.

Using a temperature probe A recessed thermometer well at the front of the sample tray permits insertion of a temperature probe to monitor tray temperature.

Tray/drain heat operations To provide power to the heated sample trays and/or heated drain lines which may be installed on your CAV unit, use the heater ON/OFF switches on the left side of the front panel. These two switches provide power to leftand right-hand heating elements. To adjust temperature, use the Adjust knobs on the upper front panel of the Bath Unit. Turn the knobs clockwise to increase temperature and counterclockwise to lower it. The knobs regulate the duty cycle of the heaters for the sample trays and the drain lines. The low-temperature sample heaters will maintain temperature stability as high as 80°C. The high-temperature sample heaters will maintain temperature stability as high as 100°C.

CAUTION Avoid skin contact with heated sample trays, as burns may result. Use appropriate protection when handling heated samples, vial adaptors, and sample trays.

Removing the thermometer

ASTM thermometers with speciallyfitting adaptors for the CAV instrument (see photos) are available from CANNON® Instrument Company. Digital therometers meeting the ASTM D 445 specifcation are also available.

1.To install the reference thermometer, check the current temperature of the CAV bath and select the calibrated thermometer appropriate for that temperature.

2.Using the two opposing 0.05” Allen screws, secure the thermometer

adaptor plate to the connector on the thermometer cable.

3.Using a ladder to access the top of the CAV Bath Unit, remove the knurled cap, ferrule and O-ring from the thermometer holder.

4.Insert the thermometer assembly into the holder until the plug with O-ring is seated inside the top of the holder. Rotate the plug until the thermometer scale is easily visible from the Bath Unit front window.

5.Slide the ferrule over the end of the plug until it seats against the O- ring.

6.Place the knurled cap over the plug and rotate the cap clockwise to secure the cap to the top of the thermometer holder. Tighten finger tight to seal the connection.

To remove the reference thermometer, permit the bath to cool below 80°C and reverse the above procedure. Use appropriate safety procedures when handling the thermometer assembly, as it contains mercury.

Local mode operation

 

The Local mode option permits manual control of CAV functions via the

 

control keypad on upper front panel of the Bath Unit. Local mode offers

 

the advantage of convenient and quick testing for an individual sample.

 

The single-sample drop time or kinematic viscosity is displayed on the

 

vacuum fluorescent display (VFD).

NOTE

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.

Selecting Local mode

To 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 opera-

 

tion, then the instrument is in Local mode.

NOTES

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.

Setting temperature

WARNING

NOTE

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.

To 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.

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

18

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 viscos-

 

ity (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).

Aborting a test

To immediately halt testing for a given tube/tray (left/right), press the

 

 

Stop Left and/or Stop Right button on the keypad. On rare occasions

 

when it is necessary to quickly abort tests on both tubes and remove

 

power from the unit, press the red power button on the control panel.

NOTE

Aborting a test using either method clears all sample test information for

 

that tray. If test actions are aborted, it is the responsibility of the user to

 

restore the instrument to a safe state before running tests (see Local

 

mode diagnostics/maintenance in chapter 5 for more information).

Concluding a test

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.

NOTES

Any incomplete keypad command sequence may be cancelled by

 

pressing the keypad button that initiated the sequence.

Acceptable keypad input is indicated audibly with a short beep. Unacceptable keypad input is indicated audibly with a longer tone.

Remote operation (computer-controlled)

Local/Remote operation of the CAV is selected via the RMT/LOC button on the control panel. Pressing the button will toggle between the Remote and Local operation modes. The Remote mode option permits automatic control of CAV functions via the VISCPRO® controlling software.

Remote mode offers the advantage of multi-drop, multi-sample automatic testing for up to 100 samples depending on tray type. Sample data is automatically stored to the VISCPRO® database for future reporting/data collection. Additionally, several reports (analyses) may be used to calculate and display kinematic viscosity and viscosity index (VI) values. See the chapters on VISCPRO® analyses for further information.

All analyses provide a dynamic operation mode which can immediately display and transmit test results to your computer screen, printer, and/or serial port for in-house data collection. See Chapter 6 for more information on configuring analyses.

To select Remote mode operation, press the Remote/Local (RMT/LOC) button on the keypad on the Bath Unit until the front panel vacuum fluorescent display indicates REMOTE operation. If the display does not indicate REMOTE operation, then the instrument is in Local mode.

NOTE

Remote mode may only be selected when the CAV is idle.

Setting temperature

To set the temperature in Remote mode, load the VISCPRO® software and click Configuration. Select the CAV from the list of available instruments and click Tray Settings: Tube and Bath. Select the desired tube and type the desired temperature in the Bath Temp: field. Acceptable values are any numbers between 20°C and 100°C (150°C for CAV high-temperature models). If necessary, you may use the decimal point key to input temperature to the nearest 0.01°C. Press OK to save the temperature setting.

NOTE

To cancel temperature selection before completing the procedure, click

 

Cancel.

 

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 on the display for CAV-2100 models.

NOTE

Placing the instrument in Remote mode while the VISCPRO software is

 

loaded will reset the bath temperature(s) to match the VISCPRO set-

 

tings.

Testing samples

Loading software

1. Turn on the computer and load the CAV software by double-clicking

 

the VISCPRO® icon on the Desktop.

NOTES

If the software is already loaded, use your computer mouse to click Main

 

from the menu bar and click Poll for Instruments from the Main menu

 

options. This will establish communications between the computer and

 

the on-line instrument.

 

Permit the bath(s) to stabilize at test temperature before testing samples.

 

2. Pour sample material into the glass vial(s). Fill to within 1.3 cm (½”)

 

of the top of each vial (somewhat less sample may be required for

 

testing in lower bulbs of the viscometer). Insert the glass vials into

 

the steel carrier cylinders and place the cylinders into the sample tray.

NOTES

Do not fill the vials to the top. Sample overflow may damage the seals of

 

the LOAD cylinder. You should run calibration check standards per your

 

established laboratory procedures. Recalibrate the CAV (see Chapter 3,

 

Calibration) if result variance warrants.

3.Place the sample tray into the track underneath the viscometer tube. Push the sample tray forward until the first vial is under the viscometer tube. 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”).

4.Ensure that the splash guard(s) in front of the viscometer tube has been secured in place with the thumbscrew. If a splash guard has been removed, replace it.

!CAUTION The splash guard(s) may be removed to allow the user to handle the

sample not yet running (replace with a different sample, etc.). However, make certain to return the splash guard to its proper position to prevent sample/solvent contamination and to protect the viscometer tube tip. Do not allow your hands to contact or obstruct the pneumatic mechanism or heated sample trays and electrical connections.

5.Check the thermometer in the temperature bath to make sure the bath is holding the proper temperature. If necessary, calibrate the CAV temperature control probe using the temperature calibration procedure in Chapter 3.

6.Open the View Instrument Group window (if it is not already open) by clicking View Instrument from the Main menu and selecting the desired instrument group from the list box (see Chapter 4 for more information).

NOTE

Once sample information is entered, the software automatically assigns

 

a sample action, Measure Sample Viscosity, for the sample. If you do not

 

enter a sample ID, the sample is automatically labeled Unknown.

 

To select or change a sample action, highlight the appropriate Sample

 

ID(s) using the mouse or arrow keys, then click the RIGHT mouse

 

button to access sample action options:

 

Then you may select the desired action by highlighting it and click-

 

ing the left mouse button.

NOTE

For additional information on software data entry features, including

 

multiple sample selection and cut & paste options, see Testing

 

samples—software options in Chapter 4.

Running check standards

If Verify Known KV is selected as the test option for a sample, the

 

Viscosity Action window will open automatically. Enter the neces-

 

sary check standard data, including the Check Standard viscosity

 

from the standard bottle, and click OK to complete data entry. To

 

revise or confirm standard data, right-click on the desired sample ID

 

from the list box and select Configure from the popup menu choices.

NOTE

See Chapter 4 for additional information on the Viscosity Action window.

 

10. Continue entering sample information for all desired trays. When

 

sample ID data entry is complete, check the Tray Status window to

 

verify that all trays are ready for testing.

 

11. Click on the RUN button at the bottom of the Sample Input win-

 

dow. The Select Trays window will open.

 

12. Click on the check box(es) to select the desired prepared tray(s) for

 

automatic testing. Then click OK to begin the CAV test(s).

Pausing a test

To temporarily halt testing for a given tube/sample, click the Pause

 

 

button from the Sample Input window. Then select the desired tray(s)

 

and pause action(s) from the Select Trays window (Pause Now will

 

immediately pause test actions; Pause after current sample will pause

 

testing after the current test is complete). Click OK to pause testing for

 

the selected tray(s).

NOTE

If the test was paused prior to the initiation of the Wash cycle, drop time

 

data for that sample will be discarded.
