INTRODUCTION/INSTALLATION
The miniQV-X Automatic Viscometer
The miniQV-X Automatic Viscometer is designed to automate the timeconsuming sample testing and cleaning operations required for determination of kinematic viscosity in accordance with ASTM D445 specifications. The operator places the test sample(s) in small vials in the sample
holder(s), enters sample identification information from the computer
keyboard, and initiates testing with software keypad commands. W ithout
any further operator involvement, the miniQV-X determines kinematic
viscosity and cleans the capillary tube(s) in preparation for the next test.
All pertinent test data can be saved to a computer database for future
retrieval and reporting.

Calibration, service and maintenance procedures
miniQV-X instruments are appropriate for many kinematic viscosity
measurement applications in R&D laboratories, refinery quality control
laboratories, blending plants, and
independent testing laboratories. The
miniQV-X 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 miniQV-X equals
or exceeds that specified in ASTM
Method D445. 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 D445 and D 446 describe appropriate test methodologies and instruments for glass capillary viscometry.
Sections 9-11 of ASTM D445 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 D445 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.

NOTE
Safety cautions
CANNON
®
miniQV-X Automatic Viscometer with VISCPRO® Instruction & Operation Manual
Version 1.0— October, 2008; CANNON
Each standard miniQV-X viscometer tube has two bulbs, each of which
has its own calibration. The normal flow times for each bulb are 40-400
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 miniQV-X, as shorter flow times allow greater productivity. With longer flow times, the sample 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 miniQV-X:
Do NOT lift the unit by the side panel “ears”. Always support the
unit from the base when moving or lifting.
®
Instrument Company

Make sure that your unit is operated only by qualified personnel.
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 miniQV-X
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.
Do not fill the bath 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.
Never operate the equipment with damaged mains power cables.
Refer all service and repairs to qualified personnel.

Do NOT insert a reference thermometer while the miniQV-X bath impeller is operating, as damage to the thermometer and/or viscometer tube
may result. Make certain to insert the appropriate reference thermometer
for the current bath temperature! Use appropriate safety procedures

WARNING
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. 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
thermo-meter may circulate with bath fluid.

Calibrating the miniQV-X
Notes on computer-directed miniQV-X operation
Reporting data
T o ensure accurate test results, your instrument may need to be calibrated. If necessary , follow the instructions in Chapter 3 to calibrate your
miniQV-X temperature probe and viscometer tube.
A computer is required for miniQV-X operation. The computer provides
for automatic control of miniQV-X functions using the VISCPRO
®
controlling software. Computer control permits data entry of up to ten
different sample IDs. Each of the identified samples can then be tested
with the miniQV-X instrument.
T est data for the samples is automatically saved 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 reporting option which can dynamically
display and transmit test results as testing is completed. Data can be sent
to your computer screen, printer, and/or serial port for in-house data
collection. See Chapter 6 for more information on configuring analyses.

TESTING SAMPLES WITH THE
miniQV-X AUTOMATIC VISCOMETER
This chapter of the manual will provide information on testing samples
using the miniQV-X. Observe the safety cautions noted in the introductory chapter when operating equipment. The miniQV-X should only be
operated by qualified personnel.
Turn on the miniQV-X Bath Unit using the power switch on the power
supply unit.
1. Turn on the computer and load the miniQV-X software by doubleclicking the VISCPRO® II icon on the Desktop.
NOTES
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 to stabilize at test temperature before testing samples.
2. Pour sample material into the glass
vial(s). For 20 mL vials, fill only half
full, as the viscometer tube will
displace sample in the vial. Approximately 10 mL of sample should be
sufficient for testing in either bulb of
the viscometer.
Do not overfill the vials. Sample overflow
may create problems for the tube
cleaning cycle.
You should periodically test calibration
check standards per your established
laboratory procedures. Recalibrate the
miniQV-X (see Chapter 3, Calibration) if
result variance warrants.

3. Place the sample vials in the
carousel.

To permanently halt testing for a given tube/tray, click the Abort button
from the Sample Input window . Then select the desired trays from the
Select Trays window. Click OK to abort testing for the selected tray.
Aborting a test 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 Service menuoptions in chapter 4 for more information on tube washing and drying).
After automatic testing has been completed, make certain that:
