INTRODUCTION/INSTALLATION
The miniAV®-X Automatic Viscometer
The miniAV®-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 miniAV-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
miniAV-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 miniAV 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
miniAV-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, included with this manual, 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.
miniAV-X tube characteristics
NOTE
Safety cautions
CANNON
®
miniAV-X Automatic Viscometer with VISCPRO® Instruction & Operation Manual
Version 1.Ob— March, 2012; CANNON
Each standard miniAV-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 miniAV-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 miniAV-X:
Do NOT lift the unit by the side panel “ears”. Always support the
unit from the base when moving or lifting.

Calibrating the miniAV-X
Notes on computer-directed miniAV-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
miniAV-X temperature probe and viscometer tube.
A computer is required for miniAV-X operation. The computer provides
for automatic control of miniAV-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 miniAV-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.
