1 ABOUT YOUR VISCOMETER
The Elcometer Krebs Viscometer measures the viscosity of paints, varnishes, adhesives, pastes
and liquid inks in accordance with ASTM D 562 and other standards.
This simple-to-use instrument consists of a paddle mounted on the end of a rotating spindle. The
paddle is immersed in the sample and rotated at a constant speed of 200 revolutions per minute.
The viscometer automatically calculates the viscosity value from the power required to maintain the
speed of rotation of the spindle.
A digital display shows the viscosity of the sample in Krebs units, centipoise or grams.
The Elcometer Krebs Viscometer features manual or automatic operation. In automatic mode, at
the press of a button:
• the spindle lowers into the sample to a pre-set depth
• the instrument waits to allow turbulence in the sample to subside (the wait time is adjustable)
• the spindle rotates and the measurement is taken (the measurement rotation time is
adjustable)
• the spindle rises out of the sample.
The operation of the Elcometer Krebs Viscometer is based on the Stormer mechanical system. In
this system a blade rotates at a constant angular velocity and the variation of viscosity between
products is determined by modifying theweight (ingrams) neededto maintainthis constantvelocity.

Your Elcometer Krebs Viscometer is packed in a cardboard and foam package. Please ensure that
this packaging is disposed of in an environmentally sensitive manner. Consult your local
Environmental Authority for further guidance.
1.2 Standards
Your Viscometer can be used in accordance with the following National and International
Standards:
• AS/NZS 1580.214.1
• ASTM D 562
• ASTM D 1084-C
1.3 Krebs units
The Elcometer Krebs Viscometer is suitable for measuring in Krebs units (KU) the viscosity of
paints, varnishes, adhesives, pastes, liquid inks and other similar substances.
The Krebs unit scale is commonly used to refer to viscosity or consistency of paints that are applied
by brush or roller.
The Krebs unit is defined by following equation:
• For viscosity in the range from 200 cP to 2100 cP
KU = 1.1187 + 0.8542 ln ( 0.1938 v + 36 ) - 0.0443 [ ln ( 0.1938 v + 36 ) ] 2
• For viscosity in the range from 2100 cP to 5000 cP
KU = 1.8118 + 0.596 ln ( 0.1938 v + 36 ) - 0.0206 [ ln ( 0.1938 v + 36 ) ] 2
where:
• KU is viscosity in Krebs units
• v is viscosity in centipoise (cP)
Note: The equivalent viscosity in cP given by the instrument should only be used for comparison
between one sample and another; it must never be used for quantitative measurement of viscosity.
To maximise the benefits of your new Elcometer Krebs Viscometer please take some time to
read these Operating Instructions. Do not hesitate to contact Elcometer or your Elcometer
supplier if you have any questions.

4 THE SAMPLE
4.1 Sample quantity
To maximise the accuracy and consistency of test results, always use the same quantity of sample
for each test.
To determine the correct quantity of sample, do the following:
1. Place the sample container on the sample container support.
2. Attach the spindle to the drive head (see “Fitting the spindle” on page 8).
3. Switch on the instrument and select manual mode (see “Taking a measurement in manual
mode” on page 14).
4. Press [DOWN] until the spindle reaches the lowest position (the instrument will sound an
audible beep when the spindle reaches the lowest position).
5. Pour the sample into the container. Stop pouring when the surface of the sample reaches the
notch on the spindle shaft. If using the 600 ml glass beaker supplied with the instrument,
450 ml to 460 ml of sample will be required to reach this level.
6. Make a record of the quantity of sample used.
Whenever you conduct a test, always use this same quantity of sample. By doing this, you will be
able to perform different measurements with the same working conditions, therefore permitting
reliable comparisons between test results to be made.
4.2 Sample temperature
The temperature of the sample has a significant effect upon its viscosity. Always check the
temperature of the sample before conducting a test. The temperature of the sample must be stable
and at the value specified in the test standard.

8 TROUBLESHOOTING
8.1 Security stop
If an obstruction causes the up or down movement of the head to be impeded, or in the unlikely
event of a malfunction, an audible alarm sounds, the movement is stopped and the instrument
displays the following message:
1. Press [STOP] to switch off the alarm.
2. If appropriate, switch off the instrument, remove the obstruction and then restart the test.
3. If the malfunction persists, contact Elcometer or your local supplier.
8.2 Unstable readings
Unstable viscosity readings may be caused by changes in the temperature of the sample or by the
behaviour of the product itself.
Check that the instrument is level. If the readings obtained remain unstable, the temperature of the
sample should be controlled and stabilised. If the readings remain unstable the instability is due to
the interaction between the product sample and the movement of the spindle.
In this instance, the product is called ‘Non-Newtonian’ and the behaviour of the product can be
described as thixotropic, rheoplexic, dilatant, pseudoplastic, etc. The same settings (SWT, SMT
and temperature) should always be used to test this type of product.
8.3 Instrument does not zero
When the spindle is rotating in free air (not immersed in a sample), the viscosity reading should be
zero. If it is not zero, please contact Elcometer or your local Elcometer supplier.
9 CALIBRATION
Your Viscometer was calibrated at the factory before shipment and a calibration certificate was
included in the box. Additional calibration checks at regular intervals over the life of the Viscometer
are a requirement of quality management procedures, e.g. ISO 9000, and other similar standards.
Calibration checks may be carried out by the user of the Viscometer (see instructions below),
however if the calibration of the Viscometer is found to need adjustment, please contact Elcometer
or your local Elcometer supplier.

Checking Viscometer calibration
It is recommended that calibrated Krebs viscosity oil is used for checking calibration - see “Spare
parts and accessories” on page 17. Use calibration oil with a Krebs value close to that of the
samples you regularly test.
1. Pour the correct amount of calibration oil into the sample container.
2. Check the temperature of the calibration oil; it must be stable and at the value specified in the
test standard.
3. Conduct an automatic test of the calibration oil using the values for SWT and SMT specified in
the test standard.
4. Once the test has been completed, check the viscosity reading on the display. If the reading is
identical to the nominal viscosity of the Krebs calibration oil, your Viscometer is calibrated
correctly.
10 MAINTENANCE
The Elcometer Krebs Viscometer is designed to give many years reliable service under normal
operating and storage conditions.
10.1 Cleaning
Always clean the instrument and spindle after use.
Always remove the spindle from the instrument before cleaning. The spindle or motor
coupling will almost certainly be damaged if attempts are made to clean the spindle while it
is still attached to the instrument.
Do not use very aggressive solvents or wire brushes, metal scrapers, metal files or other metallic
tools. Do not use excessive force which might otherwise bend delicate spindles.
Clean the spindle and other parts using a suitable solvent only.
After cleaning and before storing the instrument ensure that all materials are removed and that the
instrument is dry.
10.2 Service
The Elcometer Krebs Viscometer does not contain any internal user-serviceable components. In
the unlikely event of a fault, the instrument should be returned to your local Elcometer supplier or
directly to Elcometer. The warranty will be invalidated if the instrument has been opened.
