safety related instructions. Additionally local rules and regulations relating to environmental safety
and accident prevention should be observed.
1.2 User-responsibility
The user should
a) Only allow persons to work with the instrument who are familiar with the general instructions
on how to work safely and prevent accidents.
b) Regularly check the safety-awareness of personnel at work.
1.3 Responsibility of personnel
Before commencing work anyone appointed to work with the instrument should pay attention to
the general regulations relating to work safety and accident prevention. The safety chapter and the
warnings in this manual should have been read and understood.
1.4 Dangers
This instrument has been designed and constructed in accordance with state-of-the-art
technology and the acknowledged safety regulations. Nevertheless, working with the
instrument may cause danger to the life and health of the operator or to others, or damage to the
instrument or other property. Therefore the instrument should only be used for its
designated purpose, and in a perfect technical condition. Any defect that could have a negative
eect on safety should be attended to immediately.
1.5 Designated purpose
The Krebs viscometer is exclusively designed to be used to measure the viscosity of paint and

7 MENU EXPLANATION
This section describes in detail all the menu options the instrument oers.
7.1 General menu structure
Below is a high level overview of the Krebs viscometer menu structure.
The menu is navigated using
the buttons as indicated.

7.2 Main menu
7.3 Actual measurement
After switching on the unit, this is the main menu.
The machine will revert to the settings used the
previous time.
Place a can with the uid to be measured on the
base of the instrument making sure it is well
centered and magnetically secured.
Measure and record the uid temperature as
indicated by your local procedures.
Lower the instrument with the handle and with
that the spindle into the uid right up to the level
indicator on the spindle ’s shaft.
This is essential for a proper measurement.
With START highlighted (see section 7.2), pushing
the OK button will start the paddle motor and the
actual measurement.

In this example Manual measurement was selected
previously and it’s the operator that has to watch
the duration of the measurement and press the OK
button again to stop the spindle from turning.
(see section 7.5.1 for measurement type selection)
Follow your local instructions for the time to
measure.
In general it is wise to measure for a short time (e.g.
10 s) to prevent a change in temperature of the uid
being measured.
Note: Centipoise (cP) was selected as Unit and is
shown big. The other two units are also valid
measurements, but just shown smaller.
(see section 7.5.2 for unit selection)
After stopping, measure and record the uid
temperature as indicated by your local procedures.
Raise the instrument and its spindle and clean the
spindle with a cloth before removing the can.
Before taking another measurement or leaving the
instrument, it is advised to thoroughly clean the
spindle . See the Clean High - Low section to prevent
contamination.
Possible errors:
The uid being measured is too thick
(viscosity >5.000 cP)
The uid is too thin (<52 cP) or the spindle hasn’t be
lowered into the uid properly.

In the main menu, use the control buttons to
highlight CLEAN and press the OK button.
CLEAN is just the spindle turning in an appropriate
solvent, without measurements being made.
Next highlight Low speed or High speed and push
the OK button.
With a can, lled with appropriate solvent securely
installed (see also 7.3) and proper safety measures
taken against spillage or eye or hand contact, lower
the handle to start the cleaning process.
Raising the handle or pressing the OK button will
stop the spindle from turning.

7.5.1 Measurement type
In the main menu, use the control buttons to high-
light SETUP and press the OK button.
The Measurement type selection will allow the user
to select either Manual, Max hold or Timed measure-
ments as shown below.
Press the OK button
Manual measurement is started from the main
window and lasts as long as the operators decides.
Press the OK button to select and then navigate to
BACK and press the OK button to return to the main
window and start a manual measurement.
All three units (cP, KU and g) are shown with the
selected unit (see chapter 7.5.2) in a large font.

window.
Navigate to START and press the OK button to start a
Max hold measurement.
Here it shows cP but it could also have been KU or g,
depending on the unit selected in section 7.5.2.
Timed measurement lets the spindle rotate for the
set amount of time before taking and showing one
reading in a large font.
The time can be set by navigation to the digits
between [ ] and using the up and down buttons to
cycle from 1 to 9 and left and right to select a digit.
Pressing the OK button will stop the measurement

To perform a new measurement press the OK button.
The Sheen Krebs viscometer allows the user to set a custom value for the density. This density
setting inuences the calculated grams and Krebs using the actually measured centipoise (cP).

g is in grams, Ois viscosity in cP and Dthe density in g/ml
The Sheen Krebs viscometer allows for accurately setting the density of your product and
getting a more precise measurement of the viscosity in grams and in Krebs.
The grams and Krebs scale are hard linked to each other. This correlation is not the same as
commonly seen when calculating from cP to centistokes (cSt).
The value of 0,8760 as shown is the xed default and backwards compatible with previous
instruments and rmware releases and other commonly available Krebs viscometer brands.

7.5.3 Calibration
The required knowledge, experience and high quality and well calibrated tools are outside the scope
of a normal user instruction and it is therefore that the calibration of the Krebs unit is no longer part
of the manual.
A separate calibration manual will be made available on request.
Your Krebs viscometer can be recalibrated at the Industrial Physics factory and selected service
centers and distributors.
Using calibration oils with certicates, calibrated thermometers with 0,01 °C reading capability and 0,1
°C accuracy at 25 °C, in a well controlled environment, following ASTM D562 will allow a user to
check the instruments accuracy using the normal measurement functionality.
The Industrial Physics oils suitable for Krebs are: DV2205, DV2206, DV2207, DV2208, DV2209, DV2210.
