Measurement

6.1

Turn on the viscometer

To turn on the viscometer, you have to press and hold the Enter button for 2 seconds.
First, the display shows an information screen where you can see the version of your viscometer and its
firmware, as well as the battery status.
After that, you are redirected to the main screen. Here you can see the rotational speed, the current
viscosity, the selected spindle, the battery status and the full scale percentage.
To turn off the device, press and hold the Enter button for a few seconds.
Note: The full scale percentage refers to the maximum viscosity reading, which can be achieved with the
attached spindle.
6.2

Select a spindle

If the selected spindle on the display does not match with the one you attached to the engine shaft, you
have to select a different spindle.
To do so, press the Up / Down buttons when you are in the main screen. Now you can navigate through
all spindles available. The display shows the name of the spindle on the left side and its measuring range
on the right side.
By pressing the Up or Down button you can go to the next or previous spindle. Once you have found the
attached spindle, press Enter to confirm the selection.

Take a measurement

First, please make sure that the viscometer is levelled properly. Next, use the height adjustment at the
side of the viscometer and adjust it so that the measuring vessel can be placed on the base plate without
touching the spindle. After you placed the vessel on the base, use the height adjustment again and set it
to the lowest position possible. The wheel of the spindle should now be inside of the measuring vessel
and covered with the fluid to be measured.
Now, turn on the viscometer, select the attached spindle and press the Enter button to start the
measurement.
You will see the following screen:
The question marks mean that the device is waiting for the viscosity reading. After a short time, the
reading will show on the display.
If the viscosity of the fluid exceeds the measuring range of the spindle or the device, the display shows
the following:
Note: The full scale percentage can show readings between 5 and 100 % of the full scale. The optimum
lies between 10 and 90 % f.s. When below 5 %, the display shows "0" viscosity.
When you have finished your measurement, press Enter to stop the measurement and the rotation.
