Page 8: Working Principle
6. Working Principle This instrument is a rotary viscometer. Therefore a rotor/spindle can be rotated constantly by the variable speed stepping motor installed in the machine. Rotating the standard spindle, the spindles will be subject to a torque percentage proportional to liquid viscosity because of the liquid viscose hysteresis. - Page 9 Step 7: Press the ‘RUN’ button to start the measurement cycle. Wait for at least 5 complete rotations to get a stable reading. The value displayed against mPa.S is your viscosity. Scenario B: Spindle Number & Rotor is not know, but approximate idea of viscosity is know Step 1: Use the below table to guess the the spindle number &...
- Page 10 Step 7: Press the ‘REVS’ button to input the speed you wish to measure at. Use the arrow keys to toggle between 8 speeds from 0.3 RPM to 60 RPM. Then press ‘ENT’ to save your speed selection. Step 8: Press the ‘RUN’ button to start the measurement cycle. Wait for at least 5 complete rotations to get a stable reading.

In case the spindle and speed is wrong, the machine will give a message such as ‘Finished. Try Spindle S3’. If so, repeat the Step 6 until the desired spindle & speed is known. Step 7: Once done, the machine shall give a decision if this spindle is correct or you need to experiment with another spindle. - Page 12 4. The instrument mounted with rotor should not be revolved without liquid to avoid damaged to the axis tip. 5. Extreme care should be taken for mounting or removing rotors. Slightly lift the connecting screw bolt to avoid a transverse force acting on the rotor sensors.
