For the installation of Fungilab viscometer, please pay more attention to the following questions. For specific questions about installation and use, please call our engineers.

1) Care should be taken when loading and unloading the rotor. When loading and unloading, the connecting screw should be lifted slightly for operation. Do not use too much force or force the rotor laterally to avoid bending the rotor.

2) Please do not put the viscometer installed with the rotor on its side or upside down.

3) Keep the end face and thread of the connecting screw and rotor clean, otherwise it will affect the degree of shaking of the rotor.

4) Hold the viscometer with your hands when lifting it up and down to prevent the viscometer from falling due to its own weight.

5) After replacing the rotor, please input the new rotor number in time. After each use, the replaced rotor should be cleaned (wipe clean) in time and put back into the rotor rack. Please do not leave the rotor on the instrument for cleaning.

6) When changing the liquid to be measured, please clean (wipe clean) the rotor and the rotor protection frame in time to avoid measurement errors caused by the confusion of the liquid to be measured.

7) The instrument and the rotor are one-to-one matching, please do not confuse several instruments and rotors.

8) Please do not disassemble and adjust the instrument parts at will.

9) When moving and transporting the instrument, install the yellow cap on the connecting screw, tighten the screw, and put it in the packing box.

10) After installing the rotor, please do not rotate it for a long time without liquid, so as not to damage the shaft tip.

11) Many of the suspensions, emulsions, polymers and other high-viscosity liquids are "non-Newtonian liquids", and their viscosity values ​​change with changes in conditions such as shear speed and time. Inconsistency with the results measured under the time is normal and not an instrument error. For the determination of non-Newtonian liquids, the rotor, rotational speed and time should generally be specified.

12) Doing the following points will help to measure more accurate values:

Accurately control the temperature of the measured liquid.

Immerse the rotor in the liquid to be measured for a long enough time to make the temperature of the two consistent.

Maintain the homogeneity of the liquid.

When measuring, place the rotor in the center of the container, and be sure to install the rotor protection frame.

Ensure the cleanliness and shaking of the rotor.

When the high speed measurement immediately changes to low speed, the machine should be turned off, or the measurement time at low speed should be a little longer, so as to overcome the error caused by the rotational inertia of the liquid.

Use No. 1 rotor when measuring low viscosity, and No. 4 rotor when measuring high viscosity.

When the viscosity is measured at low speed, the measurement time is relatively longer.

During the measurement process, due to the need to change the rotor, the liquid to be measured, etc., after changing the position of the viscometer by rotating the lifting chuck, the horizontal position of the viscometer should be checked and adjusted in time.
