    connection! Verify that the voltage and the frequency match with the specifications for the viscometer. Before turning on the machine, let it sit for some time so that it acclimates to the surrounding temperature in order to avoid a short-circuit caused by condensation. The fluctuations of the power source should not surpass ±10 % of the nominal voltage 3.

    (directive 89/655/CEE). Fungilab recommends using the carry-case provided with the equipment for making any kind of delivery. Please, keep the carry-case in a safe location. In case of transporting the equipment or during long storage periods, always use the carry-case by placing each part as shown in the picture.

  • Page 14: Important Rheological Information

    10. Important rheological information To obtain precise results it is necessary to know the most important rheological properties of the sample. Newtonian fluids The viscosity of these fluids does not depend on the shear rate meaning that at any speed the viscosity is the same.
  • Page 15 NOTE: The turbulent behaviour of a fluid can produce falsely high results in viscosity tests. Normally, turbulent behaviour is due to an excessively high rotation speed in relation to the viscosity of the sample (see detailed Warning further on). FACTORS AFFECTING VISCOSITY There are many variables that affect the rheological properties of products, so it is very important to take the following factors into account.
  • Page 16 Examine each spindle before using it. If it’s damaged or eroded in such a way that its dimensions are changed, it will provide false results for your viscosity reading. The spindle protector (provided with every Fungilab rotational viscometer) protects the spindle and the viscometer axle and it is important for the reading of low viscosities with standard spindles.
  • Page 17 The viscosity reading must be executed under laminar flow condition, not turbulent flow conditions. The first consideration is linked to the precision of the instruments. All of the FUNGILAB rotational viscometers guarantee a precision of () 1% from the bottom of any spindle/rotational speed combination scale.
  • Page 18 Turbulent flow: “non-linear” flow lines. Impossible to predict the exact movement of the fluid. Very quick. For rotational systems, this means that the fluid’s movement must be circumferential. When the internal forces of a fluid end up being too great, the fluid can become a turbulent flow, in that the particles that make it up become unpredictable, making it impossible to analyse it with standard mathematical models.

    The piece named G has two possible holes for the upper screw. The top hole is a Universal hole to screw our low viscosity adapter to other brand viscometers. The bottom hole is to screw to Fungilab pieces. NOTE: Before starting with the measurements, make sure the viscometer is correctly balanced (check it with the bubble level).
