First, insert the lifting column into the hole provided in the base and secure it with a nut. Note: The lifting button is on the right side. Hold the fgxing screw while simultaneously screwing in the lifting guide. Next, remove the screws from the main unit connecting rod and insert it with the holes facing down into the mounting hole on the bottom of the main unit. Connect the main unit connecting rod to the main unit base plate using the hexagonal screw that was removed earlier and tighten it. Then insert the main unit with the connecting rod into the mounting hole of the lifting column, and tighten the fgxed knob after straightening it. Adjust the three leveling feet located under the base so that the level bubble on the front of the device is in the center of the black circle. Remove the protective cover located under the lid of the device, connect the device to the mains and turn on the viscometer. Check that it is correctly assembled as shown in fggure 2. Figure 3 shows the spindles L1 ... L4 and the spindle protection frame supplied with the machine.

Its structure is shown in fggure 4. This component can only be used when measuring spindle L0 and is not suitable for other spindle tests. Installation of the L0 spindle is carried out as shown in fggure 5. First, turn the L0 spindle clockwise on the spindle connection screw (universal joint). Insert the fgxing sleeve from below into the cylinder of the lower unit cover. Be careful not to touch the L0 spindle, and tighten it with the sleeve fgxing screw. Pour 22 ml of sample into the test vessel. Slowly insert the sample tube into the spindle and secure it with the clamp and the fgxing screw. All the installed parts of the L0 spindle are shown in fggure 6. Check the temperature of the liquid and adjust the height. Note: When using the L0 spindle, make sure there is always liquid in the sample tube. On the other hand, when using the L0 spindle, remove the protective frame for the spindles (see fggure 3) and place the mounting bracket for the L0 spindle in its place. Note that when using the L0 spindle, no-load rotation is not allowed when it is not fglled with fhuid. When using the L0 spindle, it is not necessary to install a spindle protection frame.

The viscometer has a power failure memory function, i.e. the spindle number, revolutions and timed length established before a power failure will be retained and displayed after restart, so that the user can easily use them. 6.2 Procedure Figure 10 Press the "S/V" key, select the spindle number and the appropriate speed, and press the "RUN" key to start the test. The test screen is shown in fggure 10. » S L2# » V 60.0 RPM » 300.00 cP » 60.0% » 25.5 ºC » 05:00 Number of the spindle selected for the test. Speed selected for the test. Viscosity value obtained in the test. Torque value in % at current rotor speed. Temperature value obtained in the temperature sensor test. Actual start of the viscosity test which lasts 5 minutes (this time is only shown once the viscometer has started the test). After starting the measurement, it is necessary to wait until the instrument has rotated between 4 and 6 times. After rotating the instrument between 4 and 6 revolutions, fgrst look at the "%" value on the bottom line. This value should only be between 10 and 90%. It is only valid if it is within these percentages, and its viscosity value can be read at that moment. If the percentage value "%" is less than 10% or greater than 90%, it means that the current range selection is incorrect and another measuring range must be selected. The specifgc method of operation is as follows: if the value of the "%" is less than 10% because the range selection is too large, you must reduce the range, you can increase the speed or replace the rotor with a larger one; if the value of the "%" is greater than 90%, you must increase the range, you can reduce the speed or replace the rotor with a smaller one. This instrument has an over-range alarm function. When the torque value is greater than 95%, the viscosity value is displayed as "EEEEEE" with an audible alarm. At this point, you should switch to a higher viscosity range for the test. To measure the viscosity of an unknown sample, the viscosity of the sample must fgrst be estimated before choosing the corresponding spindle and speed combination. If it is difficult to estimate the approximate viscosity of the sample, it should be assumed that the sample has a high viscosity before proceeding with the measurement with small to large spindles (cubing) and low to high speed. The principle of viscosity measurement is as follows: small spindle (cubing) and low rotational speed for a high viscosity fluid; large spindle (cubing) and high rotational speed for a low viscosity fluid. The measuring range for each spindle and speed combination is shown in the following table: RPM 6 rpm 12 rpm 30 rpm 60 rpm Spindle L0 100 50 20 10 Spindle L1 Spindle L2 Spindle L3 Full measuring range mPa·s 1000 5000 20 000 500 2500 10 000 200 1000 4000 100 500 2000 Spindle L4 100 000 50 000 20 000 10 000 7 PRECAUTIONS » As viscosity depends on temperature, the temperature value must be controlled to ±0.1°C when the instrument is operating at normal temperature, otherwise the measurement accuracy will be reduced. If necessary, a constant temperature tank can be used. » The surface of the spindle must always be clean. » The spiral has a linear part, so the percentage angle must be checked during measurement, and this value must be between 10 ... 90%. If the angle percentage is too high or too low, "EEEEE" will be displayed for torque and viscosity. In this case, the spindle or speed must be changed, otherwise the measurement accuracy will be reduced. » The spindles should be mounted or dismounted with care, gently lifting the universal joint. The spindle cannot be forced by horizontal tension or pulled downwards, otherwise the shaft will be damaged. » Given that the spindle and the universal joint are joined by a left-hand thread, the spindle must be mounted or dismounted in the correct direction of rotation (Figure 11), otherwise the universal joint will be damaged. Cylinder Universal joint Clockwise direction Spindle assembly Counterclockwise Dismantling the spindle Spindle Figure 11 » The universal joint must be kept clean. » The instrument must be lowered slowly, holding it with the hand to protect the shaft from vibrations. » The universal joint must be protected by the lid when the instrument is transported or handled. » Suspended liquids, liquid emulsions, high-content polymers and other high-viscosity liquids are, for the most part, "non-Newtonian". Their viscosity varies with shear rate and time, so the values measured will be different if measured with different rotors, rotation speeds and times (the result will also vary if a "non-Newtonian" liquid is measured with the same rotor at different rotation speeds). » For the installation of the temperature sensor, see the following fggure (this accessory is optional, it is not included in the delivery).
