Page 9: Installing The Spindle Guard
OPERATING INSTRUCTIONS www.industrial-needs.com Care must be taken at this point, in order to avoid bending the spindle or damaging the shaft. Both the thread on the spindle and on the shaft must be absolutely clean and dirt free. The R7 spindle must be dipped into the liquid up to the middle marker point. The spindle is made of stainless steel. -
Page 10: Stand Construction (Optional)
OPERATING INSTRUCTIONS www.industrial-needs.com After assembling the spindle guard, it must be attached to the Viscometer. Carefully push the Viscometer shaft into the upper disc of the spindle guard assembly as shown in the diagram. Using the Allen key provided, carefully tighten the spindle assembly to the Viscometer shaft. Take extra care when tightening the fixing screws on the spindle guard to the Viscometer, so as to avoid damage to the shaft or spindle. - Page 11 OPERATING INSTRUCTIONS www.industrial-needs.com Carefully push the viscometer into the opening. When the shaft is in the holder, carefully press the viscometer downwards to lock it into the holder. Attach the viscometer with the included Allen screw to the holder.

Page 14: Measuring
OPERATING INSTRUCTIONS www.industrial-needs.com Measuring Start measurement Press the “ENTER” button to make the spindles rotate and to begin the measurements. The spindle starts to rotate; the display shows the following values: Speed (20, 30, 50 or 60 rpm), spindle selection as well as question marks which show that the viscometer is determining the viscosity values. - Page 15 OPERATING INSTRUCTIONS www.industrial-needs.com Finish Measurement To finish the measurement, press the “ENTER” button again. The current measuring value and the fraction of the full scale remain on the display. To start a new measurement, proceed as described above. Switch off Viscometer Press the “ENTER”...

OPERATING INSTRUCTIONS www.industrial-needs.com Do not forget to remove the spindles during the automatic “zeroing” It is also recommended that the “zeroing” is carried out on the stand and not whilst holding in the hand. If this is not possible, then the viscometers vertical alignment should be ensured. ... -
Page 18: About The Viscosity
The PCE RVI 3 is a portable rotational viscometer, used to measure the viscosity of many types of liquid. The measurements are taken in accordance with the Brookfield method. The readings obtained from the PCE-RVI 3 are perfect for comparing results taken using other types of Brookfield Viscometers. - Page 19 OPERATING INSTRUCTIONS www.industrial-needs.com The following variables can influence viscosity measurements: Viscometer type Dimensions of sample container Fill level Sample temperature Spindle Rotation speed Whether or not the spindle protector is being used. Duration of the test Invariably any change in working methods will lead to a change in results.
