    Brookfield Engineering or your local Brookfield dealer immediately. Any shipping damage must be reported to the carrier. Save the packing con- tainer, if possible, for future use when returning the viscometer to Brookfield or an authorized dealer for service.

  • Page 5: Installation

    This instrument is not intended for use in a potentially hazardous environment. In case of emergency, turn off the instrument and then disconnect the electrical cord from the wall outlet. Brookfield Engineering Labs., Inc. Page 5 Manual No. M02-312...

    (SI system). If the viscosity measurement is over range, “EEEE” will be displayed. Brookfield recommends a minimum reading of 10%. If the display value is between 0 and 10%, the unit display will flash to indicate an out of range condition. If the viscometer settles out with a final reading below zero, negative values will be displayed.

  • Page 7: Cleaning

    Note: When cleaning, take care not to apply excessive force which may bend the spindle shafft or otherwise damage the instrument. Brookfield Engineering Labs., Inc. Page 7 Manual No. M02-312...

  • Page 8: Getting Started

    Turn the power ON using the switch located on the rear of the base console. The display will sequentially show BROOKFIELD, then the model of the viscometer and the version number. After about four seconds, the main screen will be displayed (Figure II-1), indicating the temperature of the sample plate.
  • Page 9 Note: 1. CAP Viscometers allow for only one cone at a time of the same cone number to be calibrated to the viscometer. Multiple cones of the same cone number must each be calibrated to the viscometer before operation (refer to Appendix B). Brookfield Engineering Labs., Inc. Page 9 Manual No. M02-312...

    Brookfield recommends using the solvent trap at all times to enhance the temperature control of the sample material.

  • Page 11: Ii.5 Hold Time Settings

    Note: The TIMER (SEC) column will indicate the accumulated time of running at the moment the print key is pressed while the cone is rotating. This time value will not include the hold time. Brookfield Engineering Labs., Inc. Page 11 Manual No. M02-312...

    Pressing and holding the STOP/ESCAPE key during power up selects the viscosity display units and speed of rotation. Pressing and holding the STOP and PRINT keys simultaneously executes the printing of a new heading (Section II.7). Brookfield Engineering Labs., Inc. Page 12 Manual No. M02-312...
