  • Page 7: Introduction

    Introduction I. INTRODUCTION The CAP Series Viscometers are Cone and Plate geometry high shear rate instruments with integrated temperature control of the test sample material. The CAP 1000+ is a fixed shear rate viscometer rotating at 750 RPM and 900 RPM. The instruments operate by digital setting and display; rotational speed can be automatically timed to stop. High shear rate viscosity measurements are made over various viscosity ranges depending upon the cone spindle and the rotational speed (shear rate).

    Key Functions I.6 KEY FUNCTIONS Figure I-1 shows the control keys on the face of the viscometer display panel: NUMERIC 0-9 Used for data entry ENTER Accepts entered data STOP/ESCAPE Stops cone spindle rotation at any time / Exits data entry field DELETE Overwrites entered data PRINT Sends data to the parallel port Starts spindle rotation and measurement RUN TIME Selects time entry mode (time of spindle rotation)

  • Page 13: Viscosity And Temperature Display

    Viscosity is displayed in either P=Poise or cP=Centipoise (CGS system) or Pa•s=Pascal seconds or mPa•s=milliPascal seconds (SI system). If the viscosity measurement is over range, “EEEE” will be displayed. BYK-Gardner 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...

    II.1 POWER ON Turn the power ON using the switch located on the rear of the base console. The display will sequentially show BYK-GARDNER, 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 16: Ii.3 Speed Setting

    It is recommended to have the spindle in contact with the plate prior to introducing the sample material to ensure that the spindle is also at the temperature of test. BYK-Gardner recommends using the solvent trap at all times to enhance the temperature control of the sample material.

  • Page 17: Ii.5 Hold Time Settings

    Hold Time Settings / Run Time / Printing II.5 HOLD TIME SETTINGS Hold time sets the time period between when the RUN key is pressed and when the spindle begins to rotate. This time period is normally used to ensure thermal equilibrium of the sample and spindle.

    Run and Stop Keys II.8 RUN AND STOP KEYS The RUN key has three functions: 1. Press RUN to execute a timed measurement. 2. Press and hold the RUN key for continuous rotation when 00 is the timer setting. 3. Used in executing a cone calibration. The STOP key has three functions: 1.

    However, more weight means more wear on the cone and plate. Additional weights should only be considered when definitely required and removed when not required. Contact BYK-Gardner or your local BYK-Gardner Representative for details on the above information. III.3 MAKING VISCOSITY MEASUREMENTS The following procedure is recommended for making a viscosity measurement.
  • Page 21 NOTES: 1. Lock the cone tightly into the adapter. 2. When measuring volatile samples such as paints and coatings, and when using either a high temperature CAP 1000+H or CAP 2000+H, the solvent trap must be put in place over the cone to prevent the test sample from drying out during the rotation of the cone.
  • Page 22 Making Viscosity Measurements Read the results of the sample test on the printer or write down the test conditions and viscosity results from the viscometer display. 10. Relocate the solvent trap onto the cone adapter and raise the handle. 11. It is recommended to remove the cone for cleaning. However, with care, the cone can be cleaned in place.

  • Page 24 Appendix A SAMPLE SIZE It is necessary that sufficient sample is placed between the cone and plate to completely cover the surface of the cone when the cone is locked in the RUN position. With sufficient sample, an excess of about 1 mm in width will be seen around the periphery of the cone edge. For calibration and best reproducibility of results, the sample sizes shown in Table A1 should be used.

  • Page 26: Appendix B - Calibration Procedures

    When verifying the calibration of the CAP 1000+, the instrument and viscosity standard fluid error must be combined to calculate the total allowable error. The CAP 1000+ accuracy is defined in Section III.1 as a function of spindle number 03. BYK-Gardner Viscosity Standards Fluids are accurate to (+/-) 1% of their stated value. EXAMPLE: Calculate the acceptable range of viscosity using CAP 1000+ with Spindle 03 at 900 RPM; Standard Fluid CAP-3L with a viscosity of 350 cP at 25°C:...
  • Page 27 Appendix B CONE CALIBRATION A special feature of the CAP Series Viscometers allows the user to perform a cone calibration using Viscosity Standard Fluids. This field calibration will accommodate any wear on the tip of the cone which may result from contact with the plate. NOTE: A cone calibration should be performed when: 1) using a new cone for the first time, 2) switching between two cones of the same number and 3) verification of calibration provides data outside of the acceptable range.
  • Page 28 CUSTOM SPINDLES The CAP Series Viscometer allows for the use of custom spindles. Please contact BYK-Gardner’s Technical Sales Department for more information. Custom spindles are calibrated using spindle entry codes 11-20. The calibration of a custom spindle requires the entry of two parameters: SMC and SRC. The SMC and SRC are required for proper calculation of viscosity.

  • Page 29: Appendix C - Variables In Viscosity Measurement

    Appendix C APPENDIX C - VARIABLES IN VISCOSITY MEASUREMENTS As with any instrument measurement, there are variables that can affect a Viscometer measurement. These variables may be related to the instrument (Viscometer), or the test fluid. Variables related to the test fluid deal with the rheological properties of the fluid, while instrument variables would include the Viscometer design and the spindle geometry system utilized. RHEOLOGICAL PROPERTIES Fluids have different rheological characteristics that can be described by Viscometer measurements. We can then work with these fluids to suit our lab or process...
  • Page 30 Appendix C VISCOMETER RELATED VARIABLES • Most fluid viscosities are found to be non-Newtonian. They are dependent on Shear Rate and the spindle geometry conditions. The specifications of the Viscometer cone and plate geometry will affect the viscosity readings. If one reading is taken at 400 rpm, and a second at 1,000 rpm, the two viscosity values produced may be different because the readings were made at different shear rates.

  • Page 31: Appendix D - Warranty Repair And Service
