I. INTRODUCTION The CAP 1000+ Series Viscometers are high shear rate instruments with Cone Plate geometry and integrated temperature control of the test sample material. Rotational speeds include 750 RPM and 900 RPM. Viscosity measurement ranges depend upon the cone spindle and the rotational speed (shear rate). Viscosity is selectively displayed in units of centipoise (cP), poise (P), milliPascal seconds (mPa•s) or Pascal seconds (Pa•s).
The following optional items may have been included: 7. Viscosity Standard Fluid for calibration Part No. See Table III-5 and III-6 in Section III. Please check to be sure that you have received all components and that there is no damage. If you are missing any parts, please notify Brookfield or your local dealer immediately. Any shipping damage must be reported to the carrier.

3) Verify that the viscometer’s power requirements match your power source BEFORE connecting it to power. The AC input voltage and frequency must be within the appropriate range as shown on the back of the viscometer head . Note: The CAP Viscometer must be earth grounded. Use the three (3) wire power cord! Do not alter! 4) Connect the power cord to the viscometer and to the power supply (source). 5) If using a printer, connect the printer cable to the printer port and printer.
I.6 Key Functions Figure I-3 shows the control keys on the face of the viscometer display panel: NUMERIC 0 - 9 These keys are used for data entry ENTER This key accepts entered data. STOP / ESCAPE Stops cone spindle rotation at any time. Exits data entry field. DELETE This key clears entered values for input selections. PRINT This key sends data to the parallel printer, when connected. RUN This key starts spindle rotation. RUN TIME This key selects time entry mode (time of spindle rotation).
I.8 Cleaning Instrument, Keypad & Painted Surfaces: Clean with dry, non-abrasive cloth. Do not use solvents or cleaners. Immersed Components (spindles/cones) and temperature controlled plate: All immersed components are made of carbide steel. Clean with non-abrasive cloth and solvent appropriate for sample material that is not aggressive to immersed components. Do not use metal objects to clean the plate surface, as scratching of the plate may occur and compromise cone calibrations.
II. GETTING STARTED II.1 Power ON 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). MAIN SCREEN 0.00P 0.0% Run 15 50.0C Spindle 04 900 RPM Figure II-1 The instrument will be set to the default temperature. CAP L Series Viscometer CAP H Series Viscometer 25.0°C 50.
When using the solvent trap (Figure II-2), connect it to the cone adapter by sliding it up, passing the slot by the thumb screw and turning the trap clockwise onto the thumbscrew. Slide the cone up into the adapter as far as it will go and hand lock it in place with the thumb screw. Tighten the thumb screw firmly and securely. Thumb Screw Cone Spindle Solvent Trap Figure II-2: Cone Attachment Press the SPINDLE key. The display will change to the spindle entry screen.
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). 2. A special feature of the CAP series viscometers allows the user to perform a cone calibration with viscosity standard fluids. 3. Cones entered as 11 through 99 must be first calibrated following the directions in Section III.
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. Brookfield recommends using the solvent trap at all times to enhance the temperature control of the sample material. After inserting the sample material onto the plate, lower the spindle and solvent trap and allow sufficient time for thermal equilibrium prior to starting the test.
A maximum of 999 seconds can be printed when running in manual TIMER mode (00). Over 999 seconds will print EEE. 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. At the end of a test, data will automatically be sent to the printer port. II.8 Run and Stop Keys The RUN key has three functions: 1. Press RUN to begin a test. 2.
III. OPERATION The CAP 1000+ Viscometer is delivered from the factory with two available speeds for operation at 750 rpm or 900 rpm. Information on how to access these speeds is detailed in section II.3 “Speed Setting”. Your viscometer may operate at a different rotational speed based on what was specified at the time of order. To determine what speed your viscometer has been set to, power on the viscometer and note the operating speed on the main screen display. III.

• In ambient conditions outside of 15°C to 30°C, accuracy is +/- 2.0°C when the temperature set point on the viscometer is 50°C to ≤100°C. III.3 Calibration Verification Accuracy of the CAP 1000+ Viscometer can be verified by performing a calibration verification. The cones/spindles that were shipped with the viscometer were calibrated to the viscometer by Brookfield prior to shipment.

III.4 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.
Note: The calibration process may be cancelled at any time prior to pressing RUN by pressing the ESCAPE key. When calibration is complete, spindle rotation will stop and the “CALIBRATION COMPLETE” screen is displayed. (See Figure III-2). Press ENTER to continue. CALIBRATION COMPLETE PRESS ENTER TO CONTINUE If the viscometer is connected to a printer, the printout (Figure III-3) will automatically be generated. There will be values for the listed variables.
III.6 Making Viscosity Measurements The following procedure is recommended for making a viscosity measurement. With the viscometer on a clean, level surface, connect it to the proper power supply (Section I.4). 1. Turn the power switch ON (Section II.1). The procedure assumes that the following have been done: a) If the viscometer has been “off” for an extended period (i.e., overnight) a “warm up” period of 30 minutes is suggested. You may choose to warm up at the temperature of test.
Notes: a. b. c. Lower the handle gently. DO NOT FORCE THE CONE ONTO THE PLATE. The sample must completely cover the face of the cone and extend beyond the edge of the cone about 1.0 mm. Release the solvent trap placing it onto the plate over the cone so it does not touch the cone shaft. The user should ensure that the substances placed under test do not release poisonous, toxic or flammable gases at the temperatures to which they are subjected to during the testing. 7.
APPENDIX A - 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.
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. For example, if one reading is taken at 750 rpm, and a second at 900 rpm, the two viscosity values produced may be different because the readings were made at different shear rates. The faster the spindle speed, the higher the shear rate.
APPENDIX B - Warranty Repair and Service Warranty Brookfield Viscometers are guaranteed for one year from date of purchase against defects in materials and workmanship. They are certified against primary viscosity standards traceable to the National Institute of Standards and Technology (NIST). The Viscometer must be returned to Brookfield Engineering Laboratories, Inc. or the Brookfield dealer from whom it was purchased for warranty service. Transportation is at the purchaser’s expense.
