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 ship- ping damage must be reported to the carrier. Save the packing container, if possible, for future use when returning the viscometer to Brookfield or an authorized dealer for service. - Page 5 Temperatures: CAP 2000+L 5°C (or 15°C below ambient, whichever is higher) to 75°C CAP 2000+H 50°C to 235°C All models provide 0.1°C increments Weight: Gross Weight 36 lb 16.3 kg Net Weight 27 lb 12.3 kg Carton Volume 4.9 cu ft 0.15 m...

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. Note: Ensure that both the printer and the CAP 2000+ are off when connecting cables. Brookfield Engineering Labs., Inc. Page 7 Manual No. M02-33E209... -
Page 8: Safety Symbols And Precautions
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 Manual No. M02-33E209... -
Page 9: Key Functions
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. Brookfield recommends a minimum torque reading of 10% when making viscosity measurements. If the torque value is between 0 and 10%, the display will flash to indicate an under range condition. -
Page 10: Cleaning
Solvent Trap (P/N C1K-63) is made of Teflon. Clean with non abrasive cloth and solvent appropriate for sample material that is not aggressive to Teflon. When cleaning, take care not to apply excessive force which may bend the spindle shaft or otherwise damage the instrument. Brookfield Engineering Labs., Inc. Page 0 Manual No. M02-33E209... -

For example: if using cone 4 (shear rate multiplier of 3.33), an entered shear rate of 51 1/SEC will be displayed as 50 1/SEC. Brookfield Engineering Labs., Inc. Page Manual No. M02-33E209... -

YES and see Section III. Cones supplied at the time of order are calibrated to the viscometer by Brookfield prior to shipment, but should still be verified with a calibration check prior to use for the first time. Cones purchased separately at a later time by the user must also be calibrated prior to making viscosity measurements. -
Page 14: Ii.4 T Emperature Control 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. Brookfield recommends using the solvent trap at all times to enhance the temperature control of the sample material. -

III. Full Scale Range and Accuracy of Measurement Full Scale Range (FSR) viscosity is the maximum viscosity that can be measured and occurs when the % torque is 100. Brookfield recommends that viscosity measurements be made be- tween 10 and 100% torque. -

HIGH TEMP UNITS: • In ambient conditions of 15°C to 30°C, accuracy is +/- 0.5°C when the temperature set point on the viscometer is 50°C to ≤100°C. Brookfield Engineering Labs., Inc.

Page 20: Iii.3 Calibration Verification
The cones/spindles that were shipped with the viscometer were calibrated to the viscometer by Brookfield prior to shipment. If your viscometer was returned to Brookfield or an authorized Brookfield Dealer, then any cones/spindles that were returned for service will have been cali- brated to the viscometer prior to shipment. - Page 21 6. If the test fails, repeat again to make sure that every step was performed correctly. If the test fails again, perform a cone calibration according to the procedure in Section III.4.

Viscosity Standard Fluids. This field calibration will accommodate any wear on the tip of the cone which may result from contact with the plate. This also allows the user to purchase a new cone spindle and perform the calibration in your plant Brookfield Engineering Labs., Inc. Page 22 Manual No. M02-33E209... - Page 23 Full Scale Range. Spindles used with the high torque CAP 2000+ and the recommended viscosity standard fluids may be calibrated at any speed. Brookfield Engineering Labs., Inc. Page 23 Manual No. M02-33E209...

Page 24: Iii.5 Repeatability
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 Brookfield Engineering Laboratories or your Brookfield Dealer/Distributor/Representa- tive for details on the above information. -
Page 25: Iii.6 Making Viscosity Measurements
Cone calibration is only required when a new cone (i.e., replace- ment for lost/damaged cone) is used, or when calibration check fails. c) When making measurements with low temperature instruments (CAP 2000+L), the solvent trap may not be required (for the containment of solvents and/or prevention of sample “drying”). -
Page 26: Iii.7 Computer Control
The CAP 2000+ Viscometer can be operated remotely under PC control when using the CAP- CALC application software. When advanced sample analysis is required, Brookfield CAPCALC application software can control the CAP 2000+ Viscometer from a PC. CAPCALC for Windows requires Windows Brookfield Engineering Labs., Inc. - Page 27 5°C and 75°C (CAP 2000+L) or 50°C and 200°C (CAP 2000+H) depending on viscometer model. CAPCALC features include on-screen and printed plots of % F.S.R., viscosity or shear stress vs.

If you set a Viscometer at a constant speed, recording P values over time, and find that the P values decrease with time, the material is thixotropic.
