Perform calibration verification weekly or monthly using certified, NIST-traceable Brookfield silicone viscosity standards. Ensure the fluid standard matches the temperature profile of your typical test protocols. If the measured torque or viscosity value varies by more than ±1% of the full-scale range, recalculate the gap or contact a certified service center. Common Troubleshooting Steps Observation Potential Cause Corrective Action Sample drying out or skinning Reduce test time or use a sample cover. Torque Overload (>100%) Viscosity too high for selected cone/RPM Reduce the motor speed or switch to a higher-numbered cone. Temperature Fluctuation Blocked Peltier cooling fan vents Clear dust from rear vents; ensure 6 inches of clearance. Negative Viscosity Readings Incorrect or omitted Autozero step
you are having with the viscometer (e.g., error code, calibration failure)?
: The CAP 2000+ features built-in temperature regulation. The manual details how to set targets, manage stabilization wait times, and handle solvent evaporation during high-temperature testing.
: You can find all current manuals on the AMETEK Brookfield Online Store .
: Gently pull the handle down to the lowest position to place the spindle in contact with the sample and plate. 3. Running a Test BROOKFIELD CAP 2000+ cap 2000 viscometer manual link
Asphalt, chocolate, composite polymers, epoxies, and roofing compounds. Operational and Maintenance Basics
This software allows you to generate complete rheological profiles, apply mathematical models (like the Bingham Plastic model for yield stress), and automate repetitive QC tests.
The CAP 2000+ Viscometer bridges the gap between high-shear production testing and precise laboratory research. It is uniquely engineered to handle high-shear applications where sample volume is limited.
Preheating the instrument for 30 minutes is recommended if it has been off for an extended period. : manage stabilization wait times
Quick Access to the Manual Link You can download the full, official AMETEK Brookfield CAP 2000+ Viscometer Operations Manual directly from the manufacturer's server. This document (Manual No. M02-313) provides comprehensive guidance for the installation, programming, calibration, and maintenance of the CAP 2000+ series cone and plate viscometers. Introduction to the CAP 2000+ Viscometer The AMETEK Brookfield CAP 2000+ Go to product viewer dialog for this item.
Set the desired temperature via the controller and allow the unit to stabilize.

: 5 RPM to 1000 RPM (adjustable in 1 RPM increments). Shear Rate Spectrum : From 10 sec-1sec to the negative 1 power sec-1sec to the negative 1 power ensure 6 inches of clearance.
is a cone and plate viscometer designed for medium to high shear rate measurements.
: Ensure the spindle and plate reach thermal equilibrium before adding your sample. Automatic Positioning
: Press the TEMP key and enter your set point using the number keys. High-temperature models (H series) range from 50–235°C, while low-temperature (L series) range from 5–75°C. 2. Spindle Installation & Sample Loading
Turn on the viscometer and allow it to complete its self-test. Select the appropriate cone spindle based on expected viscosity.
