RSO™ Operator Instructions

1. INTRODUCTION

The Brookﬁeld RSO Rheometer is a rotational and oscillatory controlled-stress rheometer used

in quality control, product development, and research. The measuring drive developed for this

instrument utilizes a high precision dynamic drive system with an optical encoder for absolute position

measurement of spindle deﬂection.

There are four basic methods of measurement available with the RSO Rheometer:

• Rotational measurement under controlled shear rate (CSR)

• Rotational measurement under controlled shear stress (CSS)

• Oscillatory measurement under controlled shear stress (CSS)

• Oscillatory measurement under controlled deformation/strain (CD)

The RSO Rheometer has all the functionality of a standard Brookﬁeld rotational viscometer,

performing rotational tests with pre-set speed or shear rate. The RSO Rheometer is even more

versatile because it can also perform tests with a pre-set torque or shear stress and measure the

resulting shear deformation of the test substance via angular deﬂection of the measuring element.

The RSO controlled stress capabilities can be used for experiments such as:

(1) Measurement of the “static” yield stress – eliminating the multi-shear rate test that requires

math model extrapolation; and

(2) Creep and Recovery of numerous materials.

Additionally, the RSORheometer is equipped with a powerful motor with a usable torque range of

0.005 to 100 milliNewton-meters, mN-m or mNm. As a result, the RSORheometer is appropriate for

rheological measurements over a wide range of sample viscosities. Furthermore, the oscillatory mode

measures viscoelastic material responses that cannot be measured in rotational tests. One advantage

of small-amplitude oscillatory rheometry or “SAOS” is that the small strains or deformations can

probe weak structures without destroying them (e.g., testing weak gels, etc.)

The Brookﬁeld RSORheometer incorporates the following features:

• Air-bearing, drag cup motor, capable of both rotational and oscillatory measurements.

• Digital control of rotational speed, shear rate, torque, or shear stress.

• Pre-designed rotational measurement programs for analysis of viscosity ﬂow curves, creep

and recovery behavior, yield stress, and thixotropic properties.

• Pre-designed oscillatory test methods: amplitude sweep, frequency sweep, time-dependent

or temperature-dependent behavior.

Page 7

• Automatic adjustment of control parameters during measurement.

• Direct indication of measured and calculated values of speed, shear rate, torque, shear

stress, shear strain, viscosity, temperature, and time.

• Graphical display of measured results in real-time.

• The internal storage of data, including test parameters, measured values, and calculated

values.

• User interface via a touchscreen display.

• Quick-connect coupling system for easy spindle attachment.

• Barcode reader for automatic spindle recognition.

• USB port for connection to a computer or a USB ﬂash drive.

• Operation in standalone mode via touchscreen display or with a computer system running

Rheo3000 application software.

• Dual Conﬁguration Modes to allow for Cone, Plate, and Coaxial Cylinder Spindles and

Accessories. *

*Measuring Systems (hereinafter referred to as “Spindles”) and Accessories are not part of the standard

delivery of the RSORheometer and must be ordered according to the user’s measuring requirements.

The following additional services are available to support the use of the RSORheometer:

• Start-up Assistance

• Instrument Training

• Rheo3000 Software Training

• IQ/OQ/PQ (Installation, Operation, and Performance Qualiﬁcation)

1. 1 Obligation to Instruct

The RSORheometer should only be operated by qualiﬁed personnel.

Please read the operating instructions before using the instrument.

1. 2 Safety Information

Read the operating manual carefully, follow all instructions provided, and observe all safety

notes to ensure the proper and safe use of this measuring instrument. If you have any questions,

please contact AMETEK Brookﬁeld Technical Support or an authorized dealer.

Page 8

This instruction manual uses the following safety notes and symbol categories:

Warning ... a situation which may result in injuries to people or damage to property, environment,

software, data, or test results if ignored. The warning must be strictly observed.

Mandatory ... an important precaution.

Info ... important or useful comments and information.

1. 3 Safety and Hazard Information

This instrument is not intended for use in an explosive or otherwise potentially hazardous

environment.

If RSO Rheometer is used in a manner not specied by the manufacturer, the protection measures

integrated into the instrument may be impaired.

In case of emergency, turn o󰀨 the instrument and then disconnect the electrical cord from the wall

outlet.

1. 4 General Handling and Operational Safety

When moving the RSO short distances (i.e., during Setup), ﬁrst protect the instrument by

inserting the black foam rubber stopper between the rheometer head and base. Ensure that

the sample plate is at a safe temperature. During transportation, hold the instrument only

by its base. Never hold the instrument by the head to carry it. Never lift the instrument by

the spindle or its coupling. Protect the instrument against heavy bumps, vibrations, or shocks

that might impair the rotation of the coupling. Use a rolling cart for transportation whenever

possible.

The RSO Rheometer weighs approximately 70lbs.(32kg) and requires two people to

safely lift.

Make sure that the instrument is in a clean, dry working environment (dust-free, moderate

temperature, low humidity, etc.), see section IV.2.2 Ambient Conditions.

1. 5 Dangers in Handling the Machine

Be aware of substances placed under test that may release poisonous, toxic, or ammable

gases at the temperatures which they are subjected to during the testing.

If dangerous vapors can be released by heating the material, appropriate ventilation is

required.

If ammable substances are tested, the temperature must be 25 °K below the ashpoint

of the material. In general, the ashpoint of the test sample material must not be below

+205°C (+401°F).

DO NOT touch rotating spindles. Damage to the spindle and/or RSO may occur.

Safeguard any loose-tting clothing (sleeves). Remove any jewelry, rings, watches, etc.

Protect long hair. Tie hair back or work with a cap or hairnet.

Cone and Plate Spindles can eject bits of the sample from the plate during high-speed

tests.

The user should wear eye protection and protective clothing during testing.

Wear gloves to protect against skin contact with potentially irritating or harmful substances.

High Magnetic Fields. Pacemakers or other similar implanted devices may be a󰀨ected.

Burn Hazard. Allow Sample Plate, Water Jacket, and Hoses to cool before touching or

removing them.

Electrical Hazard. Unplug damaged power from the wall outlet cord before removing from

RSO.

Laser Bar Code scanner in use. Avoid Direct Eye Exposure.

Compressed Air in use.

Class A instrument

Repair service should only be performed by AMETEK Brookﬁeld’s trained service team, see

Appendix F: Warranty and Repair.

1. 6 Ergonomics

Ensure your planned work area is at a comfortable height with a proper stool or seat.

Allocate enough space to allow for a PC and external temperature control device to be within

easy reach.

1. 7 Unpacking

The RSO Rheometer weighs approximately 70lbs.(32kg) and requires two people to
