1.3 Information concerning the CE sign
Thermo Scientific electrical equipment for measurement,
control and laboratory use bears the CE marking.
The CE marking attests the compliance of the product with
the EC-Directives which are necessary to apply and confirms that the apparatus meets all relevant essential requirements of the directive, the defined relevant protection
requirements.
The conformity assessment procedures were performed
following a defined methodology according to each applicable directive.
The council decision 93/465/EEC shall be authoritative
concerning the modules of the various phases of the conformity assessment procedures and the rules for the affixing and use of the CE marking, which are intended to be
used in the technical harmonization directives.
To confirm compliance with the EC-Directive 2004/108/EC
Electromagnetic Compatibility (EMC) our product was tested according to the EMC requirements for emission and
immunity for electrical equipment for measurement, control and laboratory use.
Compliance with the protection requirements areas (domestic establishments and establishments directly connected to a low voltage power supply network which supplies buildings used for domestic purposes) and industrial
areas is ensured.
Our strict standards regarding operating quality and resulting considerable amount of time and money spent on development and testing reflect our commitment to guarantee the high level of quality of our products even under extreme electromagnetic conditions.
Practice however also shows that even electrical equipment which bears the CE marking such as monitors or
analytical instruments can be affected if their manufactures accept an interference (e.g. the flickering of a monitor)
as the minimum operating quality under electromagnetic
compatibility phenomena. For this reason we recommend
you to observe a minimum distance of approx. 1 m from
such equipment.

5. Safety Notes and Warnings
The Rheometer corresponds to the relevant safety regulations. However you are solely responsible for the correct
handling and proper usage of the instrument.
This instrument exclusively determines the rheological behavior of fluid and half-solid materials. These materials may not
be tested if people can be hurt or devices be damaged.
Do not lift or move the unit at the ends of the glass pane.
Do not measure / temperature control any materials that
may give off dangerous vapours or may be inflammable
within the working temperature range of the rheometer.
The device may not be operated if there are any doubts
regarding a safe operation due to the outer appearance
(e.g. damages).
A safe operation of the instrument cannot be guaranteed if the user does not comply with this instruction
manual.
Ensure that this instruction manual is made readily
available to every operator.
Do not bend connection and/or mains cable, do not
subject cables to stress or high temperatures (higher
than 70 C).
Check cables visually at regular intervals.
The operator must have an uninterrupted view of the
machine and its surroundings.
The rheometer must be fully visible from the PC control stand.
This unit should only be used for the applications it was
designed for.
The rheometer is designed for use with a rotor. All existing safety devices are based on the correct installation
of the rotor. Is the lift (of the measuring table) used without a rotor installed injuries may occur when reaching in
the lift area.
Make sure that the unit has been switched off before you
connect or disconnect the cables. This is to avoid electrostatic charging resulting in a defect of the electronic
circuit boards.

Once the probe attains appropriate viscosity,cylindrical
tube (Order no. 222--1394) protectors that prevent
probe’s radial exit must be used when measuring. An
operational error when using the measuring device can
lead to the probe’s radial exit from the measuring gap; it
is therefore recommended to wear protective goggles.
Do not operate the unit with wet or oily hands.
Do not immerse the unit in water or expose it to spray
water.
Do not clean the unit using solvents (fire danger!) -- a
damp cloth applied with a household cleaning substance is often sufficient.
Complete separation from the mains is required when
repairs or maintenance work is about to be carried out.
Suitable personal protective gear, consisting of lab
coat, protective eyewear and safety gloves, must be
worn at all times when working with the instrument
Repairs, alterations or any work involving opening up
the unit should only be carried out by specialist personnel. Considerable damage can be caused by incorrect
repair work. The Thermo Fisher Scientific service department is at your disposal for any repairs you may require.
Have the unit serviced by specialists at regular intervals.
RheoStress1: The pressure of the air supply for the air
bearing must not exceed 4 bar. Higher pressure will
damage the air bearing permanently!
For applications at elevated temperatures above 250C
it is a must to switch the fan for the air bearing cooling
on stage 2 (on the rear) and use ceramic shafts only.
Furthermore use the cone heater TC1 as thermal shield
to prevent the heating up of the air bearing housing!
Severe skin burns can be caused by contact with hot
unit parts!
The rheometer can reach temperatures up to 350 C, depending on the temperature control unit installed. This can result
in parts of the rheometer heating up to such an extent, even
when taking the cooling and insulation into account, that serious burns can result if they come into contact with the skin.
Thermo Fisher Scientific recommends shielding the rheometer when operating at high temperatures and handling it only
with high temperature proof gloves and safety glasses.
A danger symbol on the glass plate warns the user of possible danger (burn injury).

6.3 Space Requirements
Good working conditions for a complete installation require
an area of about 1 x 0.6 meters. The two benches should be
rigid with a level surface and easy to clean. The circulator
used for temperature control should be located below the
rheometer on a separate bench to avoid backflow of thermal
fluid and possible mechanical oscillation.
A suitable laboratory bench must be provided for
the installation.
The circulator has to be located below the level of
the rheometer, otherwise the thermal fluid flows
back in the cup holder and flushes the instrument.
6.4 Mains supply
Only attach the units to mains sockets with a
grounded earth. Compare the local mains voltage
with the specifications written on the name plates
of the measuring instrument and the control unit.
Voltage deviations of 10 % are permissible.
Mains cable and unit fuses:
1
Use the mains cable according to your local mains voltage ( see chapter “Contents of delivery”).
2
Insert the fuses according to your local mains voltage
below the mains connection 6.

6.6 Requirements for the air supply
HAAKE RheoStress RS1 / RW1F
Pure air pressure is connected at nozzle for the air bearing
with a pressure by 2.5 bar (ideal way).
The air supply must have the following conditions:
-- max. 4 bar,
-- consumption approx. 10 dm3/minute
(1 dm3= 1 thousandth of a cubic meter),
-- no synthetic oil in the line,
-- max. oil contents 3mg/m3air,
-- dry air with a residual moisture < 40 %
Use the filter unit (order no. 222-1211) or the HAAKE
compressor (order no. 222-1434 for 230 V and 222-1435 for
115 V).
HAAKE RheoStress1: The pressure of the air supply for the
air bearing must not exceed 4 bar. Higher pressure will damage the air bearing permanently!
The air bearing reacts highly sensitive to dirt like particles (dust an
lint) or liquids (oil or water which condenses at high humidity levels). It is therefore recommended to have new air compressors run
for a longer period of time (0,5 hrs.) without actually connecting
it to the Rheometer. In the case of internal supply systems polluted
air might have collected near the connection nozzle when the line
has not been used for some time. Therefore, we also recommend
to ”flush” this line for a period of approx. 0.5 hrs.
6.7 Pipes in the building
Oil is generally applied to air pipes in the buildings of materialprocessing plants in order to prevent rusting in the workshops. By
means of complex filters the oil content may be reduced by rarely
so much that the air bearing does not suffer damage.
Thermo Fisher Scientific air bearings must not be used in plants in
which oil is added.
6.8 Air compressors
There are ”oil-free” and ”lubricated” versions of air compressors.
Only oil-free compressors (e.g. the HAAKE compressor) are admissible for Thermo Fisher Scientific air bearings.
If the hose length is larger then 5 m (between compressor and
measurement unit), it must be separately attached pressure controller located next to the measurement unit (see instruction
manual Air compressor Carat).
6.9 Ambient conditions according to EN 61010
It is recommended to run tests in an air-conditioned room,
(T = approx. 23 C):
indoors, max. 2000 meters above sea level,
ambient temperature 15 ... 40 C,
relative humidity max. 80%/31 C( 50%/40 C)
excess voltage category II, contamination level 2

7. Unit Description
lntroduction
The viscoelastic behavior of a fluid or a soft solid can be characterized in two ways; either the fluid is deformed and the resulting stress is measured (CR mode), or the stress is applied and the deformation monitored (CS mode). The principle benefits of the CS mode are:
Software
Software control and evaluation with HAAKE RheoWin or
OS1 to program the display unit for production laboratories.
Measurements and evaluation
The Rheometers is controlled either by the HAAKE RheoWin Software or with one of 10 pre--programmable measuring procedures by the display unit. The results are available for further processing on a PC with the HAAKE RheoWin Software. Alternatively up to 50 measurements can be
stored internally and be evaluated, displayed or printed out
for documentation purposes.
Sensors
For HAAKE RotoVisco1 and HAAKE RheoStress1 plates,
cones, coaxial cylinders and immersion systems are available.
Unit Description
17
7.1 HAAKE RotoVisco1
Thixotropy and flow curve
The determination of the flow behavior of a test substance
requires a speed ramp up, a holding time and a return curve
for the determination of the thixotropy. This hysteresis
method can like all other measuring procedures be PC controlled or can be loaded as procedure in the display and control unit.
Time curve
Is the viscosity of a test substance changing with time this
can be monitored objectively with the HAAKE RotoVisco1.
This is especially important for substances which are curing
(adhesives, building materials), change their viscosity with
storage time or show considerable changes of viscosity after
shearing during the production process (cosmetics, paint,
food).
Temperature programs
Temperature programs are very time consuming when the
rheometer has to be operated and supervised. With the RotoVisco1 these tasks can be taken over by the PC which controls t he rheometer as well as the temperature control units
-- everything without intervention of the operator.
Determination of the yield point
As soon as substances are strained beyond the Hookean
range they start to flow. This can be defined as yield point
and is an important characteristic value in quality control.
With the HAAKE RotoVisco1 this value can be established
relevant to practical applications, fast and easily by applying
a small deformation through extremely low speed values.
CD Mode
In the CD mode (speeds lower than 0.1 min
–1
) it is only measured at constant speeds. When ramps or steps are preset,
the following speed table is run:
Speed ( min
–1
)
0.0125
0.0250
0.0375
0.0500
0.0630
0.0750
0.0875
0.1000
Unit Description
18
7.2 HAAKE RheoStress1
Flow curves
in CR and CS mode can be recorded as ramp or steps
(steady state).
Time curves
for reactions (e.g. curing) at constant temperature, shear
rate, shear stress or frequency.
Temperature programs
are software controlled to determine the temperature dependence with controlled shear stress, shear rate or frequency.
Yield points
can be determined with creep/recovery tests or with stress
controlled ramps.
Viscoelasticity
of a fluid can be quantified by a creep/recovery test or by dynamic measurements in CD (Controlled Deformation) or CS
(Controlled Stress) mode.
Multiwave
even allows the determination of the frequency spectra as a
function of time or temperature by overlay within shortest
time.

7.3 Temperature control:
For applications at elevated temperatures above 250C
it is a must to switch the fan for the air bearing cooling
on stage 2 (on the rear) and use ceramic shafts only.

Quick fitting sensor with a high precision even if not
perfectly clean.
Remote and manually controlled lift with variable
speed to preserve the fluid’s structure and ensure
reproducible test conditions.
Microprocessor controlled positioning of the sensor to
ensure the highest accuracy for routine tests.
Standard temperature range of --40 to 250 C using a
heating circulator; utilizing electrical cone heating
extends this up to 350 C.
Controlled rate mode for characterizing rheologically
complicated fluids (HAAKE RotoVisco 1 and HAAKE
RheoStress 1).
Controlled stress mode for characterizing sensitive
substances (HAAKE RheoStress1).
Forced oscillation tests at very low frequencies and
very low strains allow destruction free measurements
(HAAKE RheoStress 1).
Sophisticated application software packages with
userfriendly window menus and an on-line help key.

8. Installation
8.1 Setting up the Rheometer
Lift the Rheometer out of the package and place onto a
stable, level table. Do not lift the unit at the glass pane or
at the measuring head ! For sensible measurements a
plane table is recommended.
In the base of the measuring instrument, there are four feet
which can be screwed in or out for levelling the unit.Upon
completion of the preliminary visual levelling, exact precision
levelling can be carried out using the spirit level supplied.
1
The spirit level:
is put on the measuring plate at temperature control
unitTCL/P;TCE/P;TCE/PCandTCP/P.
is put into connection with a vessel at temperature con-
trol unit TCL/Z.
is put on the measuring plate in the vessel at tempera-
ture control unit SHRP.
is not used at temperature control unit TCO.
2
Adjust the feet so that the air bubbles remain in the center of the spirit level.
This adjustment process should be repeated at least once a
week.

8.3 Hose connections
8.3.1 Temperature control unit (with liquid):
The temperature control unit with liquid temperature
control is connected with hoses to a heating bath and
circulator.
While fastening the hose connections at the connecting nozzles (14) of the temperature control unit
the connecting nozzles must be held up by
wrenches.
Direction of flow of the liquid
Temperature range up to 150 C:
Viton hoses
Hoes nozzle -Set 222--1492
Temperature range of 100 Cupto350 C:
Metal hoses 333-0294
Hoes nozzle -Set 222--1492
Liquid temperature control:
Temperature range up to 100 C:
Thermal liquid in the temperature range between --50
C and 30 C: water with anti-freeze.
Temperature range from 5 Cto90 C: distilled water.
Distilled water
Normal mains water causes cable deposits and
frequently requires the unit to be descaled.
In principle, water up to 95 C can be used. However,
above 80 C, so much water evaporates that it requires
frequent topping--up.
Water with anti--freeze
If you intend working at temperatures below 5 C,
anti--freeze must be added to the water. The added
amount of anti--freeze should be sufficient for a
temperature that is about 10C lower than the intended
working temperature. This prevents the freezing of
water on the evaporator coil of the cooling circuit, the
surface of which is always much colder than the

working temperature. However, too much anti--freeze
worsens the temperature constancy due to its high
viscosity.
Temperature range from 100 Cto200 C:
Silicone oils or other suitable liquids are used as thermal liquid.
8.3.2 Air bearing (measuring unit)
The air bearings of the measuring units HAAKE
RheoStress1 require cooling air at port 9
(see “Requirements for the air supply”).

9.2 External filter
An external filter is part of the standard range of items
supplied with the temperature control units for Series 1
TCP/P (Peltier-Temperature control system), TCE/P
(electrical temperature control unit), TCL/PO (liquid
temperature control unit for HAAKE RheoScope) and the
UTCP/P (Peltier-Temperature control system for HAAKE
RSXXX units). It consists of the filter itself, a plastic cone
contained inside it, and clamps.
Using this filter enables the interior of the relevant
temperature control unit to be protected against any
impurities carried in by the temperature liquid. The external
filter represents an additional protection. On the standard
model a sieve is built in to the intake of each temperature
control unit.
As shown in Fig. X, the filter is installed in the intake hose
leading into the temperature control unit between the
thermostat and the measurement instrument. The intake
and outlet directions must be noted (IN and OUT on the
filter). It is fastened with the clamps that are supplied with it.
Hoses with a diameter of 8 mm can be installed and fastened
with the clamps supplied. The plastic cone on the inside of
the filter serves as a direction of flow indicator, and its
movements show the through-flow of the tempering liquid. If
there are impurities in the filter it can be taken out, cleaned,
and used again. The use of the external filter is
recommended because any impurities can be recognised
and removed more readily than with the sieve that is built in
to the temperature control unit. The screw-in sieve (internal)
must of course be checked for impurities from time to time
in order to ensure t he functional capability of the temperature
control unit.
Order numbers:
003-5266 Screw-in sieve (internal) for TCL/P, TCP/P,
TCE/P, TCL/Z
222-1667 External filter for TCP/P, TCE/P, TCL/PO
