2 MCR Evolution - An Overview
The Modular Compact Rheometer Evolution series
incorporates an EC-motor with air bearings and is
designed for a wide range of measurement tasks.
Temperature control and sample-specific accesso-
ries adapt the instrument to the desired application.
The rheometer software together with Toolmaster
(the automatic recognition and configuration sys-
tem) provide a user-friendly interface.
All mechanical and electrical control components
are incorporated into one unit. The movable mea-
suring head ensures sufficient space for sample
loading and trimming.

Fig. 4: PP50 measuring geometry
Anton Paar's MCR measuring geometries can be
used with all suitable temperature devices and are
interchangeable within their category of accesso-
ries. For example, a PP 25 parallel-plate measuring
geometry can be used with all plate accessories,
like the LTD (Liquid Temperature Device), PTD
(Peltier Temperature Device), ETD (Electric Temp-
erature Device) or CTD (Convection Temperature
Device) systems. All geometry dimensions, safety
limitations and calibration constants are saved in
the Toolmaster chip located in the shaft of every
measuring geometry. Made from various materials
and featuring different surfaces and dimensions, all
measuring geometries are optimized regarding
compliance, thermal expansion and thermal con-
ductivity.

TruGap™ measures the gap and precisely adjusts
to the required position, compensating for tempera-
ture and thermal expansion. The TruGap™ function
requires dedicated accessories marked with TG in
the abbreviation.
The T-Ready™ feature employs the TruGap™func-
tionality to determine precisely when the required
sample temperature is reached. TruGap™accesso-
ries and measuring geometries are required.
The SmartPave is a dynamic shear rheometer for
the measurement of the rheological properties of bi-
tumen and asphalt. The instrument fully complies to
international bitumen standards such as AASHTO,
ASTM, DIN and others. It is possible to equip Smart-
Pave with a temperature cell with a lower Peltier
plate and a Peltier hood. This combination minimiz-
es temperature gradients in the sample and guaran-
tees reliable measurements with extreme accuracy.

4 Installing the Instrument
4.1 Installation Requirements
The setup location and surroundings should meet
the requirements of a typical laboratory (see below
and Appendix A).
Allow the equipment to reach ambient temperature
before installation. This is very important, if the
equipment has been stored or transported at lower
temperatures.
Place the instrument on a stable, flat lab bench
which is free of vibrations:
- leave at least 0.5 m space above the MCR
- leave enough space to the left of the instru-
ment, so that the power switch can easily be
accessed
To ensure temperature stability and trouble-free
measurement, never locate the MCR:
- next to a heating facility
- near an air conditioning, ventilation system
or an open window
- in direct sunlight
• Keep the instrument away from vibrations (e.g.
caused by other instruments on the same lab
bench).
• Keep the instrument away from magnetic fields.
• For best results we recommend to operate the
MCR in an air-conditioned room at a constant
temperature.
• Read the Safety Instructions in section 1.
• Find all Technical Data in Appendix A.
4.1.1 Fluid Circulator
Choice of Cooling Fluid:
There are various different use-cases for cooling flu-
ids and the correct choice of the coolig fluid depends
on them:
• Temperature control of Measuring Drive: Mix-
ture of water and antifreeze as defined in this
manual.
• Cooling, counter-cooling or temperature control
of Temperature Devices and other Accesso-
ries: Mixture of water and antifreeze as defined
in this manual or other relevant manuals.
• High temperature requirements: H20S fluid as
defined in the relevant manuals.
• Low temperature requirements: H5 fluid as
defined in the relevant manuals.
Recommended antifreeze:
Recommended antifreeze with corrosion protection
are BASF G30, G40 and G48 or equivalent products
of other suppliers.
See Appendix A for information about the choice of
cooling liquid.
CAUTION
Moving parts.
There is a risk of body parts being jammed
between the upwards moving measuring head
and other objects above the MCR.
Maintain a clearance of at least 50 cm above the
MCR.
CAUTION
Heavy object.
The MCR is heavy (up to 60 kg with accesso-
ries), therefore adequate lifting by two persons is
required to prevent injuries and instrument dam-
age. Never lift the MCR by its head.
There are recessed grips at the bottom of the
instrument (Fig. 2, r), which should always be
used to lift the MCR.
NOTICE
Do not remove the transport protection before
you have connected a suitable air supply with air
quality according to ISO 8573-1, class 1.3.1.
NOTICE
Always mount the MCR protection tube to pro-
tect the coupling of the measuring drive and the
measuring drive when the MCR is not in use.
CAUTION
Highly inflammable
Never use ethanol or any other low-viscosity sol-
vent as coolant. The rheometer’s quick cou-
plings are not sufficiently solvent-proof.

4 Installing the Instrument
20 C92IB046EN-C
For circulators offered by Anton Paar (except for
the Julabo AWC100):
• Use a mixture of 60 % distilled, deionized water
and 40 % concentrate of engine coolant anti-
freeze with corrosion protection suitable for alu-
minum.
• In case of evaporation of the coolant, refilling
must always be carried out with the correct mix-
ing ratio of 60:40.
• Verify the pH-value of the coolant in intervals of
two months in order to ensure a stable, neutral
quality between pH = 7 and 9.
If the pH value drops below pH = 7, the coolant
mixture must be changed immediately. The
addition of pH-increasing agents is not permit-
ted.
• Dispose of the coolant according to the instruc-
tions on the manufacturer's safety data sheet.
• In the case of a blockage in the cooling circuit,
contact an AP service technician immediately.
For the Julabo AWC100 circulator:
• Use a mixture of 90 % distilled, deionized water
and 10 % concentrate of engine coolant anti-
freeze with corrosion protection suitable for alu-
minum.
• In case of evaporation of the coolant, refilling
must always be carried out with the correct mix-
ing ratio of 90:10.
• Verify the pH-value of the coolant in intervals of
two months in order to ensure a stable, neutral
quality between pH = 7 and 9.
If the pH value drops below pH = 7, the coolant
mixture must be changed immediately. The
addition of pH-increasing agents is not permit-
ted.
• Dispose of the coolant according to the instruc-
tions on the manufacturer's safety data sheet.
• In the case of a blockage in the cooling circuit,
contact an AP service technician immediately.
4.1.2 Installing Flow Indicators
To check if the fluid circulator is working properly
and the fluid’s quality is appropriate, we recommend
installing flow indicators (p/n 93035, delivered with
circulators purchased from Anton Paar).
Make sure the circulator is turned off. Cut the outlet
hose of the circulator at a point where the flow indi-
cator will be clearly visible at all times. Mount the
flow indicator between the two hose ends with the
supplied hose clamps.
The coolant flowing through the flow indicator
should be clear and devoid of visible particles at all
times.
4.2 Software Installation
You will find a USB-storage device in the box of the
MCR. This USB-storage device contains all re-
quired software and some additional information.
Install the RheoCompass software on the PC that
will be connected to the MCR according to the in-
structions that were delivered with the software.
To install RheoCompass on the PC, insert the instal-
lation USB storage device and follow the instruc-
tions you will find on the USB device.
NOTICE
Damage caused by unsuitable cooling water
quality.
• Hard water is not suitable for temperature
control because it leads to calcification.
• Ferrous water will cause formation of rust
even in instruments made of stainless steel.
• Water must not contain chlorine or added
minerals. Chlorinated water will cause pitting
corrosion.
• Due to their corrosive characteristics, pure
distilled water and deionized water are
unsuitable as open circuit cooling fluids.
• Avoid microbiological proliferation in the bath
water as organic particles can clog the instru-
ments.
NOTICE
Risk of damage
Handle with care. Don’t overstrain the flow indi-
cators. Check for leak-tightness after mounting.
