Safety
Do not attempt to service this instrument, as it contains no user-serviceable components.
Required Equipment
While operating this instrument, you must wear eye protection that either meets or exceeds ANSI Z87.1
standards. Additionally, wear protective clothing that has been approved for protection against the
materials under test and the test temperatures.
Instrument Symbols
The following label is displayed on the instrument for your protection:
Please heed the warning labels and take the necessary precautions when dealing with these areas. This
Getting Started Guide contains cautions and warnings that must be followed for your own safety.

This symbol on the AR-G2 indicates that you should read this Getting Started
Guide for important safety information. This guide contains important warnings
and cautions related to the installation, operation, and safety of the instrument.
This symbol indicates that a hot surface may be present. Take care not to touch
this area or allow any material that may melt or burn come in contact with this
hot surface.
This symbol indicates that you are advised to consult this manual for
instructions.

Warnings
WARNING: This equipment must not be mounted on a flammable surface if low
flashpoint material is being analyzed.
WARNING: An extraction system may be required if the heating of materials
could lead to liberation of hazardous gasses.
WARNING: It is recommended that this instrument be serviced by trained and
skilled TA Instruments personnel at least once a year.
WARNING: The material used on the top surface of the Peltier Plate is hard,
chrome-plated copper and the material used for the 'skirt' of the Peltier is stain-
less steel. Therefore, use an appropriate cleaning material when cleaning the
Peltier Plate.
WARNING: The internal components of the ETC are all constructed from chemi-
cally resistant materials, and can therefore be cleaned with standard laboratory
solvents. The only exception is the cladding for the thermocouples, which
should not be immersed in a solvent for long periods. Use a small amount of
solvent on a soft cloth and wipe the soiled area gently. This procedure should
never be conducted at any temperature other than ambient.
WARNING: During the installation or reinstallation of the instrument, ensure that
the external connecting cables (i.e., data, RS232 etc.) are placed separate from
the mains power cables. Also, ensure that the external connecting cables and
the mains power cables are placed away from any hot external parts of the
instrument. Note: Ensure that the mains power cable is selected such that it is
suitable for the instrument that is being installed or reinstalled, paying particular
attention to the current rating of both the cable and the instrument.
WARNING: During operation, extreme hot or cold surfaces may be exposed.
Take adequate precautions. Wear safety gloves before removing hot or cold
geometries.

WARNING: Liquid nitrogen can cause rapid suffocation without warning. Store
and use in an area with adequate ventilation. Do not vent liquid nitrogen in con-
fined spaces. Do not enter confined spaces where nitrogen gas may be present
unless the area is well ventilated. The warning above applies to the use of liquid
nitrogen. Oxygen depletion sensors are sometimes utilized where liquid nitro-
gen is in use.
WARNING: The various surfaces and pipes of the ETC and the supply Dewar can
get cold during use. These cold surfaces cause condensation and, in some
cases, frost to build up. This condensation may drip to the floor. Provisions to
keep the floor dry should be made. If any moisture does drip to the floor, be sure
to clean it up promptly to prevent a slipping hazard.
WARNING: Always unplug the instrument before performing any maintenance.
WARNING: No user serviceable parts are contained in the rheometer. Mainte-
nance and repair must be performed by TA Instruments or other qualified ser-
vice personnel only.
WARNING: This instrument must be connected to an earthed (grounded) power
supply. If this instrument is used with an extension lead, the earth (ground) con-
tinuity must be maintained.
WARNING: Take adequate precautions prior to heating of materials if it can lead
to explosion, implosion or the release of toxic or flammable gases.
WARNING: The impeller is constructed from a rigid polymer composite material
of density about 1.6 g cm-3. It he usual operating angular speed is 160 revolu-
tions per minute, rpm, (16.76 radians per second). Under these conditions the
unit is unlikely to provide a significant hazard to the user, and only the normal
precautions observed when operating the rheometer need be taken.
The instrument software does permit operation of the rheometer at its maximum
angular speed, without immersion of the impeller. Take reasonable precautions
to avoid contact with the impeller when it is rotating at high angular speed.
Ensure that clothing, jewelry, etc. does not become entangled in the impeller.

Electrical Safety
Always unplug the instrument before performing any maintenance.
Supply voltage: 110 to 230 VAC
Fuse type: 2 x T15A H250 V
Mains frequency: 50 to 60 Hz

Liquid Nitrogen Safety
DANGER: Because of the high voltages in this instrument, maintenance and
repair of internal parts must be performed by TA Instruments or other qualified
service personnel only.
Potential Asphyxiant
WARNING: Liquid nitrogen can cause rapid suffocation without warning.
Store and use in an area with adequate ventilation. Do not vent liquid nitrogen
in confined spaces. Do not enter confined spaces where nitrogen gas may be
present unless the area is well ventilated. The warning above applies to the
use of liquid nitrogen. Oxygen depletion sensors are sometimes utilized
where liquid nitrogen is in use.
Extremes of temperature
During operation, extreme hot or cold surfaces may be exposed. Take
adequate precautions.
Wear safety gloves before removing hot or cold geometries.

Handling Liquid Nitrogen
The ETC uses the cryogenic (low-temperature) agent, liquid nitrogen, for cooling. Because of its low tem-
perature [–195°C (–319°F)], liquid nitrogen will burn the skin. When you work with liquid nitrogen, use
the following precautions:
• Liquid nitrogen evaporates rapidly at room temperature. Be certain that areas where liquid nitrogen is
used are well ventilated to prevent displacement of oxygen in the air.
• Wear goggles or a face shield, gloves large enough to be removed easily, and a rubber apron. For extra
protection, wear high-topped, sturdy shoes, and leave your trouser legs outside the tops.
• Transfer the liquid slowly to prevent thermal shock to the equipment. Use containers that have
satisfactory low-temperature properties. Ensure that closed containers have vents to relieve pressure.
• The purity of liquid nitrogen decreases as the nitrogen evaporates. If much of the liquid in a container
has evaporated, analyze the remaining liquid before using it for any purpose where high oxygen con-
tent could be dangerous.
• The oven inner doors have a trough around the bottom of the element assembly for collection of excess
liquid nitrogen. Any excess fluid collected will drain out from the oven at the lower outer edge.
If a person is burned by liquid nitrogen:
1IMMEDIATELY flood the area (skin or eyes) with large quantities of cool water, then apply cold
compresses.
2If the skin is blistered or if there is a chance of eye infection, take the person to a doctor IMMEDIATELY.
Chemical Safety
• Do not use hydrogen or any other explosive gas with the ETC.
• Use of chlorine gas will damage the instrument.
• If you are using samples that may emit harmful gases, vent the gases by placing the instrument
near an exhaust.
Usage Instructions
Before connecting the rheometer to auxiliary equipment, you must ensure that you have read the relevant
installation information. Safety of the rheometer may be impaired if the instrument:
• Shows visible damage
• Fails to perform the intended measurements
• Has been badly stored
• Has been flooded with water
• Has been subjected to severe transport stresses.
