Class A Warning
Warning: This is a class A product.
In a domestic environment this
product may cause radio interference in which case the user may
be required to take adequate
measures.
4
!
Make sure before getting started
that the voltage rating printed on
the manufacturer‘s label is identical
to your local line voltage (see the
section on “Connecting the Moisture Analyzer to AC Power” in the
chapter entitled “Getting Started”)
– The analyzer comes with a power
supply that has a grounding conductor
– The only way to switch the power
off completely is to unplug the
power cord.
– Position the power cable so that it
cannot touch any hot areas of the
moisture analyzer.
– Use only extension cords that meet
the applicable standards and have
a protective grounding conductor.
– Disconnecting the ground conduc-
tor is prohibited.
– Connect only Sartorius accessories
and options, as these are optimally
designed for use with your moisture analyzer.
– Protect the moisture analyzer from
contact with liquid.
– If there is visible damage to the
moisture analyzer or power cord:
unplug the equipment and lock it
in a secure place to ensure that it
cannot be used for the time being.
!
Clean your moisture analyzer
according to the cleaning instructions only (see “Cleaning”).
Do not open the analyzer housing.
If the seal is broken, this will result in
forfeiture of all claims under the manufacturer’s warranty.
In case you have any problems with
your moisture analyzer:
$ contact your local Sartorius office,
dealer or service center
Warning: Severe Burns!
– When setting up the moisture analyzer,
leave enough space to prevent heat
from building up and to keep your
analyzer from overheating:
– leave 20 cm (about 8 inches) around
the moisture analyzer
– 1 m (3 ft.) above the device
– Do not put any flammable substances
on, under or near the moisture analyzer,
because the area around the heating
unit will heat up.
– Be careful when removing the sample
from the chamber: the sample itself, the
heater module and the sample pan used
can still be extremely hot.
– Do not remove the heater module unit
during operation: the heating element
and its protective glass panels can get
extremely hot!
– Prevent excess heat build-up around the
analyzer.
5
Hazards for persons or equipment
posed by using specific samples:
Fire Explosion
– Flammable or explosive substances
– Substances that contain solvents
– Substances that release flammable or
explosive gases or vapors during the
drying process
In some cases, it is possible to operate
the moisture analyzer in an enclosed
nitrogen atmosphere to prevent the
vapor released during drying from
coming in contact with oxygen in the
surrounding atmosphere. Check on a
case-to-case basis whether this method
can be used, because installation of the
analyzer in too small an enclosed space
can affect its functions (for instance
through excessive heat build-up within
the analyzer). When in doubt, perform
a risk analysis.
The user shall be liable and responsible
for any damage that arises in connection with this moisture analyzer.
Poisoning Caustic burns
– Substances containing toxic or caustic
or corrosive substances: These may
be dried only under a fume hood.
The value for the “lower toxic limit” in
a work area must not be exceeded.
Corrosion:
– Substances that release aggressive
vapors during the heating process
(such as acids): In this case we recommend that you work with small sample
quantities. Otherwise, vapors can condense on cold housing parts and cause
corrosion.
The user shall be liable and responsible
for any damage that arises in connection with this moisture analyzer.
– Sample Pans (Delivered with the
Analyzer):
The reusable metal pans are not
made of stainless steel. For this reason,
they are not resistant to corrosion.
These pans can be used only for powder
and granules (e.g. plastics) with very
low moisture content.
If the moisture content is higher, the
disposable aluminium pans (90 mm
diameter) must be used (see chapter
“Accessories”).
6
Caution
Do not touch the metal surfaces inside
the drying chamber while removing
or placing a sample in the analyzer since
the surfaces are very hot.
Do not touch the heater hood ventilation area at any time because this area
can be hot during and after a test.
§ Do not test flammable or toxic
materials.
§ Use the analyzer in a fume hood if the
samples emit fumes which could be
harmful.
§ Know where the fire extinguisher is
located. Use only an extinguisher rated
for use with electrical fires.
§ Keep the analyzer clean. Always unplug
the analyzer and cool it thoroughly
before cleaning or performing service.
§ Do not block the ventilation areas of
the heating chamber.
§ If necessary, press the Start|Stop key
during a test to stop the test.
§ Locate the analyzer away from
flammable materials.
§ If liquid is spilled into the analyzer,
unplug the Heating Module from the
electrical supply immediately.

The Mark 3 LTE Moisture Analyzer is designed to
test moisture content in a large variety of materials
including powders, pastes and liquids. The performance of the analyzer is dependent upon selecting
optimum drying analysis conditions for your specific
sample type. Sartorius will support you in finding
the set of testing parameters (referred to as a program) you need for your specific tests. On request,
we will provide a chart of the parameters and test
results we have compiled by testing samples in our
laboratory and comparing the results to those
obtained by reference methods.
If our chart of applications shows a drying program
that is not already programmed into your analyzer,
you may do this yourself by following the instructions under Setup in this manual.
Standby Screen
During warm-up, your analyzer will enter the Standby mode and the Standby screen will be displayed.

!
with a New Program
When creating a new program, the standby
temperature setting from the previous drying
program is used automatically by the analyzer.
Example:
You have created a new program for drying
a temperature-sensitive sample at low temperature. The analyzer uses the standby temperature, e.g. 165°C, from the previous program.
You must call up the standby temperature
parameter and change the temperature value.
If you forget performing this setting, your analyzer is always too hot before starting the test.
22
Default Drying Program
Your analyzer is delivered with a default drying program. The drying program contains all the specific
parameters to test a sample including temperature,
endpoint, unit of measure, standby temperature,
etc. You will notice if you are in the default program
or a specific material program by the program name
at the top left of the display.
23
Program name: Default
Temp1=105C

4. At the “Add sample to pan” prompt, open the heater
hood and begin adding sample to the pan. A bar
graph on the display will guide the operator to place
the correct amount of sample as set by the ideal
weight parameter of the drying program. Continue
adding sample until the beeper sounds, indicating
that the sample amount is within 10% of the ideal
weight. The exact weight is also displayed on the
screen.
5. At the “Close heater hood” prompt, close the heater
hood. The balance will capture the initial weight of
the sample “Sampling” and then show that the test
is in progress. The display will change to show current information including the elapsed time and the
current percentage weight loss in the units as specified in the drying program.
