…
Thank you for purchasing a Halogen Moisture Analyzer from METTLER TOLEDO.
Your Moisture Analyzer is fast and reliable. It offers a high level of operating convenience and useful functions
to facilitate determination of the moisture content of your samples.
Behind your instrument stands METTLER TOLEDO, a leading manufacturer of not only balances and scales for
the lab and production, but also analytical measuring instruments. A customer service network covering the
entire globe with well trained personnel is your service at all times, whether you are choosing accessories or
require guidance for a specific application to ensure optimum utilization of your instrument.
Your Halogen Moisture Analyzer is used for determining the moisture content of almost any substance. The
instrument works on the thermogravimetric principle. At the start of the measurement the Moisture Analyzer
determines the weight of the sample, the sample is then quickly heated by the integral halogen heating module
and the moisture vaporizes. During the drying process the instrument continually measures the weight of the
sample and displays the reduction in moisture. Once drying has been completed, the moisture or solids content
of your sample is displayed as the final result.
Of decisive importance in practice is the rate of heating and even heating of the surface of the sample. In com
parison with conventional infrared heating or the drying oven method, for example, the halogen heating module
of your instrument needs a shorter time to reach its maximum heating power. It also allows use of high temper
atures, an additional factor in shortening the drying time. Uniform heating of the sample material ensures good
repeatability of the drying results and makes it possible to use a smaller amount of sample.
The Moisture Analyzer conforms with all common standards and directives. It supports stipulations, work tech
niques and result records as demanded by all international quality assurance systems, e.g. GLP (Good Labora
tory Practice), GMP (Good Manufacturing Practice). The instrument has a CE declaration of conformity and
METTLER TOLEDO as the manufacturer has been awarded ISO 9001 and ISO 14001 certification. This provides
you with the assurance that your capital investment is protected in the long term by a high product quality and
a comprehensive service package (repairs, maintenance, servicing, adjustment service).

ing instructions for further reference.
Never make any modifications or constructional alterations to the instrument and use only original spare parts
and optional equipment from METTLER TOLEDO.
Protective Clothing
It is advisable to wear protective clothing in the laboratory when working with the instrument.
A lab coat should be worn.
A suitable eye protection such as goggles should be worn.
Use appropriate gloves when handling chemicals or hazardous substances, checking their
integrity before use.
Safety Notes
WARNING
Risk of electric shock
Your instrument is supplied with a 3-pin power cable with an equipment grounding conduc
tor. Only extension cables which meet this relevant standards and also have an equipment
grounding conductor may be used. Intentional disconnection of the equipment grounding
conductor is prohibited.
CAUTION
The Halogen Moisture Analyzer works with heat!
a) Ensure sufficient free space around the instrument to avoid heat accumulation and over
heating (approx. 1 m free space above the heating module).
b) The vent over the sample must never be covered, plugged, taped over or tampered with
in any other way.
c) Do not place any combustible materials on, under or next to the instrument since the
area around the heating module may be hot.
d) Exercise caution when removing the sample. The sample itself, the sample chamber, the
draft shield and any sample vessels used may still be very hot.
e) During operation, you should never open the heating module itself as the ring-shaped
heating reflector or its protective glass can reach 400 °C! If you have to open the heating
module e.g. for maintenance, disconnect the instrument from the power supply and wait
until the heating module has cooled down completely.
f) No modifications must be made within the heating module. It is particularly dangerous to
bend any components or remove them or to make any other changes.
9Safety Information

4.6Leveling Drying Unit
Exact horizontal positioning and stable installation are prerequisites for repeatable and accurate results. To
compensate for small irregularities or inclinations (±2%) at the location, the instrument must be leveled.
For exact horizontal positioning, the drying unit has a level indicator
(level) and 2 leveling screws. When the air bubble in the level indica
tor is exactly in the center, the instrument is standing perfectly horizon
tally. To level it, proceed as follows:
1 Position your Moisture Analyzer at the selected location.
2 Turn the two leveling feet until the air bubble is in the center of the
level indicator.
L = left foot
R = right foot
Air bubble at "12 o'clock" turn both feet clockwise
Air bubble at "3 o'clock" turn left foot clockwise,
right foot counterclock
wise
Air bubble at "6 o'clock" turn both feet counter
clockwise
Air bubble at "9 o'clock" turn left foot counterclock
wise, right foot clockwise
Note
The drying unit should be re-leveled each time its location is changed.

7.1Adjustments
Navigation: Home > Test/Adjust > Adjustments
In this menu item you can adjust the balance as well as the heating module of your instrument. For relevant
settings see Test / Adjustment settings (page42).
Attention
●
To obtain accurate results, the balance must be adjusted at the point of use under measuring condition in
order to match the gravitational acceleration at its location. The instrument must be connected to the power
supply for approximately 60 minutes in order to reach operating temperature before adjusting. Adjusting is
necessary:
•
before the instrument is used for the first time.
•
after a change of location.
●
We advice you to wait at least 30 minutes after a drying operation (or previous heating module adjustment)
before performing the adjustment.
Fully automatic adjustment FACT
This instrument is equipped with fully automatic adjustment with two internal weights called Fully Automatic
Calibration Technology (FACT).
The balance adjusts itself automatically:
●
after the warm-up phase after connection to the power supply.
●
when a change in the ambient conditions (temperature) could lead to a noticeable deviation in the mea
surement.
●
on a fixed time interval
FACT is activated by default and can be switched off as required e.g. when performing an external adjustment,
see FACT (Fully automatic adjustment) (page45).

8Method Definition
Navigation: Home > Method definition
What is a method?
Methods simplify and accelerate your daily work. A method contains all settings for measuring the moisture
content of a particular sample (substance). It can be recalled by tapping a measurement button or a shortcut
and your instrument immediately operates with the corresponding settings.
The optimal setting of parameters and the drying time depends on the type and size of the sample and the
desired accuracy of the measurement result. The exact parameters can only be determined experimentally, see
How to Obtain Best Results (page109). Your Instrument helps you to determine the settings.
Method definition
This function offers you to define new methods and to change, delete, export or import existing methods
depending on the user rights. It allows you to store up to 300 individual methods.
All parameters using in a drying method, can be defined under this menu item.
Note
●
In most cases it is sufficient to set Main measurement parameters.
●
You will find more information about defining methods in the delivered application brochure «Guide to Mois
ture Analysis» or see How to Obtain Best Results (page109).

8.1.1.4Settings of Step drying
Step drying
This drying program is suitable for the drying of substances composed of several compo
nents which vaporize at different temperatures (e.g. ethereal oils). With this program drying
is performed stepwise, i.e. the sample is preheated to a particular temperature (1st step)
and kept at this temperature for the selected switch-off criterion e.g. time or weight loss per
unit of time. The temperature can be increased for the next step, lowered or remain the
same. At the last step, the switch-off criterion terminates the measurement. Maximum 5
steps are selectable.
Step drying can also be used for faster determining of samples with high moisture content.
In this case the first step should be set with a higher temperature than for the last step. This
reduces evaporation.
Tip for the measurement of plastic granules:
Setting of switch-off criterion "timed" for the first step (possibly same temperature setting as
for step 2). The larger sample (e.g. 30 g) has to be heated first before it gives off the small
amount of moisture. This prevents that the measurement is terminated prematurely. Setting
of switch-off criterion "5" for the second step which terminates the measurement automati
cally.

This function offers you different switch-off criteria. A switch-off criterion defines when the instrument should end
the drying or should start the next step ("Step drying"). Switch-off criteria ensure that measurements are finished
in the same condition (weight loss per time) every time, ensuring repeatable measurements.

8.1.3Settings of Start Weight
Navigation: Home > Method Definition > Method name > Main measurement parameters > Start weight
The start weight affects both the duration of the measurement as well as the accuracy of the results. A small
weight results in a shorter duration of the measurement but will decrease the accuracy of the result. With this
function you can define a start weight so that the samples are approximately of equal weight thus improving the
repeatability of the measurements. The weighing-in aid assists you in weighing-in the sample. At most of the
samples the target weight is in the range of 2–5g (plastics 30g). We recommend to cover the whole surface
of the sample pan with a thin uniform layer of sample.

ten times higher (0.1mg weight / 0.001% moisture). The high resolution is especially suitable for samples
with low moisture content (lower than 1%). Careful sample preparation is extremely important for these kind of
samples!

Manual
We advise you to use the manual operating mode for samples which contain readily volatile substances. In
contrast to the automatic operating mode, in the manual operating mode the sample chamber does not auto
matically close when the [Start drying] button is tapped. However, the initial weight (wet weight) important for
the determination of the moisture content is recorded. In the manual operating mode you have time for further
preparation of the sample (e.g. mixing with quartz sand or even distribution of the sample) while weight losses
due to evaporation during the preparation time are measured from the outset. As soon as the sample is ready
for drying, press [ ] key. The automatic sample chamber closes and drying starts. In the manual operating
mode you can open the sample chamber during a drying operation. In contrast to the automatic mode, drying
will not be stopped but simply interrupted until the automatic sample chamber is closed again.

Test a method
This function allows you to test the settings during the definition phase of a method. Testing is possible at any
time. Test measurements are recorded in the journal and marked as test results. If you wish to work with the
switch-off criterion «weight loss per unit of time» and are not familiar with the behavior of the sample, the test
measurement will help you select the suitable setting. For more information about switch-off criteria, see Set
tings of Switch-off Criterion (SOC) (page70).
The diagram illustrates the progress of a
drying. The points at which the individual
switch-off criteria were reached (1-5) are
marked.
During this measurement, the measured values are recorded the switch-off criteria 1 to 5 and maybe one of a
free-defined switch-off criterion. The measurement terminates after the defined time (default 30minutes). Note
that the start weight affects the switch-off criterion. The test time can also be switched off. In this case the mea
surement terminates after reaching the predefined switch-off criterion. Nevertheless, all switch-off criteria are
recorded.
By comparing the measured values with values of a reference method e.g. drying oven and the standard devia
tion, you can define the appropriate parameter settings. For more information see the application brochure
«Guide to Moisture Analysis».
Carry out all measurements under Home > Method Definition > Method name > Tests before releasing a
method. The results of test measurements are specifically marked.
Attention
Before releasing the method, check if the determined switch-off criterion is set.

Already sampled data are stored and an entry will be made in the results. The result is marked as aborted.
Adding a comment
At the end of a measurement you can add a comment to the result of the measurement. This comment is stored
in the measurement result and can be printed. A comment can only be entered before leaving the current mea
surement.
1 To create a comment, tap [Note].
The keyboard dialog appears.
2 Enter a comment.
3 Confirm with [OK].
9.2Work with Weighing-in Aid
The weighing-in aid can be defined for each method and facilitates weighing in of the sample to a target value.
This is particularly necessary if you require all the samples of a method you wish to process to have same
weight in order to improve the repeatability of the measurement results. In addition, the weighing-in aid can be
set as active so that the drying process cannot be started if the weight of sample is outside the set tolerance.
You are therefore compelled to weigh-in the correct quantity of sample. If all sample weighed are within toler
ances then this will improve the repeatability. The weighing-in aid is available only if start weight has been acti
vated. For further information see Settings of Start Weight (page74).

In such cases, contact your METTLER TOLEDO representative.
11.1Cleaning
To obtain precise measurement results, we recommend you to clean the temperature sensor and the protective
glass of the halogen lamp regularly. Please note the following directions for cleaning your instrument.
WARNING
Risk of electric shock
The instrument must be disconnected from the power supply, before cleaning or other main
tenance work to be performed.
CAUTION
Danger of burns
The interior parts of the heating module as well as the parts in the sample chamber could be
very hot.
– Wait until the heating module has cooled down completely.
General
Your Moisture Analyzer is made from high quality, resistant materials and can therefore be cleaned with a com
mercially available, mild cleaning agent e.g. isopropanol.
Attention
●
Use a lint-free cloth for cleaning.
●
Ensure that no liquids enters the interior of the instrument.
●
Heating Module
Clean the exterior of the heating module with a mild cleaning agent although the housing is extremely
rugged and resistant to solvents.
●
Terminal
On no account use cleaning agents, which contain solvents or abrasive ingredients, as this can result in
damage to the terminal overlay.
●
Never open the housing of the instrument – they contain no components, which can be cleaned, repaired or
replaced by the user.
Note
After the temperature sensor or the protective glass have been cleaned, we recommend adjusting the heating
module using the temperature adjustment kit, see Temperature Adjustment (page57).

●
Support on which the instrument is standing is not sufficiently stable. Use
a stable support.
●
Surroundings are very unstable (e.g. vibrations, air draft, humidity). Pro
vide better environmental conditions.
●
Sample has more or less moisture between sampling and starting the
drying process.
●
Sample is not evenly dispersed on the pan.
●
Start weight has not always the same value.
●
Samples are not homogeneous, i.e. they have different compositions.
The more inhomogeneous a sample, the larger the amount of sample
needed to obtain a repeatable result.
●
Selected drying time is too short for the "Timed switch-off" criterion.
Extend the drying time or select a suitable switch-off criterion "Weight
loss per unit of time".
●
Sample does not become completely dry (e.g. awing to skin formation).
Dry the sample with the aid of glass fiber discs.
●
Selected temperature is too high and the sample has oxidized or decom
posed. Lower the drying temperature.
●
Sample boils and the splashed drops continuously change the weight.
Lower the drying temperature.
●
Granulation is not homogeneous or too large.
