Page 9
- 9 -
2.2. Safety information
CAUTION!
The use of moisture analyzer MA 3Y regardless of both, safety
information and user manual guid elines ma y cause hea lth damage
and even death
WARNING:
Nominal voltage for a moisture analyzer is 230 VAC. It means
that safety usage precautions for low voltage devices must be
abide by while operating the device.
Three-core power supply cable with grounding pin comes
standard with a moisture analyzer.
If necessary, an extension cord can be used as long as it meets
the applicable standards and has a protective ground conductor.
Intended disconnection of the grounding cable is forbidden.
CAUTION:
Drying chamber cannot be opened during operation (drying
process). It is due to the fact that a halogen lamp and its glass
shield may reach the temperature of up to 400 C.
When setting up the moisture analyzer leave enough space to
prevent heat from building up and to keep your analyzer from
overheating. Leave about 20 cm around the instrument and
about 1 m above.
Air vents that are located in the housing cannot be covered,
sealed or blocked in any other way.
Do not put any flammable substances on, under or near the
moisture analyzer.
Be particularly careful when removing the sample from the
drying chamber: the sample itself, the drying chamber, shields
and the pan can still be extremely hot.
In case of any maintenance work (cleaning the inside of the
drying chamber), the moisture analyzer must be switched off.
Wait until all the components have cooled down. Do not perform
any modification to the heating module.
Same types of samples require taking particular safety
precautions.
They can pose a danger for people and objects. It is
always the user
who is liable for possible damages caused by the use of an
inappropriate sample.
CAUTION:
Page 10
- 10 -
Corrosion
Substances that release aggressive vapours (e.g. acids) during
the heating process. In this case, it is recommended to work
with
small samples. Otherwise, vapours can condense on cold
housing parts and cause corrosion.
WARNING:
Fire or explosion
Flammable or explosive substances, substances containing
solvents or releasing flammable or explosive gases or vapours.
Perform a risk analysis when in doubt relating to the sample
characteristics before carrying out the procedure.
For this type of samples apply the drying temperatures as low
as possible to prevent flames or explosion. During the analysis it
is
necessary to wear protective glasses and gloves. The samples
should be relatively small.
Under no circumstances can the instrument be left
Unsupervised!
WARNING:
Substances containing toxic and caustic or corrosive
components
Substances that release toxic gases or vapours can cause
irritations (eyes, skin or respiratory system), illnesses or even
death. Dry such substances only in fume hood.
Under no circumstances should the instrument be used in an area with
any
risk of explosion. The moisture analyzer is not designed to operate in
hazardous areas.
2.3. Intended use
A moisture analyzer MA 3Y series is designed to determine relative moisture
content in small samples of various substances, determine dry mass content
in small samples and determine mass of weighed objects.
MA 3Y ensures fast and precise determination process of water content in a
tested sample, and application of touch screen display considerably simplifies
operation and improves functionality of the moisture analyzer. A moisture
analyzer MA 3Y series can be used to determine humidity content of different
materials.
Page 11
- 11 -
At the initial stage of measurement, the device precisely determines the mass
of an object placed on instrument’s weighing pan. As the mass reading is
stabilized, the sample is quickly heated by a halogen lamp, an IR emitter or a
metal heater causing humidity evaporation from the tested sample. While
sampling, the moisture analyzer is continuously checking the loss of mass,
and on calculation, it displays current moisture content in a tested sample.
Compared to conventional methods of humidity content determination of
various substances, application of moisture analyzer MA 3Y series
considerably shortens measurement time and simplifies testing procedure. MA
3Y series allows for setting multiple parameters which influence the procedure
of moisture content determination in a sample, such as: temperature, time,
drying modes, etc.
2.4. Inappropriate use
CAUTION!
Do not open the drying chamber during drying process. Moisture analyzer
features a halogen lamp which is a very powerful heat source. Thus, user
should pay special attention no to touch those elements of a moisture
analyzer that get hot while drying procedure (i.e.: disposable pan, pan
handle, and inner shields of the drying chamber).
Remember that some of tested samples may become dangerous if heated
(appearance of poisoning vapours, danger of ignition or explosion).
Moisture analyzer MA 3Y series is not intended for dynamic weighing. Even if
small amounts of a sample are added to taken off the weighing pan, the mass
readout should only be taken only on stabilization of measurement result
(appearance of stability pictogram on the display).
Do not place any magnetic materials on the weighing pan, as this can cause
damage of the measuring system of the instrument. Be sure to avoid impact
shock and overloading the moisture analyzer in excess of the prescribed
maximum measuring range (max capacity), minus any possible tare weight
that has been applied).
Never use the moisture analyzer in an e nvironment endangered by an
explosion.
This moisture analyzer is not adjusted for operation in explosive areas. There
must not be any modification made to the moisture analyzer.
2.5. Principles of safety use
Moisture analyzer is in accord with all binding safety regulations. Nevertheless
there are exceptional circumstances that may cause danger.
It is forbidden to open an instrument housing. Inside there are no parts that
would require maintenance, repair or replacement carried out by a user. In

If the function is enabled, the following measurement results are
compared to each other in constant time intervals. If the results differ
less than declared AUTOZERO range, e.g. 1 division, the moisture
analyzer is automatically zeroed, and the markers of stable indication
and precise zero are displayed.
Active AUTOZERO means, that each measurement starts from the precise
zero point. There are, however, cases where the function may disturb the
measuring process, for instance during very slow load placing or pouring
onto the moisture analyzer’s weighing pan. In such case, the zero
indication correcting system may also correct the actual indication of a
load placed on the weighing pan.

16. WORKING MODES – general information
A moisture analyzer MA 3Y series in its standard version features the following
working modes:
Weighing
Means of operation: weight of a load is determined through an
indirect measurement. A moisture analyzer measures
gravitational acceleration force which attracts the load.
Obtained data is processed into a digital format and displayed
in a form of measurement result.
Drying
Means of operation: determining moisture content in a sample,
obtained by vaporization of all moisture components from a
sample placed inside a drying chamber of a moisture analyzer.
A measurement result is automatically calculated by the
software and visualized on an ongoing basis on moisture
analyzer’s display by comparing mass of a sample on
measurement start, in progress, and at the end of dying
process.

17. DRYING PROCESS – GENERAL INFORMATIO N
Working mode < Drying> is dedicated to determining moisture content in
a substance by its drying. On process start controlled by a user, the moisture
analyzer checks loss of mass of a substance placed in the drying chamber. The
substance sample is heated by a moisture analyzer, and on basis of mass
decrement, the software calculates moisture content in a sample, and visualizes
measurement result on the display. The drying result is continuously updated
during drying process course, and the process is completed automatically on
meeting finish mode requirements set by a user.
Page 66

SAMPLE PREPARATION FOR DRYING
This section of the MA 3Y user manual contains data on setting optimum test
results during drying processes. There are hints for selection of appropriate
drying parameters for various materials and substances.
17.1.1. Means of moisture content measurement on a moisture
analyzer
Measurement of moisture content in a tested sample is carried out by
determining loss of mass in a sample by its heating (humidity evaporation from
a sample).
RADWAG moisture analyzer MA 3Y series comprises two components: a
precision balance and a drying chamber. Compared to standard moisture content
determining methods, the measurements with application of RADWAG moisture
analyzer is much quicker and does not require additional mathematical
calculations (a result of moisture content is previewed on an ongoing basis
during product testing process).
Independently on moisture content determining method, the measurement
accuracy is highly influenced by means of sample preparation and selection of
testing parameters, such as:
• Sample size
• Sample type
• Drying temperature
• Drying time
In practice, the measurement accuracy is not as important as the speed of
obtaining measurement result (control over technological process). Thus,
heating a sample (with application of a halogen filament) carried out by a
moisture analyzer, makes the measurement process very time efficient and
short. Measurement speed can be additionally increased by appropriate adjusting
moisture analyzer’s parameters depending on tested substances.
Optimum temperature and drying time depend on sample type and size,
and anticipated measuring accuracy. Selection of drying parameters can
only be carried out on basis of test measurements.
17.1.2. Sampling and preparation
Sample features, its preparation and size are very important factors
influencing the speed and accuracy of measurement process.
Means of sampling and preparation are extremely important for repeatability
of measurement results, as a sample should be a representative part of tested
substance.
Page 67
- 67 -
Final measurement result is vastly conditioned by precise and considered
sample preparation. A sample used for analysis has to represent the total
structure of tested material. Sampling process should determine: sampling
means, sample disintegrating, particle size after disintegration, sample
uniformity and other. The sampling process should be carried out as quickly as
possible, so that a sample does not loose or absorb humidity from surrounding
area.
Applied sampling standards should match individual user needs and
requirements of tested material, its consistence and sample size.
Number of samples
Increasing number of tested samples also increases statistic measurement
certainty. Number of samples depends on uniformity of tested material, its
purity, accuracy of applied measuring method and anticipated accuracy of
obtained results.
Material mechanical disintegrating for measurements
Applied disintegrating method should be selected appropriately to tested
material. Substances that are hard and brittle (crisp) can be disintegrated by
cutting. Grinding such substances may cause their heating and thus humidity
vaporization, resulting in unreliable measurement results. Unless a substance
can be prepared for measurement otherwise than grinding, any possible
moisture content loss should be calculated.
Use of high-silica sand
Ensuring optimum substance drying requires that a sample has the largest
possible surface for moisture content vaporization. Test results of moisture
content in substance which surface has a form of a shell (e.g. glucose syrup) or
doughy (e.g. butter), can be much more reliable if a sample is mixed with a
dried high-silica sand (improvement of measurement accuracy and
repeatability).
Grease in a form of paste or melting substance s
Such substance requires testing with use of a filter made of glass fibre, which
considerably increases active evaporation surface by separating the substance
between the fibre. Initial filter drying is necessary only in case of measurements
which require very high accuracy.
Liquid substances
It refers to liquid substances, which by creation of drops on their surface,
caused by surface tension, may render difficulties in drying process. In such
cases, it is proved to use a glass fibre filter to shorten measurement time. The
filter causes separating tested liquid around the fibres, and increasing active
Page 68
- 68 -
evaporating surface. Initial filter drying is necessary only in case of
measurements which require very high accuracy.
Substances with structure of leather or temperature sensitive
In case of such substances it is proved to a glass fibre filter. While testing, a
substance is placed on a drying pan, and sample surface is covered with a filter,
which protects the sample from direct heat radiation. In such case, the sample is
heated by convection (which is milder than radiation).
Substances containing sugar
The surface of such substances often may
caramelize during testing procedure. Therefore, it is
recommended to use thin layer of a sample, and
moderate drying temperature.
17.1.3. Sample distribution on drying pan:
Loose materials
Dried in their natural state, i.e. in their natural
form or disintegrated. Sample disintegration causes
smaller dispersion between the following
measurements. Sample mass should not be too high,
and the sample should be evenly spread on whole
surface of the drying pan.
Liquid substances
Semi-fluid substances are dried in their natural
form. Large amount of grease (fat) occurring in
some of substances makes moisture content
determination difficult. In such case it is
recommended to use additional components, which
increase sample’s active surface and aid moisture
content releasing process from a sample. Such
components are high silica sand, blotting paper or
filter. Before drying a tested substance, initially dry
the additional component, so that its humidity is
close to zero.
Solid objects
Depending on solid object’s structure (dense or loose), moisture content
determining process may take short or long time. The size of solid’s surface
determines the speed of drying process, and measurement reliability. Thus, the
surface of a solid object should be as large as possible. Since solid objects
release moisture through their outer surface, sample thickness is another
important factor.
Page 69
- 69 -
17.2. SELECTION OF DRYING PARAMETERS
17.2.1. Selecting optimum sample mass
Sample mass influences the accuracy of measurement result and
measurement time. Higher mass of a sample, causes higher amount of water
(moisture content) which needs to evaporate, and therefore measurement
time is also longer.
Obtaining short measurement time is feasible in case of small sample mass,
but sample mass cannot be too small, as it may negatively influence required
measurement accuracy.
17.2.2. Influence of sample mass on measurement result repeatability
Sample mass considerably influences repeatability of measurement results
obtained on a moisture analyzer. Relation between sample mass and
repeatability is presented below.
Sample mass
Repeatability
to 2g
±0,24%
to 10g
±0,06%
Over 10g
±
0,04%
The above data refers to a model, uniform sample, containing no moisture due
to the evaporation process and showing no signs of decomposition (e.g. wet
high-silica sand).
The results uncertainty cannot be avoided, this is due to sample nature and
moisture analyzer repeatability. In practice, it means that obtained
measurement result may exceed repeatability values provided above.
17.2.3. Drying temperature
Drying temperature has the largest impact on drying time. Temperature value
depends on type of dried substance. Too low drying temperature causes too
Page 70
- 70 -
low moisture content evaporation (under-dried sample), and consequently
unnecessary extending of measurement time. Too high drying temperature
causes burning of dried sample
(sample overheating, chemical
decomposition). Drying temperature
of traditional method (using a
furnace) is specified in applicable
industry or company standards.
Unless standards apply, then
temperature should be adjusted by
tests.
On selecting drying temperature value, proceed as follows:
• Determine moisture content in a sample
• Determine temperature of substance chemical decomposition by tests
• Compare result obtained on a moisture analyzer with the one of
traditional method
When drying a sample with high moisture content, it is possible to shorten
measurement time by selecting “quick” drying mode. In such case, the
majority of moisture content is released drying temperature higher than set.
Only after some time, the temperature is lowered to the set value, and
maintained until completing drying process.
17.2.4. Selecting drying mode
The software of moisture analyzer MA 3Y series
enables selecting one of four drying modes:
• Standard
• Quick
• Mild
• Step
STANDARD mode
Standard mode is the most frequently used of all
drying modes. It enables accurate determining of
moisture content is a dried sample.
MILD mode
Mild mode is used in case of drying substances that are sensitive to rapid heat
emitted by filaments operating at full power in the initial stage of drying
process. This mode prevents from decomposing of substances sensitive to
heat by mild temperature increase in set amount of time (time interval has to
Page 71
- 71 -
be selected by tests). Mild mode is recommended to drying samples of leather
structure.
QUICK mode
Quick mode is recommended to drying samples
that moisture content varies from 5%, and 15%.
In the initial stage of Quick mode, heating takes
place at full power of the filaments, causing
heating the drying chamber to increased
temperature (maximum temperature value is
higher by 30 % from set drying temperature). Overheating compensates heat
loss during evaporation of large moisture content in the test’s initial stage.
STEP mode
Enables determining up to three steps with
random drying temperature. Step mode is
recommended for drying substances with
moisture content over 15%. Temperature and
heating time in each step have to be adjusted
by tests.
17.2.5. Drying time
Drying time is set by selecting one of available finish mode criteria. This
means that a moisture analyzer must meet pre-set criterion (one of the
requirements: mass over time, time) to automatically finish the drying mode.
Finish of drying process can be triggered by amount of time, independently on
loss in mass. This criterion is used for substances that may decompose during
drying process, and their mass does not reach constant value.
The second criterion is loss in mass (less than 1 mg) in defined amount of
time.
Automatic finish mode (Auto switch off mode)
MA 3Y operator can choose between various types of finish modes:
- Automatic 1 (change 1mg/10s)
- Automatic 2 (change 1mg/25s)
- Automatic 3 (change 1mg/60s)
- Automatic 4 (change 1mg/90s)
- Automatic 5 (change 1mg/120s)
- Time defined (maximum drying time 99 hours 59 minutes)
- Manual (on pressing a function key)
- User defined 1 (set mass change ratio ∆m 0,1-9,9mg and time interval ∆t
max 2,55 sec.

After entering the moisture analyzer settings, the user can define all drying
parameters, and main data for printing completed measurements (data type,
time interval between printing the following measuring data). The data is
definable in one menu window.
Procedure:
1. Press grey coloured workspace
2. Moisture analyzer’s display indicates menu: Settings, Keys, Information,
Printouts, Profile,
3. Press <Settings> key,
4. The display indicates functions related to drying mode, such as:
− Drying mode [means of heating a sample]
− Finish mode [criteria on finishing drying process]
− Result [moisture content measuring unit, active on drying process
start]
− Printout interva l [time intervals in which measurement data is printed]
− Start mass control [enabled / disabled – meeting a requirement of
determined start mass of a sample, with declared tolerance of this mass
value (setting mass value and its tolerance is carried out in database of
products)]
− Print measurements [printing indirect measurement result of moisture
content determining process, with time interval set in parameter
<Measurement time >]
Means of setting each parameter is the same as in case of the previous
menu option. The only difference refers to possibility of declaring parameter
of controlling start mass for a sample.
This parameter determines use of a sample with specific mass to test its
moisture content.
CONTROL OF START MASS enables setting one of three options:
No – option disabled, mass of a sample prepared for drying is not controlled
by the software
Optional – option enabled, the display shows a bar graph demonstrating
graphic visualization of sample mass in relation to mass value saved in the
database of products. It is a sample mass and its tolerance limits set in the
software.
Before applying this option, add a product in the database, including data on
sample mass and its checkweighing limits.
On enabling this option, the moisture analyzer’s software displays
commands on placing a sample with determined mass on the drying pan.
However, if a user decides otherwise, then a moisture analyzer starts drying
process even if sample mass exceeds determined threshold limits for a
tested sample mass.
Page 80
- 80 -
Mandatory - option enabled, the display shows a bar graph demonstrating
graphic visualization of sample mass in relation to mass value saved in the
database of products. It is a sample mass and its tolerance limits set in the
software.
Before applying this option, add a product in the database, including data on
sample mass and its checkweighing limits.
On enabling this option, the moisture analyzer’s software displays
commands on placing a sample with determined mass on the drying pan.
Unless the sample mass is within set threshold limits, the software does not
allow to start drying process.
There are two ways of using this option:
1. For an optional product, using quick access keys:
< Checkweighing thresholds> or < Target value>.
2. In combination with a specific product saved in the < Database of
products>.
In the 1st case, the target value, checkweighing thresholds and percent
tolerance of mass should be set using quick access keys.
In the 2nd case, the value of mass, and tolerance fields have to be specified
their corresponding fields of the <Database of products>.
SETTING TOLERANCE LIMITS FOR SAMPLE MASS:
MIN and MAX THRESHOLDS: the software accpets sample mass as
correct, if it is within set value of MIN and MAX thresholds (MIN and MAX
criteria are set in the database of products).
TOLERANCE: the software accpets sample mass as correct, if it is within
set percent tolerance limits of total sample mass (±%) - (data set in the
database of products).
Before starting drying process, a user should declare parameters of a
sample which is loaded on the drying pan: MIN and MAX, target mass and
percent tolerance of sample mass. On setting above criteria the software
allows for beginning the drying process.
1. Defining the value of Min/Max thresholds is carried out in the Database of
Products during editing a Product or by using quick access key <
Checkweighing thresholds >.
Procedure:
• Press grey coloured workspace, and then <Keys> option
Page 81
- 81 -
• Assign <Checkweighing thresholds> option to one of the quick access
keys displayed in the bottom bar
• Return to drying mode
• Press < Checkweighing thresholds> soft key and insert the value of
Low Threshold and High Threshold. Return to drying mode.
• After displaying <PREPARE SAMPLE> command, the display, below the
measurement result, indicates a bar graph, which using colours shows
current mass on the drying pan.
• Yellow colour – current mass below set Low Threshold value
• Green colour – current mass within set thresholds values
• Red colour – current mass above set value of High Threshold
2. Defining the value of target mass is carried out using a quick access key
< Target mass >
Procedure
• Press grey coloured workspace, and then <Keys> option
• Assign <Target value> option to one of the quick access keys displayed
in the bottom bar
• Return to drying mode
• Press < Target value> soft key and insert mass to be obtained in
measuring process,
• Then, insert +/- percent tolerance of the target mass, (accessible range
0 – 100%)
• The display, below the measurement result, indicates a bar graph
which contains:
o Current mass (visualized with colours)
o Target Mass value (visualized with black marker)
Page 82
- 82 -
Caution:
The checkweighing thresholds and target mass options may function
simultaneously during drying process. In such case, the tolerance field is
realized by Min and Max thresholds, and the bar graph indicates target mass
marker.
On entering the database and selecting a product, which has the target
mass value and Min & Max thresholds assigned, the software, while
controlling the start mass, will first consider the Min and Max thresholds.
The values of Min and Max thresholds can be changes before drying process
using quick access keys displayed in the bottom bar.
New values are accepted are instantaneous, and they are not saved in the
product record in a corresponding database.
