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.
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
10
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 environment 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

6. START-UP
On plugging to mains the moisture analyzer carries out a display test (all
pictograms and digits appear on the display). Then the display shows software
name and number, and enters weighing mode.
6.1. Moisture analyzer temperature stabilization period
Before start of measuring processes, it is necessary to wait until the moisture
analyzer is thermally stabilized. It is a period of so called moisture analyzer’s
self-heating.
For moisture analyzer MAC series which before plugging to mains was stored
in room temperature, self-heating period takes approximately 30 minutes. For
moisture analyzers that were stored in much lower temperatures before
plugging to mains (e.g. during winter period) thermal stabilization should last
approximately 4 hours.
During self-heating period the indications on moisture analyzer’s display may
change. Correct operation of a moisture analyzer is possible within
temperature range specified in the technical parameters, see point 1.
It is recommended that ambient temperature changes at moisture analyzer’s
place of use are very small (slow).
