RADWAG MA 200.3Y Moisture Analyzer - Manual (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 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
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
