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

Moisture analyzer is in accord with all binding safety regulations. Nevertheless
there are exceptional circumstances that may cause danger.

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).

8. WEIGHING

Before start of measuring process or in case of essential change of ambient
conditions at a workstation (e.g. ambient temperature change at a workstation)
the moisture analyzer requires adjusting. The procedure of moisture analyzer
adjustment is described further in this user manual.

• Before start of measuring procedure, it is recommended to load the
moisture analyzer’s pan a few times with mass close to the max
capacity,

• Check if unloaded moisture analyzer indicates “precise zero” -
and whether measurement is stable -

, if not press ESC/TARE

key,

• Place weighed object on moisture analyzer’s weighing pan and read
result only on stabilization of measurement result,

• Mass indication of a load placed on moisture analyzer’s weighing pan
can be tarred for multiple times by pressing ESC/TARE key (pay
attention not to exceed maximal capacity of a moisture analyzer by
applying multiple tare function).

During times between carrying out the following measurement series do not
unplug the moisture analyzer from mains. It is recommended to switch off
moisture analyzer’s display by pressing ON/OFF key. On repeated pressing of
the ON/OFF key the moisture analyzer is ready for operation and carrying out
the following measurements.

9. MOISTURE ANALYZER MAIN PARAMETERS. ADJUSTING MOISTURE ANALYZER OPERATION TO AMBIENT CONDITIONS AT A WORKSTATION

• Setting filtering level – AuE.

• Autozero function – Auto.

• Access to library of drying modes – Libr.

• Backlight of measurement result - bl.

• Display brightness - blbA

• “Beep” sound – reaction on pressing a key – bEEP.

23

User of a moisture analyzer can adjust its operation to current ambient
conditions at a workstation (by changing the value of digital filters), or
according to user needs (autozero operation or display backlight) by using
parameters grouped in this function.

9.1. Setting filtering level

- use navigating keys to select desired filter value,

AuE = StAnd - (normal) – normal operation conditions,
AuE = Slouu - (slow) – harsh operation conditions – vibrations, etc.,
AuE = Fast - (fast) – good operation conditions – no vibrations, etc.

24

CAUTION:

The stronger filtering setting the longer weighing time.

9.2. Autozero function

In order to ensure moisture analyzer’s precise mass indication, autozero (Auto)
software parameter has been introduced. The application of this function is
automatic control and correction of zero indication. When function is enabled,
it compares moisture analyzer indications at declared time interval e.g. 1 s, on
conditions that weighing pan is unloaded and display indication is close to zero.
If results vary less than declared AUTOZERO range e.g. one division, the
moisture analyzer will zero automatically, display marker of stable

measurement result

and precise zero marker .
If AUTOZERO function is enabled, then each weighing process starts from
precise zero point. There are, however, some cases when this function can be
a disturbing factor of measuring process; for instance very slow placing of load
on the weighing pan (e.g. load pouring) – in such case system of zero
indication correction can also correct actual indication of loaded mass.

Auto = On - autozero enabled,
Auto = OFF - autozero disabled.

25

9.3. Access to library of drying programs

In order to use the library of drying programs set parameter <Libr> to value
<YES>:

no - libraries of drying programs disabled,
YES - libraries of drying programs enabled.

26

9.4. Backlight of measurement result (display backlight)

The function enables switching on and off backlight of measurement result on
the display.

OFF - backlight disabled
On - backlight enabled
Aut - backlight disabled automatically if measured indication does not

change within 10 seconds.

CAUTION

Moisture analyzer software has implemented option of automatic
backlight switch off bl = Aut. In case of this setting, the backlight is
switched automatically off if measurement results does not change
within 10 seconds. Backlight is automatically activated at the moment of
weighing result change on moisture analyzer’s display.

27

9.5. Brightness adjustment of display backlight

bEEP = OFF - signal of pressing function key disabled.

28

10. MOISTURE ANALYZER ADJUSTMENT

As the gravitational acceleration force has different value at various latitudes
and altitudes, a moisture analyzer should be adjusted to present working
conditions. This process should take place at the first installation of the
instrument on site and at its every re-location – as in case of ambient
temperature changes.
In order to ensure the highest weighing accuracy, it is recommended to
periodically refresh moisture analyzer’s accuracy by carrying out adjustment
process.

Adjustment should be carried out:

- Before the beginning of measuring process,

- If long breaks between following measuring series occur.

Types of adjustment:

- adjustment with an external weight

Remember to carry out adjustment process only when there is no load on
the weighing pan! In case there is load on the weighing pan, the display will
indicate a command Er1 Hi. It is a command of unloading the pan.

Adjustment process can be aborted if necessary by pressing Esc key!

29

10.1. External adjustment

External adjustment in moisture analyzer MAC series should be carried out
with an external mass standard / weight class F2 or higher.

Start of external adjustment process,

On selecting CAL mode, the moisture analyzer displays a command unLoAd –

Step 2.

Step 3.

Insert parts of the set into the
drying chamber:

• shield and
thermometer

After set assembly close the
drying chamber and start
temperature adjustment.

CUTION: Use most gentle movements so as not to damage moisture
analyzer’s mechanism.

33

Go to menu P1-03 tE_CAL, adjustment process is initiated automatically.
The moisture analyzer displays current temperature in the drying chamber.
After 8 minutes the display indicates (pulsating) temperature value. Use
navigating keys (up and down arrow) on moisture analyzer’s overlay to set
temperature value to be equal to the current temperature displayed on the
control thermometer. Use Print/Enter key to start part two of temperature
adjustment process. The moisture analyzer switches on the halogen lamp and
heats the drying chamber to a defined temperature value. The temperature
value is maintained for 8 minutes, and its value is visible on moisture analyzer’s
display. After 8 minutes the display indicates (pulsating) temperature value.
Use navigating keys (up and down arrow) to set temperature value to be equal

34

to the current temperature displayed on the control thermometer – as in
previous step. On entering the temperature value and accepting it by pressing
Print/Enter key, the software starts the last part of temperature adjustment
process. The moisture analyzer heats the drying chamber to another
temperature value, which is maintained for 8 minutes. Current temperature of
the dying chamber is visible on the display. After 8 minutes the display
indicates pulsating temperature value, which should be changed to be equal to
the one indicated on control thermometer (as in previous steps). On entering
temperature value accept it by pressing Print/Enter key. Temperature
adjustment process is completed, and the display indicates name of the
parameter: P1-03 tE_CAL.

In case of moisture analyzer with maximum heating temperature 250 °C, the
temperature adjustment process is the same, with only difference in higher
temperature values in each part of the process.

Return to weighing mode

(see point 7.2 – return to weighing mode).

10.4. Adjustment report printout

On completing an adjustment process, the moisture analyzer enables
generating a report from adjustment process. The report can be printed on a
connected printer and sent to a computer and saved in a form of file for future
records.

YES - report is printed.
no - report is not printed

35

Remember, that if the parameter is set to YES, then a report is generated and
sent (printed) automatically.

15. DRYING PROCESS WITH USE OF DRYING PROGRAM LIBRARY

In order to start drying process with use of drying program library, the user has to
enable access to the libraries in moisture analyzer’s menu: parameter – P6-01 Libr

has to be attributed <YES> (see point 9.3. of this user manual). The moisture

analyzer MAC series can comprise up to 20 drying procedures / programs, which
are optionally configured, saved and used by selecting one of them.

Should one of drying procedures / programs be used, follow below guidelines:

51

In order to exit the option of using drying program libraries, disable access to
libraries in moisture analyzer’s menu (see point 9.3. of this user manual).

Changing settings of any drying program (auto switch off mode, drying
mode, drying temperature, data to be displayed and printed) in the library,
requires selecting one of drying programs, and then acting as specified in
point 14: DRYING PROCESS WITH USE OF SHORTENED MENU.

Additionally, each drying procedure stored in the library allows for using an option of
sample mass control. When enabling the option, a moisture analyzer software
informs the user whether the mass to be tested is within set thresholds, regarding
the mass and tolerance values, on condition that the parameters were determined
for the sample. The sample mass control is visualized by displaying pictograms LO,
OK or HI on moisture analyzer display. The option is implemented for information
purpose only and facilitates a user in preparing the same or very similar sample to
be tested, thus increasing repeatability of measurements. If the pre-determined
mass control criteria are not met (i.e. pictograms LO or HI are displayed), the
moisture analyzer still starts the drying process. Settings of mass control option are
provided below.

15.1. Sample mass control

Sample mass control option is active only in case of enabled access to library
of drying programs – P6-01 Libr (parameter set to YES).
The mass control value and tolerance value are set in the following way:

19. PRINCIPLES OF USE

For measurement temperatures ranging from 161°C to 250°C time interval for
temperature meintenance is estimated proportionally as follows, 60 min for 161°C –
20 min for 250°C.

For drying process in temperature 250°C, Max temp is maintained for 20 min, next
the program automatically lowers the temperature to 161°C, without aborting the
drying process.

Time interval for lowering the temperature to 160°C is 20 min.
For drying mode Quick overdriving Max drying temperature is 30% but no more

than Max default temperature.
For drying mode Step time interval for temperature maintenance is limited to 20

minutes for particular steps.

PRIOR VERSION OF MOISTURE ANALYZER

Parameter <P6-06Preuer> must be set to value <YES>.

59

Parameter allowing the moisture analyser to be operated by means of a prior
version of the software (valid since June 2013). Upon setting parameter <P6-
06Preuer> to value <YES > the moisture analyzer operates like its prior version
(produced before June 2013) in terms of drying temperatures and drying process
control (when operating in similar temperature conditions).
This allows using drying process settings the same like for previous moisture
analyzers of this series. Thus the user does not have to set the drying parameters
for a newly purchased product, he may work with already set ones.
