2.2. Precautions WARNING!

The use of the moisture analyzer regardless of both, safety information and service manual guidelines may cause health damage and even death. WARNING:

Nominal voltage for a moisture analyzer is 120V AC. 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. Voltage range for moisture analyzers marked with AC 120V symbol:

100 V120 V, 50/60 Hz, 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 400C. 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 weighing 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:

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!

Consult the dealer or an experienced radio/TV technician for help. 2.3. Intended Use The moisture analyzer of MA X2 series is designed to determine: relative moisture content in small samples of various substances, dry mass content in small samples and mass of weighed objects. The moisture analyzer ensures fast and precise determination of sample's moisture content. With use of a graphic touch screen the operation and measurement is simplified. A moisture analyzer can be used to determine moisture content of different materials. At the initial stage of measurement, the device precisely determines the mass of an object placed on instruments 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.

- 9 -

Compared to conventional methods of humidity content determination of various substances, application of moisture analyzer considerably shortens measurement time and simplifies testing procedure. MA X2 moisture analyzer allows setting multiple parameters which influence the procedure of moisture content determination in a sample, such as: temperature, time, drying modes, etc. 2.4. Good Weighing Practice CAUTION!

Do not open the drying chamber during drying process. Moisture analyzer features a halogen lamp which is a very powerful heat source. Thus, operator 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). MA X2 moisture analyzer is not intended for dynamic weighing. Even if small amounts of a sample are added to or taken off the weighing pan, the mass readout should only be taken on stabilization of measurement result (upon displaying Do not place any magnetic materials on the weighing pan. 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 explosion!

This moisture analyzer is not adjusted for operation in explosive areas. There must not be any modification made to the moisture analyzer. pictogram). 2.5.

Cleaning the weighing pan while still installed may cause damage of the measuring system. Cleaning ABS components:

- 13 -

To clean dry surfaces and avoid smudging, use clean non-colouring cloths made of cellulose or cotton. You can use a solution of water and detergent (soap, dishwashing detergent, glass cleaner). Gently rub the cleaned surface and let it dry. Repeat cleaning process if needed. In the case of hard to remove contamination, e.g. residues of adhesive, rubber, resin, polyurethane foam etc., you can use a special cleaning agents based on a mixture of aliphatic hydrocarbons that do not dissolve plastics. Before using the cleanser for all surfaces we recommend carrying out tests. Do not use cleansers containing abrasive substances. Cleaning anti-draft chamber panes:

Select dissolvent depending on a dirt. Never soak the glass panes in alkaline solutions since they interact with glass and may cause damage. Do not use cleansers containing abrasive substances. For organic dirt use acetone first, next use water or detergent. For other than organic dirt use diluted acid solutions (soluble salts of hydrochloric or nitric acid) or base solutions

(ammonium or sodium base). To remove ACIDS use protophilic solvent (sodium carbonate), to remove BASE use protogenic solvent (mineral acid of various concentration). In case of heavy contamination use brush and detergent, nevertheless avoid detergents containing large and hard molecules which could potentially scratch glass panes. At the end of the cleaning process rinse the pane using distilled water. Use soft brush with wooden or plastic handle exclusively in order to avoid risk of scratches. Do not use wire brush. Rinsing is a necessary cleaning process stage allowing to remove remaining soap, detergents and other cleansers from the panes prior their reinstallation. After preliminary cleaning process stage, rinse the pane using running water first, distilled next. Avoid drying the panes either using paper towel or forced air circulation since some fibres, grains or contamination of other type could permeate into the panes thus causing weighing errors. We do not recommend using driers when drying measuring glass tools. It is a frequent treatment to leave glass components on a rack to dry. Cleaning stainless steel components:

Avoid using cleansers containing any corrosive chemicals, e.g. bleach (including chlorine). Do not use cleansers containing abrasive substances. Always remove the dirt using microfiber cloth to avoid damage of protective coating. In case of a daily maintenance:

1. Remove the dirt using cloth dipped in warm water.

- 14 -

2. For best results, add a little bit of dishwashing detergent. Cleaning powder-coated components:

For preliminary cleaning process stage you need running water or wet sponge featuring large holes, this will help you to remove loose, heavy dirt. Do not use cleansers containing abrasive substances. Next, using cloth and cleanser-water solution (soap, dishwashing liquid) gently rub the cleaned surface. Avoid using cleanser without water since it may result with damage of the cleaned surface, please mind that large amount of water mixed with cleanser is a must. Cleaning Aluminium Components While cleaning aluminium components use products acid by nature, e.g. spirit vinegar, lemon. Do not use cleansers containing abrasive substances. Avoid using hard brush, this may cause scratches. It is recommended to use microfibre cloth. While polishing the surface use circular movements. Use clean, dry cloth to make the surface shine.

Operation description MA X2 moisture analyzers MA X2 moisture analyzers comprise a precision balance and a drying chamber surrounding a weighing pan joined together. High resolution weighing module is designed to provide quick and precise measurement of a particular sample weight, independently from its thermal condition. Module stabilisation is obtained using special algorithm controlling halogen lamp or infrared lamp operation. The general rule of operation is to measure the mass of evaporated water from a sample 3 placed on a weighing pan 4 during heating it by a heating element 4 (halogen or infrared lamp). The whole process is controlled by a digital system using the thermometer 5 and changes in mass measured by the electromagnetic weighing cell 5. Precise measurement of analysed product mass is guaranteed due to an electromagnetic weighing cell 1. Measurement of the product mass is realized in accordance with the following equation:

F= mg m product mass, g on-site gravitational acceleration Product mass change during heating is analyzed by data processing systems operating in accordance with a unique algorithm. The increase of product temperature aiming to isolate and determine water contained within product structure takes place in the drying chamber. Inside of the chamber there is a weighing pan 2, permanently fixed to the weighing cell 1. In the course of production the moisture analyzer is calibrated using mass standards, traceability is accounted for. This allows to link the gravitational force with the 1 kilogram mass standard. Due to the above, upon placing the sample 3 on the weighing pan 2 it is possible to present the gravitational force (F = mg) on a moisture analyzer display as a weighing result expressed in gram. Increase of product 3 temperature is brought about with use of a precisely controlled heat source 4, built into the top part of the drying chamber. Weighing principle 1, 2 parallel guides 3 - vertical elastic element 4 leverage system 5 fulcrum 6 permanent magnet 7 air coil 8 air gap 9 position sensor 10 load receptor The operating principle of MA X moisture analyzers consist in electromagnetic compensation of the force of gravity applied to the load receptor 10. Generally the rule of operation is to keep the whole unit in equilibrium by generating an adequate current Ic that flows through air coil 7. If a load is applied to the weighing pan, it generates a force of gravity related to the mass of the object on the load receptor 10. The leverage system 4 to which the air coil 7 and position sensor 9 are attached changes position so that the unit becomes unbalanced. Electronics detect the position sensor imbalance and reacts by changing the current Ic. In other words, said force causes a deviation of the system from equilibrium, the deviation being transferred by the mechanical system to the coil placed in a magnetic field of a permanent magnet 6 placed within the actuator. The air coil 8 can move freely in the air gap 8 according to leverage system 4 movements. The weighing mechanism in moisture analyzers MA X is hybridic, made of many parts linked by screws. The position of the coil in the field of the solenoid actuator is detected by the position sensor 9. Due to the change in signal from the position sensor 9, the value of the current Ic flowing in the coil also changes, with this operation the mass measurement system regains its initial equilibrium with another Ic value. The precise measuring resistor converts the coil current into voltage. The measured value of the voltage is transferred to an A/D converter which supplies the digital value of the measurement signal and transfers it to a microprocessor. The digital signal related to measured mass is then filtered (software). Owing to filtering, demanded resolution is provided. Thus prepared measurement signal is corrected by factors accounting for changes occurring within mass measuring system, which changes are a result of temperature variation. Next, in order to get accurate linear relation between measured load and measurement signal value, the signal is subjected to so called linearity correction. At the end the measurement signal is scaled using adjustment coefficient, this is to provide weighing result, displayed on the screen. The weighing result is considered to be stable when it varies less than specified by stability criterion value described below. All operations mentioned here are performed by embedded software. The weighing result is displayed on the LCD display. The weighing results can be saved in the internal memory or passed to other devices via interfaces. One of those interfaces is wireless. FCC certified module is applied to connect the device to an external WiFi network. Description of grounding Fig 1. Models without internal calibration Fig 2. Models with internal calibration The device is supplied from the mains: 100 -120V AC 50 / 60Hz. The device is connected to the mains via a 3-core cable with a PE protective conductor. On the 516R or 508R power supply board, the mains voltage is converted to 12V DC using the IRM-15-12 isolating AC / DC converter. In case of internal calibration models the mains voltage is 120 V AC is applied to 509R PCB and further directed to 508R PCB without changes. The voltage is lowered to the desired values by DC / DC converters to suit the components on the 513R motherboard, 515R converter board and 395R position sensor board. Additionally, in case of models with internal calibration, the DC voltage is passed to 434R PCB responsible for controlling the internal calibration process. All interface connector housings are connected to PE potential. All metal housing elements that the user has access to are connected to the PE potential. 12V DC voltage goes to the 513R motherboard. Then the voltage is re-processed to power the individual elements: processor, lcd, wifi module etc. Description of anthenna The anthenna for the third party FCC certified WiFi module is made as a PCB track on the modules PCB.
