They inform and warn a user of possible dangers. Ignoring the safety warnings may cause injuries, damage of the moisture analyzer, its inappropriate operation and errors of measurements. 2.1.1. Warning descriptions WARNING Dangerous situations of high risk.
Acid / Corrosion Danger Flammable or explosive substances Toxic substances Hot surfaces 2.2. Safety information CAUTION! The use of moisture analyzer MA 3Y regardless of both, safety information and user manual guidelines may cause health 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.
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.
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.
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.
- with the supply in the mains to which the moisture analyzer will be plugged in, replecemant of halogen lamps can only be carried out by authorized service, protect moisture analyzer against contacts with liquids, it might lead to electrocution, fire, emission of substances containing toxic or caustic vapour, emission of explosive substances. 2.6.
2.9.1. Protective clothing The use of protective clothing is highly recommended while working with the instrument in order to take safety precautions against potential hazards resulting from tested samples and ingredients. Use the following while carrying out tests: • protective apron, • protective glasses, • protective gloves (while working substances).
• • • Ambient relative humidity should not exceed 80% in the temperature up to 31°C, and decrease linearly to 50 % of relative humidity in temperature 40°C, A moisture analyzer should be located on a stable wall console desk or a stable working table which is not affected by vibrations and distant from heat sources, Take special safety measures when weighing magnetic objects, as part of the balance is a strong magnet. 4.2.
When assembling the pan supporter (bracket) pay special attention to the correct positioning of its mandrel. The mandrel features a cut for its unique positioning against the pan handle, thus preventing their contact and friction.
4.6. Plugging to mains A moisture analyzer can be plugged to mains only by means of original power cord, which comes standard with the moisture analyzer. Rated voltage (specified on device’s data plate) must be compatible with mains rated voltage. The power cord can be connected only to socket with ground contact.

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.
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 AuE = Slouu AuE = Fast - (normal) – normal operation conditions, - (slow) – harsh operation conditions – vibrations, etc.
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.
9.3. Access to library of drying programs In order to use the library of drying programs set parameter to value : no YES - libraries of drying programs disabled, - libraries of drying programs enabled.
9.4. Backlight of measurement result (display backlight) The function enables switching on and off backlight of measurement result on the display. OFF On Aut - backlight disabled - backlight enabled - 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.
9.5. Brightness adjustment of display backlight 100 20 no - maximum display brightness - minimum display brightness - display brightness disabled 9.6. “beep” sound – reaction on pressing a function key bEEP = On bEEP = OFF - signal of pressing function key enabled, - signal of pressing function key disabled.
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.
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 – ordering unloading of the weighing pan (the weighing pan must be empty). When the weighing pan is empty press Print/Enter key. The moisture analyzer initiates adjustment procedure.
10.2. Adjustment test Adjustment test is a comparison of mass of an adjustment weight with the value of last adjustment saved in moisture analyzer’s memory. This process is automatic and its result is previewed on the display (if a moisture analyzer is connected to a computer or a printer through RS 232 interface, data on adjustment test is printout – only if corresponding option has been enabled in moisture analyzer’s settings).
10.3. Drying chamber adjustment Special adjustment set, which is an atypical accessory of a moisture analyzer, is used for temperature adjustment. 1. 2. Thermometer Thermometer holder with a holder shield Adjustment is a process that aims at calibration of temperature sensor of a drying chamber.
