USER MANUAL 7 5. General description Moisture analyzers ATS and BTS are designed for fast and precise moisture determination of a sample based on mass loss during heating process. Drying proces parameters are set by user on the basis of law norms, available chemical-physics data or they are matched experimentally. Parameters table for typical materials is contained in the A appendix.

USER MANUAL 9 8. Preparation to work During heating, the halogen heaters 1 warm up to very high temperature. When drying chamber is opened avoid touching the heaters as it may cause severe burns or damage the heaters! Dryer chamber cover 3 heats up to 60°C, but perforated cover may heat up over 100°C.
USER MANUAL 1. Take all contents out of a package: the moisture analyser and packed separately: the tin pan shield, single use pans, the pan handle and the pan support. It is recommended to keep the original scale package in order to transport the moisture analyzer safely in future. 2. Place the moisture analyzer on a stable ground not affected by mechanical vibrations and airflows. 3.
USER MANUAL 11 Removing the glass (to clean or remove radiators): 1. Open the moisture analyzer chamber. 2. Raise glass 13 until it will be released from lower glass supports 14 . 3. Remove the glass by diverting lower limb (look at the picture above). When temperature during initial heating exceeds 105°C or heating time is longer than 3 minute, terminate initial heating with STOP key and check if the temperature sensor 2 works properly and if both halogen heaters light 1 (see chapter 15).
USER MANUAL 12 9. Interfaces The moisture analyser is equipped with RS23C interface to connect a printer or a computer and with PS2 port to connect an external computer keyboard.

General working rules During transportation remove the pan, the pan support and the pan shield and place it in a separate package.. 1. Distribute a sample all over the pan.
USER MANUAL 13 Moisture in substances is an essential quality factor of technical and economical importance. Methods of determining moisture may be grouped in two main categories: absolute and deductive. Absolute methods are based on simple relations, e.g. weight decline during drying. Thermogravimetric analysis used in moisture analyser LEXUS AXIS is an example of this method. Deductive (indirect) methods measure physical quantity related with moisture, e.g.
USER MANUAL 14 method of homogenizing a sample is mixing. The other method is to draw few samples from different but specific points in a substance and calculate an average value. Another – to draw few samples from different points in a substance, mix them and draw a sample from the mixed samples. Sampling method depends on the object of a research. For quality purpose many representative samples are analysed.
USER MANUAL 15 Attention: Due to temperature sensor localisation, max sample height is 10mm. When substance ply is too thick, surface layers will be heated too much and internal – not enough. This may result in burning the sample or surface incrustation, which will make drying process difficult and measuring result false. A sample should be placed in uniformed layers 1÷3mm thick, weighing 1÷10g, depending on a substance. 11.
USER MANUAL Sample values for the most common materials are given in the Appendix, however, be regarded only as preliminary data and it is recommended to carry out the procedure for parameters selection for the test material. 11.9 Other practical notes It is preferable to work with the same mass of the sample at each measurement to measure the size of the sample in a reproducible way. It is best to use the same instruments for the application of the sample.
USER MANUAL 17 12. Moisture analyzer start After switching-on the moisture analyser proceeds with self-tests and displays company logo. Next the moisture analyzer is taring (- - - - - -). After taring initial heating starts in order to create proper conditions inside drying chamber. m0-m/m0*100% Td=105°C ts= 10s T= 32.23°C m=0.000g INITIAL HEATING … Initial heating should warm the drying chamber up to 105°C within 3 minute.
USER MANUAL 13. Drying parameters settings In order to achieve proper density measurement results following parameters should be set: - Drying temperature (to 160oC), - Mode : time mode (ends after inscribed time) or short mode (ends after fulfilling drying criterion), - Calculation method – humidity calculation formula, - Samples quantity (only for short mode), - Sampling interval – interval between successive mass measurements (1÷180s.), - Drying time (1s.
USER MANUAL 13.1 Setting drying temperature During setting drying temperature set successively values of individual digits.
USER MANUAL
USER MANUAL 21 13.2 Calculation methods Humidity may be calculated upon the basis of various mathematic formulas, defined in balance – drier as Calculation method: 1. Relative humidity, defined in relation to initial mass w [%] = m0-m/m0*100% , where m0 – initial mass, m- current mass 2. Relative humidity, defined in relation to current mass w [%] = m0-m/m*100% , 3. Percent current mass content in sample w [%] = m/ m0*100% .
USER MANUAL 22 13.3 Drier working modes, drying time, sample time During the balance – drier operation sampling of the mass on the pan takes place. Sampling time is set by the user, according to drying process speed. As a result of sampling the current humidity value is calculated and displayed. Measurement is finished depending on selected Drying mode: 1. In Time mode total humidity measurement time (Drying time) is defined by the user, 2.
USER MANUAL 23 13.4 Drying profiles Drying profile will be used to optimization of drying process by accommodation a process to physical properties of sample material. Oxidized materials or thickening on the surface need slow or step profile. Resistant materials can use fast profile. The choice of profile and his parameters should be a result of experience with examinated material. DRYING SETTINGS 1. Drying temperature : 120°C 2. Mode : short mode 3. Calculation : m0-m/m0*100% 4.
USER MANUAL 24 13.5 Moisture analyzer memory The moisture analyser enables to save 20 different drying settings.

USER MANUAL 32 The way of entering control thermometer probe to moisture analyzer drying chamber: 2 3 100 o C 1 1 – control thermometer probe 2 – distance sleeves 2x20mm (2 sleeves ensure that position of control thermometer probe is the same as moisture analyzer internal temperature sensor, 1 sleeve – on the upper edge of the single-use pan) 3 – moisture analyzer internal sensor Before executing temperature correction (inscribing T1 and T2 temperature) drying cycle must be made with inscribed T1 tem
USER MANUAL 33 Attention: Moisture analyzer internal thermometer correction is made with internal thermometer and control thermometer on the same level above the sample. The temperature indicated by thermometer situated on some level above the sample can differ from real temperature of the sample. In this case if there is a need for temperature indication correction simply lower the level of control thermometer by removing distance sleeve (picture on page 31 position 2).
USER MANUAL 34 18. Moisture analyser as a balance The moisture analyser may be also used as a normal balance. To switch between analyser / weighing mode press B key. During moisture analyzer work as a normal balance essential influence on measurement result has the proper setting of moisture analyzer level (level indicator is at the back of the device) and precise balance calibration. Setting balance level is important after each putting moisture analyzer into new place .
