Electronic scale daily maintenance and repair: (1) keep the electronic scale machine clean. Electronic balance is a kind of precise measuring instrument. Keeping the whole machine clean is of great significance to prolong its service life and improve the measuring accuracy. To keep the parts of the electronic scale do not accumulate dust and oil, to keep the mobile joints flexible, to prevent rust phenomenon, in the harsh environment such as dust and corrosive gas should be used in time dust, cleaning. Often check whether there is collision, cracks, fasteners in various parts are loose, if there is an anomaly should be dealt with in time. (2) To avoid the electronic scale by violent push and collision, impact. The inside of the electronic scale is composed of many electronic components, such as integrated circuits, quartz crystals, display devices, sensors, etc., when the electronic scale is subjected to severe external force, it may damage these elements, accessories, resulting in the failure of the electronic scale, affecting the accuracy and affecting the normal use of the scale body and other items to avoid strong collision or fall from a height, the display instrument should be handled lightly, carefully managed. Can not be exposed in strong sunlight for a long time, to prevent unnecessary loss, weighing display fixed in the vibration of the more severe place, to take vibration reduction measures, so as not to affect its reliability. (3) Do not disassemble the parts on the electronic scale at will during the normal use of the electronic scale, do not disassemble the parts on the electronic scale at will, let alone remove the sensor seal and the integrated circuit and other components on the instrument, the necessary maintenance must be carried out under the guidance of the relevant technical personnel or after having certain maintenance knowledge to prevent the expansion of the fault. (4) Management of electronic weighbridge. Electronic scale is a precision and valuable instrument, it is recommended that users develop the necessary management system, the implementation of special, special management, special, establish the necessary use and maintenance records, long-term do not need to be fixed storage, sunscreen, moisture-proof, dustproof. (5) The battery pack should be charged in time. The battery pack equipped with the electronic scale is a rechargeable battery, its capacity is limited, long-term use or work in the display of underpower indication, should be timely to charge the battery, so as to avoid excessive discharge of the battery, affecting the battery life, often check whether the battery packaging is damaged, whether the lead is intact, to prevent short circuit, damage to the battery and electronic scale circuit. For the battery charging method, refer to the operating manual of the electronic scale or the relevant chapters of this book.
