1. When the electronic scale needs to be charged, pay attention to whether the rated output voltage of the external adapter power supply (step-down power supply) matches the scale "meter", and whether the polarity of the plug is correct (the voltage can be 10% positive or negative) Poor) Also note that the initial rated voltage of the adapter is 110V or 220V, don't make a mistake. (The no-load voltage of 9V should be greater than 12V. Note that the rated power of the transformer should be greater than 15W, and the quality of the silicon steel sheet should be good. Otherwise, the current will not be charged.
2. The weighing indicator prompts to recharge when it needs to be charged. Don't increase the number of recharges needlessly (because the best lead-acid battery can only charge and discharge at most 350 times, and the general product is about 300 times, otherwise it will reduce the service life of the battery. , Bringing economic losses to customers. The benches/scales are equipped with 6V/4A batteries. After fully charged, the LED display can be used for 80 hours, and the LCD display can be used for 120 hours, so that the normal service life of the battery can be calculated 24000~36000 hours. For example, if a unit uses a weighing scale to work 12 hours a day, it can be used for 6 days after being fully charged. Do not make the battery voltage lower than 5.5V, otherwise the battery will not be charged with current and the battery will be scrapped. When the electronic scale is not used for a long time, it should be charged once every two months to avoid over-discharge of the battery)
3. The charging circuit of each weighing instrument company is intelligent. The color change of the charging indicator reflects the working state of the battery being charged. It is basically "Charging required (dark red) → orange yellow → yellow → yellow green → green ( Complete the charging process) Usually the charging time is 12~15 hours.
4. When working in a humid, dusty, and large temperature difference environment, you should promptly eliminate suspicious interference and do corresponding maintenance work such as damp removal, cooling, and dust removal. Especially for moisture-proof scales, the sealing parts of the scale body should be checked regularly, such as: whether the waterproof surface is broken, whether the base is damaged, whether the screws are fastened, whether the charging plug is damaged, whether the moisture-proof agent (originally white) in the battery compartment is When it turns green, check the sealing performance of the battery cover. If there is any abnormality in the above part, deal with the sealing part, replace the accessories, and replace the sealing strip. (If the sealing strip is found to be inelastic, it must be replaced. When pressing the sealing strip, the interface should be aligned, squeezed tightly, and there is no discount.) When tightening the screws, tighten them in a diagonal order. (Appropriate force should be used. Excessive force cannot be used, which will expand the scope of failure).
5. The sensor should be inspected regularly to check whether it is damp, whether it is oxidized, whether there are foreign objects around the moving part, and clean and maintain it in time when an abnormality is found. The anti-corrosion measure of the simple moisture-proof scale is to apply a layer of butter on the protective layer of the elastic beam of the sensor (white silica gel part), which can prevent moisture. Note: Do not apply butter to the force-sensitive parts of the elastic beam.
6. The circuit board in the electronic scale should be kept clean and free of all kinds of dust and debris. If there is moisture, you can apply a layer of insulating varnish after drying to facilitate the protection of the circuit board and improve the moisture-proof insulation of the circuit Performance, the connectors should be in good contact, and the wires should have no bad contact or leakage. When replacing circuit components, it must be maintained and replaced by professionals, and the user is not responsible for tampering.
7. The shell of the electronic scale (instrument) is basically made of plastic products, so in daily use, it should be kept away from corrosive solvents and gases, which can extend the service life. Avoid strong impact, squeeze, etc. Keep it clean at all times and solve problems as soon as they are found.
8. Electronic weighing instruments should be avoided as far as possible from working in places with extremely high or extremely low temperatures. If they must work in a harsh environment, they should be static for a period of time (30 minutes) before using. This is caused by sensors and electronic components. Determined by the temperature characteristics, they must have a temperature adaptation process before they can work normally, otherwise the weighing will be inaccurate.
