Electronic scales have become a very popular weighing equipment, which is mainly divided into commercial electronic scales and industrial electronic scales . The accuracy of industrial electronic scales is generally high, so the cost is relatively high, so the protective measures should be done more rigorously. We have also said in the previous article, today we will add some maintenance methods for electronic scales :
1. When charging is required, pay attention to whether the rated output voltage of the external adapter power supply (buck power supply) matches the scale display, ¢ 6 the polarity of the plug is correct (the voltage can have a positive or negative difference of 10%) Note that the initial voltage rating of the adapter is 110V or 220V, so 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 charging current will not be charged.
2. The meter prompts to recharge when charging, do not need to increase the number of charging (because the good lead-acid battery zui can only charge and discharge 350 times, the general product is about 300 times) otherwise it will reduce the battery life, give Customers bring economic losses. The scales, table scales, and small floor scale monitors are all 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 battery life can be calculated as 24000~36000. hour.
3. When working in an environment with high humidity, dust and temperature difference, it should promptly eliminate suspicious interference and do the corresponding maintenance work such as moisture, cooling and dust removal. Especially for moisture-proof scales, check the sealing parts of the scale body regularly, such as: whether the waterproof surface is broken, whether the base is damaged, whether the screws are tight, whether the charging plug is damaged, or the moisture-proof agent in the battery compartment (originally white) Check the sealing performance of the battery cover when it turns green. If any of the above parts are abnormal, the sealing part should be treated, the parts replaced, and the sealing strip replaced. (If the seal is found to be inelastic, it must be replaced. When the seal is pressed, the joints should be aligned, squeezed, and not folded.) Tighten the screws in a diagonal order. (Strong force should be appropriate, not too strong, so as not to cause an extended fault range).
4. It is necessary to check the sensor regularly to check whether it is damp, whether it is oxidized, whether there is any foreign matter around the moving part, and when it is found to be abnormal, it should be cleaned and maintained in time. The anti-corrosion measure of the simple moisture-proof scale is to apply a layer of butter on the protective layer of the sensor elastic beam (white silicone part), which can prevent moisture. Note: Do not apply butter to sensitive parts of the elastic beam.
