Wuyi Dahe Electronics Co., Ltd. has a wealth of electronic scale production experience, now we teach you some electronic scales of day-to-day maintenance knowledge.

　　1. When the electronic scale needs to be recharged, to pay attention to the external adapter power (Step-down power supply) rated output voltage and the scale "table" match, ￠6 plug polarity is correct (voltage can have 10% positive and negative) Also note that the initial rated voltage of the adapter is 110V 220V, do not make mistakes. (9V no-load voltage should be greater than 12V, pay attention to the transformer rated power is greater than 15W, the quality of silicon steel is better. Otherwise, it will cause the current to be charged.

　　2. Weighing the display of the instrument to recharge the charge, do not unnecessarily increase the number of charges (because the best lead-acid battery can only charge and discharge 350 times, the general product is 300 times or so, otherwise it will reduce the battery life, to the customer to bring economic losses. Taiwan case/scale are equipped with 6v/4a battery, sufficient power, LED display can use 80 hours, LCD display can use 120 hours, so that the normal life of the battery can be calculated 24,000-36,000 hours. such as: a unit used weighing scales to work 12 hours a day, sufficient electricity can be used after 6 days, do not make the battery voltage below 5.5V below, the battery will be charged with current, resulting in battery scrap. Electronic scales for a long time, every two months should be charged once, lest the battery over discharge)

　　3. Each weighing apparatus company's charging circuit is intelligent, through the charge light color change, reflects the battery charged the working condition, basically is "needs the charge (deep red) → orange yellow → yellow → yellow green → Green (completes the charging process) usually the charge time is 12-15 hours can."

　　4. For the work in the humid, dust, temperature difference in the environment, the timely elimination of suspicious interference and do the corresponding drainage, cooling, dust and other maintenance work. Especially moisture-proof scale, to regularly check the sealing parts of the scale body, such as: whether the waterproof crust is broken, the base is broken, whether the screw is fastened, whether the plug is damaged, the battery compartment of the moisture-proof agent (formerly White) to turn green should check the sealing performance of battery cover. The above parts should be handled in case of abnormal sealing parts, replacement of parts, replacement of sealing strips. (If the sealing strip is found to be inelastic, it must be replaced, when the sealing bar is pressed, the interface should be aligned, tight, no discount) tighten the screws in the diagonal order. (Force to be appropriate, not to force too hard, causing the expansion of the fault range).

　　5. To regularly check the sensor to check whether it is damp, whether oxidation, the movement of the area around whether there are foreign bodies, found that abnormal should be timely clean-up and maintenance. The anticorrosion measure of the simple moistureproof scale is to apply a layer of butter to the protective layer of the sensor's elastic beam (the White Silica gel part), which can play the role of Moistureproof. Note: The butter must not be applied to the force sensitive part of the elastic beam.

　　6. For electronic scales in the circuit board, should be kept clean, not all kinds of dust debris, such as damp phenomenon, can be dried, brushing a layer of insulating varnish, in order to facilitate the protection of circuit boards, improve the circuit of moistureproof insulation performance, plug-ins should be in good contact with the wire without adverse or leakage phenomenon. Replacement of circuit components, must be for professional maintenance replacement, the user is not responsible for tampering.

　　7. Electronic scales (meters) of the shell is basically the use of plastic products, so in the day-to-day use should be careful away from corrosive solvents and gases, this can prolong the service life. Should avoid strong impact, squeeze and so on. Keep clean at all times and find problems in a hurry.

　　8. Electronic weighing apparatus should avoid long-term work at extremely high temperature or very low places, as far as possible if you must work in a bad environment, should be stationary for a period of time (30 minutes) before use, which is determined by the temperature characteristics of sensors and electronic components, they should have a of the temperature to adapt to the process to normal work, otherwise there will be the phenomenon of weighing.
