Common sense of Digital watches. When the temperature of electronic watches is 25-28 C, the time error of one day and night is less than one second. When the temperature is below 0 C or above 50 C, it will slow down by two seconds every day and night. At the same time, when the temperature is as high as 60 C, the LCD will become black, and when the temperature drops below 0 C, the LCD will lose its display function. Therefore, in winter, the electronic watch can only be worn on the wrist, * the human body's constant temperature to maintain its normal timing. In addition, high temperature and low temperature can also cause leakage of battery and corrosion of machine core.
The batteries of electronic watches can generally be used for more than one year, but the lighting consumes a lot of electricity, which is equivalent to more than one hour of time when it is turned on for one second. When the battery is almost finished, the light will dim, or the digital display will dim or even disappear when it is turned on. When replacing batteries, if you don't know how to repair watches, you should send them to the repair shop for installation. Moreover, the battery specifications are not standardized, and there are many kinds of batteries, which can not be used at will.
Electronic watches should pay attention to: press the button not too hard to avoid failure; LCD plate used for five to seven years need to be replaced; batteries without electricity should be removed in time to avoid fluid corrosion of the machine core. When it is found that the lamp is not on, the button is out of order, and there is a sudden big error in timing, it should be repaired in time. It may be that the solder joints of the components are not in good contact or have been removed.
Electronic watches, especially digital watches, generally have poor waterproofing performance. Although some of them have the words "waterproof" printed on the instructions or back cover, they should try to avoid contact with water.
Electronic watches are different from mechanical watches in structure. They are all electronic circuits and components. If water enters, it will be "catastrophic" and scrap the whole watch. Especially the LCD board and the integrated line are not only afraid of water, but also suffer from dampness, which will lead to faults over a long period of time. Therefore, it is better to take off the watch when washing your face and laundry. When it rains, keep the rain from splashing. If it is found that the electronic watch is in water or that there is water vapor on the inner wall of the watch cover, it should be sent to the watch repair shop immediately for dewatering and dehumidification treatment.
