We should know a lot about the so-called traditional weighing equipment. For example, the hook scale we used before, a beam with a weight, mainly uses the principle of leverage and force balance to measure weight. This principle is used in traditional weighing equipment. It is widely used in China, as well as scales, which use increasing and decreasing weights to test the weight of objects. With the progress of the times, the traditional weighing equipment gradually shows its limitations and shortcomings in the needs of economic life. It will be a waste of manpower to weigh large and extra-large objects, and the weighing is also very complicated. Like some small and micro objects, traditional scales cannot measure at all, and the accuracy is too low.
The electronic scale is a scale with high precision and a wide range of measurement developed to meet the needs of economic and social development. The main components of the digital scale are divided into three parts, one is the scale body, the other is the sensor, and the third is the display. Its basic working principle is that the object passes through the scale body, causing the scale body to generate pressure, and this pressure is transmitted to the sensor. The sensitive beam on the sensor will be deformed under the pressure, and the signal generated by the deformation of the sensor will be converted into identifiable data. Then the data is transmitted to the CPU (central processing unit) for calculation, and the CPU transmits the calculation result to the display. The whole process can be summed up in one sentence as converting the force into a recognizable electrical signal, and then converting the electrical signal calculation into a unit of weight. Electronic scales are not only used for weighing, but can be divided into pricing scales, counting scales, and weighing scales according to the scope of application.
1. Please place the electronic scale on a stable and flat table or the ground, and do not place it on an unstable table or stand.
2. The power switch is located at the bottom right of the electronic scale. When the power is turned on, do not place items on the weighing pan, and warm up the machine for more than 2 minutes before use (the longer the warm-up time, the higher the accuracy). If the weight is not zero just after starting up, wait for a while, or restart the machine to set it to zero.
3. The "zero setting" on the electronic scale means that after weighing an item, the next time it is called a different item, it will be set to zero, and the electronic digital scale will re-measure and calculate the price.
4. Tare and tare weight is the basic function of electronic scales. Its accurate use is to put the auxiliary containers on the scale platform, such as small pots, and other auxiliary items, and put the auxiliary containers that help to weigh on the weighing platform. On the scale, then press the "tare" button, the weight value will be replaced with the zero of the electronic scale, and then the weight of the items placed on it will be displayed as the net weight value.
1. It is strictly forbidden to rain or wash with water. If it gets wet accidentally, wipe it with a dry cloth. When the machine is not functioning normally, send it for repair as soon as possible.
2. It is strictly forbidden to beat, hit and press heavily.
3. Do not place in high temperature and humid environment (except for special waterproof and anticorrosion scales).
4. If the electronic digital scale is not used for a long time, the machine must be wiped clean, put in a desiccant and wrapped in a plastic bag, and dry batteries should be used. Otherwise, the battery will rust and corrode the electronic scale.
