Sensors are usually composed of multiple strain gauges. When an object exerts pressure, the strain gauges will deform, thus changing the resistance value. The sensor will convert the changes of these resistance values into electrical signals, which will be transmitted to the processor in weighing scale for processing, and finally show the weight of the object.
Therefore, if you need to check whether the sensor of Yuedi electronic scale works normally, you can open the cover under the scale and check the status of the sensor. If the sensor is damaged or loose, the accuracy of the scale may decrease, or it may not work properly. If you are not sure how to check or replace the sensor, it is recommended that you contact professional maintenance personnel or contact Yuedi after-sales service center for consultation.
