After a certain period of use, various problems may occur with the weighing scale, such as inaccurate or unstable weighing data, bending of the weighing platform, automatic shutdown during use, etc. These problems are often caused by non-standard usage or poor maintenance, which is why we have been emphasizing various maintenance and protection measures for the weighing system. The weighing scale always shuts down automatically during use, and a large part of the reason is due to abnormal power supply voltage in the circuit, abnormal voltage inside the weighing platform, or a malfunction in the weighing sensor of the scale, as well as problems with the capacitor components on the circuit board.
