What is the reason why electronic devices cannot be turned on normally?

Firstly, it is necessary to determine whether the issue is caused by the fuse (use. power switch, power line, and voltage switching switch), and check if the transformer has AC power

Voltage input and AC power output.

If the electronic balance is equipped with a battery, first remove the battery and then turn it on with AC power to see if it is caused by insufficient battery voltage.

Then check if the rectifier circuit, voltage regulator circuit, and display driver circuit are normal. If there are no issues with the above, check if the processor and accessory circuits are burned out.

Quantitative analysis shows that the balance is fragrant and normal; Whether it is in a horizontal position or in a courtyard, and whether the inside and outside of the glass frame are clean. People use inductive force to balance objects on electronic scales

The balance is called an electronic balance. Its characteristics include accurate and reliable weighing, fast and clear display, and automatic detection system, simple automatic calibration and positioning, as well as stacking force protection for over counting
