重が困難である。 Converting the weight into a mechanical change amount, converting this change amount into the gap between two parallel flat plates arranged in parallel,
For capacitive electronic scales that detect the capacitance generated in this gap as an oscillator parameter, convert the oscillation frequency of this oscillator into the weight value, and display the weight, it is difficult to detect the capacitance due to disturbances. Changes have a significant effect, making accurate weighing difficult.
