Description
technical field [0001] The invention belongs to the technical field of electronic calibration equipment, and in particular relates to electronic balance zero adjustment equipment, in particular to a photoelectric conversion device for adjusting the balance position of an electronic balance, which can improve the balance position of the electronic balance. Background technique [0002] A balance is a kind of weighing instrument made using the principle of leverage. When using an electronic balance, the balance needs to be at the zero point of the balance position. The traditional method is to measure the photoelectric cell of the beam through light-emitting diodes and differential photodiodes (that is, photoelectric conversion devices). Therefore, in the production and assembly process of the electronic balance, it is particularly important to adjust the photoelectric conversion device so that the light emitting diode, the differential photodiode and the photoelectric cell of ...
