Our factory produced the camera in 1974, so it was in urgent need of testing instruments. At that time, the testing instruments did not have any manufacturing plants yet. Therefore, under the guidance of Chairman Mao Zedong and Chairman Mao, we should promote the spirit of independence and self-reliance and lack of forming materials and electronic instruments Under the conditions, began trial production, trial success in the same year. Appraisal by the relevant departments put into use. 76 years on the basis of the original from the performance accuracy and ease of use considerations, to be improved, trial success of 10 sets, the national metrology department identified qualified. (1) Working principle: The principle of photoelectric conversion. (2) Performance characteristics The instrument is all-transistor type, using the plug-in building blocks
