НФО—451型测微光度计是我国从苏联引进的一种精密测光仪器。针对在原子发射光谱分析测试应用中该仪器出现的故障以至尚不能正常运行的问题,本文着重就电子线路部分的检修和改进,提出一些粗浅之见,仅供维修和使用该仪器时参考。一、仪器工作原理НФО—451型测微光度计是一种综合电子线路、光学系统和机械传动控制系统的记录式精密光学测绘仪器。其工作原理参阅框图1:
НФО-451 micrometer luminometer is the introduction of a precision photometric instrument from the Soviet Union. Aiming at the problem of failure of the instrument in the application of atomic emission spectrometry test and its failure to operate normally, this paper focuses on the overhaul and improvement of the electronic circuit, and presents some superficial opinions for reference only for maintenance and use of the instrument. First, the instrument works НФО-451 micrometer luminometer is a comprehensive electronic circuit, optical system and mechanical transmission control system of recording precision optical mapping instruments. Its working principle see the block diagram 1:
