仪器仪表在现场维修调试时,往往没有良好的测试设备,通常又要求对出现的问题作出迅速的判断并加以解决。下面介绍维修调试过程中一些具体方法。 1.比较法许多电气电子设备都具有对称性,可通过比较,便能迅速找到故障。在石油钻探过程中,需用气相色谱仪分析井底返出气体的两个参数:总烃和组分。两个检测回路的电路部分完全相同,气路 Instruments in the field of maintenance debugging, often without good test equipment, usually requires the emergence of problems to make prompt judgments and to resolve. Here are some specific ways to repair the debugging process. 1. Comparative Law Many electrical and electronic equipment has a symmetry, can be compared to quickly find the fault. In oil drilling, gas chromatography is used to analyze the two parameters of the bottom-hole gas: total hydrocarbons and components. The circuit parts of both test loops are identical and the gas path
