JY70P Ⅱ型电感耦合等离子体发射光谱仪一直使用正常。偶而也出现过一些故障,均能很快修复。现将两例较特殊的故障现象及排除办法介绍如下: 一、由于功率管的故障, 导致仪器无法点火 1.故障现象 仪器点火,正常运行后,偶然发生“放电”现象,即在仪器的下方传来“啪”的一声,很似鞭炮的响声。同时高压掉下,仪器熄火。重新加高 JY70P Ⅱ Inductively Coupled Plasma Emission Spectrometer has been using the normal. Occasionally there have been some failures, can be quickly fixed. Now two more specific symptoms and troubleshooting are described below: First, due to power tube failure, resulting in the instrument can not be ignited 1. Symptoms Instrument ignition, normal operation, the accidental “discharge” phenomenon, that is, below the instrument Came “snapped” sound, it sounds like firecrackers. At the same time the high-voltage drop, the instrument flameout. High again
