故障现象扫描时，一曝光，即中断。瞬间有Ｘ线指示。故障码：２１０１，译码提示：“固件请求后，Ｘ线管电流不存在”。检查与分析计算机提示“无管电流”故障不外乎两类：一是有管电流但因检测电路有问题而未能检测到；二是检测电路正常但确无管电流。由于瞬间曾有Ｘ线指... Fault phenomenon When scanning, an exposure, that is, interrupted. Instant X-ray instructions. Fault code: 2101, decoding prompt: “after the firmware request, X-ray tube current does not exist.” The inspection and analysis computer indicates that the “no-pipe current” fault is nothing more than two types: one is that there is a tube current but it cannot be detected due to a problem in the detection circuit; the other is that the detection circuit is normal but there is no tube current. As there was an X-ray finger...
