济南历下微机应用研究所生产的 WFJ-1增强型发动机检测仪是交通部推荐的检测设备。几年来,该仪器对监控汽车维修质量和保证在用车辆技术状况良好发挥了很大作用。但是,由于电子产品易受干扰,故障多,在一定程度上影响了检测精度和检测效率。这就要求我们注意积累经验和总结,从大量的检测实践中找出规律,以指导检测工作。笔者将该仪器的 Jinan calendar under the Institute of Computer Applications WFJ-1 enhanced engine detector is the Ministry of Communications recommended testing equipment. Over the years, the instrument has played a significant role in monitoring the quality of vehicle maintenance and ensuring that the technology in use is in good condition. However, as the electronic products are susceptible to interference, the number of failures is large, which affects the detection accuracy and the detection efficiency to a certain extent. This requires that we pay attention to the accumulation of experience and summary, from a large number of detection practices to find out the law to guide the detection work.
