508型生化自动分析仪是美国 IL 公司生产的一种自动化程度较高的精密分析仪器。它利用微计算机实现自动数据采集、数据处理及自动打印,能够同时完成八个生化项目的测定。只有正确使用和保养仪器,迅速判断和排除使用中的常见故障,才能保证仪器处于正常状态。如果使用人员忽视及时保养仪器就会出些小故障。根据我们的工作实践,将几种常见的故障及排除方法作一介绍,供参考。一、故障现象:定标时打印出的钾钠测定值反复显示“R”,表示数据超出范围。 508 automatic biochemical analyzer is the United States IL company produces a high degree of automation of sophisticated analytical instruments. It uses micro-computer to achieve automatic data acquisition, data processing and automatic printing, can simultaneously determine the eight biochemical projects. Only the correct use and maintenance of equipment, promptly determine and eliminate the use of common faults, in order to ensure that the instrument is in normal condition. If the neglect of the staff to maintain the instrument will be a little glitches. According to our work practices, several common faults and troubleshooting methods for an introduction for reference. First, the fault phenomenon: Calibration of potassium sodium measured values ​​?? printed repeatedly display “R”, said the data is out of range.
