4、打开温度采集软件的实时数据界面，即可看到9个温度传感器所测量的温度数据，也可打开曲线输出界面对温度变化曲线进行查看，此时可根据显示温度来调节工业高频炉6、工业恒温炉13、热轧辊20的温度，以满足不同材质的带状无油润滑轴承28对温度的要求。4. Open the real-time data interface of the temperature acquisition software, you can see the temperature data measured by 9 temperature sensors, and you can also open the curve output interface to view the temperature change curve. At this time, the industrial high-frequency furnace can be adjusted according to the displayed temperature. 6. The temperature of the industrialconstant temperature furnace 13 and the hot roller 20 is to meet the temperature requirements of the belt-shaped oil-freelubricated bearings 28 of different materials.

温度采集软件中的报表输出截面用于输出相应的Excel文档对温度进行记录，并可方便历史温度的查看及打印；软件中的数据存储界面，可用于选择9个传感器中单独的一个进行数据的放大查看与存储，可得到更加精准的温度数据；最后关闭时，可按照上述步骤1-4逆向操作进行。The report output section in the temperature acquisition software is used to output the corresponding Excel document to record the temperature, and it is convenient to view and print the historical temperature; the data storage interface in the software can be used to select a single one of the 9 sensors for data recording. Enlarging, viewing and storing, you can get more accurate temperature data; when closing, you can reverse the operation according to the above steps 1-4.
