美国GE公司氧传感器应用：1.用非危险性的低氧含量气体（例如：高纯氮气）吹扫取样系统。在正常工作时，要求通入传感器测试头的气体为500cc/min（1.0SCFH），压力为大气压。持续通入该气体，直到完成传感器的安装。2.在安装前，编程和校准的步骤。然后，调整4-20mA模拟输出，并将测氧的量程范围设置到0-25%O2。3.打开密封盒，取出氧传感器。为了保持氧传感器的能量，立即除去红色贴片，进行下一步。4.调整传感器，让它的金层电极对准变送器的底座上具有弹性的接触管脚。用手将传感器紧紧压在O2X1变送器上。5.此时对新传感器进行空气校准。在0-25%的氧量程范围时，正确的传感器校准会使变送器4-20mA的模拟输出端输出17.4mA的电流。6.用滚花螺母将校准过的传感器封装在变送器的测试头内，调整好变送器的位置，用手拧紧滚花螺母。7.模拟输出的读数应该开始下降，平衡时会达到较低的氧含量。此时，重新设置需要的量程范围。8.为O2X1供电。O2X1经过大约15秒钟的初始化后，三个LED指示灯会同时短时间地亮起。为了提高PPM传感器的测量精度，现在可以进行量程气校准。
