记录仪整机调试工作,在电路部份通电检查一切正常后,主要就是选择适当的桥路电阻来满足记录仪各道的起始值和电压常数值(电压常数是记录笔行程一大格所代表的输入电压值,通常称它为示值)。全烃道和热导道只要选好桥路电阻,起始值和示值就调好了,而烃组份道,由于“变比例点”的设置,就必须做更进一步的调整。一、什么是“变比例点”:记录仪烃组份道上有一个“变比例点”,位于记录纸刻度10mv。变比例点的左边属于1:1区,每一大格对应的信号是1mv;右边属于1:20区,
Logger 整机 commissioning work, the circuit part of the power to check everything is normal, the main choice is to select the appropriate bridge resistance to track the initial value of each channel and the voltage constant value (voltage constant is a stroke pen record Representative of the input voltage value, commonly referred to as the indication). Full hydrocarbon and hot runner as long as the selection of the bridge resistance, the initial value and the indication is adjusted, and hydrocarbon components Road, due to the “variable point” set, you must make further adjustments. First, what is the “variable point”: Logger hydrocarbon components on the road there is a “variable ratio point”, located in the recording paper scale 10mv. The left side of the proportional point belongs to 1: 1 area, the signal corresponding to each big grid is 1mv; the right belongs to 1:20 area,
