传感器如何进行无源校准及两点特别说明a)首先读出变送器内部设置的4mA压力值和20mA压力值，看是否与实际的4mA压力值和20mA压力值相一致，若一致，则直接更改4mA压力值和20mA压力值到量程迁移后的压力值即可。 b)如果变送器内部设置的4mA压力值和20mA压力值，与实际的4mA压力值和20mA压力值不一致，可先把实际的4mA压力值和20mA压力值折算到变送器内部设置的4mA压力值和20mA压力值，再折算量程迁移后的压力值，将折算值更改到4mA压力值和20mA压力值便可。例如：假设一台变送器量程为-10bar－50bar，想将量程迁移到10bar-40bar，读出变送器内部设置的4mA 压力值和20mA压力假设为0-10Kpa,进行如下折算：－10bar 和0相对应,50bar和10Kpa相对应，通过计算，可以计算出折算方程为：P折＝P实/6＋10/6("P折"为折算后的压力值，"P实"为实际压力值）,由此方程可计算出折算后4mA压力值应为：10/6+10/6=3.333KPa,折算后20mA的压力值应为：40/6+10/6=8.333KPa, 于是可以通过组态软件将变送器内部的4mA压力值设置为3.333,将20mA压力值设置为8.333便可。特别说明： 1）量程迁移只能在原量程范围内迁移，若迁移超出原量程范围，则变送器的线性度变会变差。 2）进行无源校准时，量程迁移不可过大，迁移比最好不要大于3:1，过大会造成变送器输出不稳定，而且分辨率较低。大迁移比量程迁移在要先进行增益设置，再进行输入压力校准。
