個(gè)位高手，請(qǐng)教一下。三菱2AD模塊上有個(gè)偏置值和增益值。調(diào)教這兩個(gè)值有什么作用啊。不太明白啊。還請(qǐng)高手指點(diǎn)指點(diǎn)啊

偏置和增益的調(diào)整實(shí)際就是對(duì)模擬量與實(shí)際轉(zhuǎn)換數(shù)值之比的調(diào)整...2AD如果是電壓0-10V輸入時(shí),是不用調(diào)節(jié)的.0V對(duì)應(yīng)0,10v對(duì)應(yīng)4000,當(dāng)要選擇4-20mA電流輸入時(shí).4對(duì)應(yīng)0.,,20mA對(duì)應(yīng)4000.
