问电子平衡电桥与电子电位差计在调校方法上有什么不同?答这个问题提得很实际。长期从事仪表调校的同志都有很深的体会;电子平衡电桥调校困难,不象电子电位差计那样的简单。问题的症结在于过去都是采用 R_1(零点调整电阻)和 R_2(量程调整电阻)轮流重复多次的调整 Asked the electronic balance bridge and electronic potentiometer calibration method in the school What is the difference? A: This question is very practical. Engaged in instrumentation have long been gay comrades have deep experience; electronic balance bridge calibration difficulties, unlike the electronic potentiometer as simple. The crux of the problem is that in the past all the adjustments were made using R_1 (zero adjustment resistor) and R_2 (range adjustment resistor)
