摘要
文章主要介绍新型电场差分仪采集模块的实现方法。通过对四种频率的四道／二道、二次放电曲线的采集，采用自动调零、多次叠加、跟踪放大，来进一步提高测量精度，克服零漂、50Hz工频干扰。该方法在河南油田试验中，效果很好。
This article introduced the realization of sampling module in a new model of electrical field differential instrument. Through the sampling of four frequencies in 4/2 channels and in second discharge and by ap-plying automatic zero adjustment, multiple stackings and tracing amplifyirig, it further improved the mea-surement precision, overcame the zero drift and 50 Hz interference. This method has been proved in NAN-TANG oilfield testing and obtained a good result.
