具有零点迁移的仪表,如DDZ-Ⅲ型电动单元组合仪表,零点和满度的调校,相互牵制较大.因此,为了能尽快调校,往往通过对一个调校点适当超调,然后调校另一点补偿其超调量.这种方法通常是定性估调,调试结果的好坏取决于调试人员的经验水平.本文介绍一种定量的调校方法,这种方法不仅调校快,且易为初级调试人员所掌握.1.基本原理我们仅讨论负迁移情况.设仪表输入、输出满足
With zero-point movement of the instrument, such as DDZ-Ⅲ-type electric unit instrument, zero and full adjustment, mutual contain larger, so in order to be adjusted as soon as possible, often by adjusting a tuning point appropriate overshoot, and then tune Another point to compensate for the school overshoot This method is usually qualitative estimates, the results of the debugging depends on the level of experience of the commissioning staff.This article describes a quantitative calibration method, this method not only fast calibration, and Easy for the primary commissioning personnel to master .1 basic principles we only discuss the case of negative migration set the meter input and output meet
