直流数字电压表在测量过程中的统计控制

Statistical Control of DC Digital Voltmeter in Measurement Process

在测量过程中来源于异常原因引起的波动是非正常现象,是必须避免的。那么我们如何避免这一现象便成为重中之重。判断一个测量过程是否处于正常状态,运用统计技术的控制图方法是核心。本文以直流数字电压表为例,选取1V的点作为试验对象,取得试验数据建立分析用控制图,并最终将其转化为控制用控制图。

Fluctuations caused by abnormal causes in the measurement process are abnormal and must be avoided. Then how we avoid this phenomenon has become the top priority. To determine whether a measurement process is in a normal state, the control chart method using statistical techniques is the core. In this paper, DC digital voltmeter, for example, select the point of IV as the test object, to obtain experimental data to establish the analysis of control charts, and finally into the control chart.
