任何被测量的精确值是不知道的,总是大于或小于它的真值。甚至测量过程经过极大的改进后,还会存在微小的差异或不确定度。更好地了解误差的来源及其大小有助于准确的测量。一、电气测量电气仪表的准确度通常是指在某些参考条件下对某一特定值(例如满刻度值)的百分比。参考条
The exact value of any measurement is unknown and always greater or lesser than its true value. Even the measurement process has been greatly improved, there will be slight differences or uncertainties. A better understanding of the source and size of the error helps to make accurate measurements. First, the electrical measurements Accuracy of electrical instruments usually refers to the percentage under certain reference conditions for a particular value (such as full scale value).
