在测量技术中,为了达到准确一致的测量,一般采用以下五种方法和手段。 (1) 标准仪器或标准装置这是用准确度高于被检仪器3～5倍的标准仪器或标准装置直接检定(或校准)被检仪器,这也是长度、电磁、容量等物理量量值传递所采用的有效方法。但该方法需要在计量部门进行检定,极为不便。
In the measurement technology, in order to achieve accurate and consistent measurement, the following five methods are generally used. (1) Standard instrument or standard instrument This is to test (or calibrate) the tested instrument directly with the standard instrument or standard device whose accuracy is 3 ~ 5 times higher than that of the tested instrument, which is also the transmission of the physical quantity such as length, electromagnetic and capacity The effective method used. However, this method requires verification in the metrology department and is extremely inconvenient.
