一、前言在检定0.2级或0.5级精密指针电流表、电压表和功率表时,由于检定数据多、数据处理和修约繁琐且容易出错,占了大量时间。怎样才能节省检定时间并提高效率,真正做到高效、准确呢?一种途径是用设备自动控制软件和图像处理的方法实现全自动检定,但成本非常高。考虑到成本和准确度,笔者向大家介绍一种电三表半自动示值误差检定方法。
I. Introduction In the test of 0.2 or 0.5 precision pointer ammeter, voltmeter and power meter, due to the test data, data processing and repair about cumbersome and error-prone, accounting for a lot of time. How to save test time and improve efficiency, truly efficient and accurate? One approach is to use automatic device control software and image processing methods to achieve fully automatic verification, but the cost is very high. Taking into account the cost and accuracy, I introduce to you a three meter semi-automatic error indication method.
