一、指示表检定立现状随着科学技术的发展，电子式数字化并利用微机进行数据处理的计量仪器、装置得到广泛应用，并在逐步替代老式传统的纳机械式仪器。用于检定各类指示表示值误差的GU型光栅式指示表检定仪就是一例。指示表国家计量检定规程JJG34－1996明确规定，首先使用光栅
First, the instrument shows the status quo legislation With the development of science and technology, electronic digital and use of computer data processing instruments, devices are widely used, and are gradually replacing the old traditional nanomechanical instruments. An example of the GU type grating indicator calibrator used to test various types of indication error is shown. Indicator table JMetrics test procedures JJG34-1996 clearly stipulates that the first use of grating
