近几年来,由于电子技术和集成电路制造技术的发展,国际上出现了多种数显卡尺。其中容栅式数显卡尺具有耗电省、抗干扰能力强等优点,得到越来越广泛地应用。它直接显示测量数值,避免刻线卡尺人为的视觉误差,分辨率高,通常为0.01mm,精度与机械式千分尺相当。此外还具有在测量范围内任意位置置零、公英制直接换算以及与打印机或计算机连接,把测量数据送入打印机或计算机进行数据处理等功能。它是刻线卡尺的升级换代产
In recent years, due to the development of electronic technology and integrated circuit manufacturing technology, there are many kinds of digital calipers in the world. Including capacitive digital calipers with power saving, anti-interference ability, etc., has been more widely used. It directly displays the measured values, to avoid the artificial caliper error, high resolution, usually 0.01mm, accuracy and mechanical micrometer quite. In addition, it also has the function of setting zero at any position within the measurement range, converting directly to the metric system and connecting with a printer or a computer, and sending the measured data to a printer or a computer for data processing. It is the engraving caliper upgrade generation
