一、前言 H.F.580视频显示测量装置是英国Hartridge公司八十年代的产品,它专与喷油泵试验台配套对喷油泵进行参数测量及校准。我们在使用的基础上,根据观察、分析,在无任何制造技术资料(只有一份使用说明书)的情况下进行了整机电路、计算机接口电路、微型计算机汇编程序(Z80汇编语言)的研究,取得了一定的进展。本文的目的是:一般介绍H.F.580视频显示测量装置,重点介绍我们研究的“量程坐标值(第一象限)的自动变换”方法。
I. Foreword H.F.580 video display measuring device is the British company Hartridge eighties products, it specifically with the injection pump test bed supporting the fuel injection pump parameter measurement and calibration. On the basis of our use, based on the observation, analysis and research of the complete machine circuit, the computer interface circuit and the microcomputer compilation program (Z80 assembly language) without any technical data (only one manual) Some progress has been made. The purpose of this paper is to: General introduction H.F. 580 video display measuring device, focusing on our study of “automatic calibration of the first quadrant” method.
