一、前言电产电位差计的检定是热工仪表工作者的经常性工作。采用微型电子计算机代替人工检定,可减少大量的重复劳动。我们设计的系统能自动完成仪表上行和下行的指示误差检定工作,检定的上、下限范围任选。检定结果撒据指令可打印、绘图、存盘。在检定过程中还可随时查阅三种常用热电偶(镍铬——镍硅、铂铑——铂、镍铬——考铜)的刻度值。当仪表发生故障时,检定自动中断,发出警告,排除故障。系统的硬件配置为DOS3.3支持下的APPLEⅡc微机系统,外加12位A/D—D/A转换卡(模入为16通道,模出为1通道),该卡插2号槽。该系统适用于各种类型的电子电位差计。
First, the foreword Electroplate Potentiometer test is the work of thermal instrumentation workers. The use of micro-computer instead of manual testing, can reduce a lot of duplication of effort. We designed the system can automatically complete the instrumentation uplink and downlink error indication of the work of verification, the upper and lower limits of the optional. Test results sprinkle instruction can be printed, drawing, save. In the verification process can always refer to the three commonly used thermocouple (nickel-chromium - nickel silicon, platinum and rhodium - platinum, nickel chromium - test copper) scale value. When the instrument fails, the test automatically interrupted, issued a warning to troubleshoot. The hardware configuration of the system is APPLEⅡc microcomputer system supported by DOS3.3, plus 12-bit A / D-D / A conversion card (modeled as 16 channels, modeled as 1 channel). The system is suitable for all types of electronic potentiometer.
