【摘要】 本文介绍一种用微机对电子电位差计进行自动检定的系统。该系统利用计算机控制Ｄ／Ａ转换器及精密电阻分压器，输出标准电势作为被检仪表的信号源；同时在仪表的指示机构中附加一指针位移读数传感器，示值位置通过Ａ／Ｄ转换器输入计算机进行检定结果的数据处理及打印输出等。更多还原

【Abstract】 An auto-calibrating system design for electronic potential Difference Meter is proposed in this paper.In the system, a computer is applied to adjust a D/A device and a precise voltage divider for criterion signal output.The meter reading is obtained by a special displacement transducerinstalled in display mechanism.With an A/D converter,the calibrating data can be dealt with by the computer.The calibrating result can be displayed and typed.更多还原
