该仪器是一种单一的、高增益运算放大器,放大器是一种带有单块前端的半导体。功能微型组件作为一种超低偏压场效应转位器。应用二个镶嵌在面板上的数字读出器,一个用于电位差读出器,另一个用于零位电流监视。荧光面板上(使容易观察)用七条以浮动小数点进行读出,可达±0.1％的精确度和3次/秒的取样率。采用二组模块的直流电源,供给运算放大器所要求的二个±15伏电压和100毫安电流。图1为监视器线路完整示意图。装在有机玻璃壳体内的四个选择开关中的任意一个可对运算放大器的输入进行选择,均可允许监视电位差。选择器
The instrument is a single, high-gain operational amplifier, an amplifier with a single front-end semiconductor. Functional miniature components act as an ultra-low bias field effect transposer. Two digitally mounted digital readers are used, one for the potential difference reader and the other for the zero-current monitor. Fluorescent panels (for easy viewing) are read with seven floating-point decimals for ± 0.1% accuracy and a sampling rate of 3 times / second. Two modules of DC power supply are used to supply two ± 15 volts and 100 milliamps of current required by the op amp. Figure 1 shows a complete schematic of the monitor line. Any one of the four selector switches mounted in the plexiglass case allows selection of the op amp's input, allowing monitoring of potential differences. Selector
