An experiment research on changing the microampere meter to an ohm meter 微安表改装欧姆表实验的研究
Development of high accuracy microampere current sensor 高准确度微电流传感器的研制
Result 2 adult cases with promontory stimulation thresholds below 10 microampere and one prelingual deaf child show improved speech performance postoperatively. 结果2例成年人鼓岬刺激阈值在10μA以下,术后言语可懂度有不同程度的改善,一例幼儿术后言语可懂度有提高。
According to the system simulation, the implementing current in system is at the level of microampere, demonstrating that we have realized the object of circuits on low supply voltage with less power dissipation; 根据系统仿真,微安级的系统运行电流表明电路实现了低运行电压、低功耗的目的;
The direct-current leakage test is implemented by using the microampere shielded in low-voltage, and the leakage current increasing of generator stator winding abnormally is detected. 采用低压屏蔽法对发电机定子绕组进行直流泄漏试验,发现泄漏电流异常增大。
The measurement of high voltage current and microampere/ nanoampere are two important application directions in the field of current sensor, the two types of current are difficult to be tested directly, so the input signal must be processed and transformed before accurate measurement. 高压大电流和微纳安电流的测量是电流传感器领域中的两个重要应用方向,这两类电流信号难以直接测量,必须对其信号进行处理、变换才能达到精确测量的目的。
