摘要
文中介绍了直流数字钳形电流表使用霍尔元件作为测量元件的原理以及霍尔元件的灵敏度、输入阻抗、输出阻抗受环境温度扰动的补偿方法。
This paper presents a tong type ammeter with DC digits involving the working principle of the Hall element used as a measuring element and describes a compensating technique for its sensitivity,input impedance and output impedance disturbed by the ambient temperature.
