该电感测试仪采用桥式电路结构，标准电感器和被试电感器作为桥式电路的两臂。当进行电感器电感值测量时，测试电压同时施加在标准电感器和被试电感器上，处理器通过传感器同采集流过两者的电流信号并进行处理后得被试电感器的电感值。

The inductance tester uses a bridge type circuit, a standard inductor and a trial inductor as the two arms of a bridge circuit. When inductor inductance is measured, the test voltage is applied to the standard inductor and the test inductor simultaneously. The processor can acquire the inductance value of the inductor through the sensor and collect the current signal flowing through both of them.

由于采用标准电感器、被试电感器同步采样技术，可不受电源电压波动的影响;加之测量过程是全自动进行的，避免了手动操作引起的误差，因此具有稳定性好、重复性好，准确可靠的特点。

Due to the use of standard inductors, subjects synchronous sampling inductor, not affected by fluctuations in power supply voltage; and the measurement process is fully automatic, manual operation to avoid the error caused by, therefore has good stability, good repeatability, accurate and reliable characteristics.
