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 adopts the bridge circuit structure, the standard inductor and the tested inductor as the two arms of the bridge circuit. When the inductor inductance measurement, test voltage applied at the same time in the standard inductor and the participants inductors, processor by sensors with current through the two collected signals and processing must be tried after inductance value of the inductor. 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。 It is not affected by the fluctuation of power supply due to the use of standard inductor and the test inductor synchronous sampling technology. In addition, the measurement process is fully automatic, avoiding the error caused by manual operation, so it has the characteristics of good stability, good repeatability and accurate and reliable.
