1. The inductance measuring instrument has a simple and practical sorting function. The parameter setting of this function is simple and easy, and the results are displayed intuitively, which can meet the requirements of people's using units for incoming inspection and rapid sorting and measurement of inductance production lines.
 2. The inductance tester adopts the bridge circuit structure, and the standard inductor and the tested inductor are the two arms of the bridge circuit.
 3. When measuring the inductance value of the inductor, the test voltage is applied to the standard inductor and the tested inductor at the same time, and the processor collects the current signals flowing through both through the sensor and processes them to obtain the inductance value of the tested inductor.
 4. Due to the synchronous sampling technology of standard inductor and tested inductor, it is not affected by the fluctuation of power supply voltage; In addition, the measurement process is fully automatic, avoiding errors caused by manual operation, so it has the characteristics of good stability, good repeatability, accuracy and reliability.
