| Abstract: | In order to realize the accurate measurement of inductance in different frequencies, an improved voltage vector ratio method based on synchronous sampling is proposed. Synchronous data acquisition is realized by NI-5922, and the automatic measurement system is designed by using component oriented technology of LabVIEW. The system can precisely measure inductance with accuracy up to 0.01% in the range of 1H at different frequency. The measurement principle, the achievement of synchronous data acquisition and data processing are discussed. This measuring system can also be used to quickly measure any kinds of AC impedance. |
