AI Technical Summary

Technical Problem

The existing ammeter housing for current detection lacks auxiliary calibration function, which can easily lead to increased measurement errors when using position deviation and reduce measurement accuracy.

Method used

An ammeter for micro current detection with an auxiliary calibration device is designed, including a support base, a moving mechanism, a positioning mechanism and a calibration mechanism. The calibration mechanism can drive the arc plate to flip through the cooperation of the tooth plate and the flat gear, achieving auxiliary calibration of the ammeter body.

Benefits of technology

Through the auxiliary calibration function, the measurement error of the ammeter is reduced, the measurement accuracy is improved, and the ammeter can respond to current changes more quickly and accurately, improving working efficiency.
