Product Overview：

Test the leakage current, current, transformation ratio, ratio error, angle error, phase, polarity and phase sequence of the
primary and secondary circuit of the current transformer in the 380V/220V distribution system.


Main Features: ​ 

1. Current clamp adopts high performance Permalloy core, magnetic shield and CT digital integrated technology, with strong anti-interference ability, high accuracy for testing.
2. The primary flexible current clamp is especially suitable for small space and flat cable dense places, more convenient and fast for testing.
3. ETCR9620B primary current clamp adopts wireless transmission, more convenient for testing.
4. Data hold function, data storage function.
