● Notes:
a. In practical applications, the sampling resistance should be less than or equal to the rated value given in the above table, which will improve the nonlinearity and phase shift;
b. If the conversion ratio required by the user is different from the above, it can be customized according to the user's requirements.
8. Attention:
① The primary of the current transformer should be connected in series with the current circuit under test, and the secondary should operate in approximate short-circuit mode;
② The secondary circuit of the current transformer must not be allowed to open circuit during operation, so please do not install any fuse.
