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:
 The primary winding of the current transformer should be connected in series with the current circuit under test. The secondary winding should be operated close to a short-circuit condition.
 The secondary circuit of the current transformer must not be open-circuited. Therefore, do not install a fuse in the secondary circuit.
