Simplify the system structure, directly output standard small signal without secondary conversion, directly input secondary equipment through A/D conversion, reducing the source of errors;
The magnetic core has high permeability and low temperature drift. In the temperature range of -40℃～+70℃, especially at -40℃, the variation of the error meets the standard requirements
The output internal resistance is small, which overcomes the error caused by the cable and can be adapted to various cables;
The composite film capacitor with CVT transformer structure has good long-term stability;
The accuracy changes little due to the influence of ambient temperature.
