1. When the measured current direction is consistent with the direction marked on the sensor, the sensor output ISN is positive.
2. The secondary side connection line of the product is preferably a shielded line. The shielding layer is close to the product end and the connection line can be connected to the case, and the negative power supply or power supply 0V.
3. The verticality requirements for the mounting screw holes of the power sensor: it is required to be level 8 or above (or below 0.06) in the national standard.
4. The flatness requirements for the installation surface of the power sensor:
(a). The flatness of the large plane installation is national standard 11 or above (or the flatness is less than 0.25mm);
(b). The flatness of the installation surface is designed with small round bosses It is required to reach the national standard level 12 or above (or the plane fluctuation is less than 0.5mm);
5. No tolerance ±1mm is noted;
