7.Typical Usages and Technical Parameters.
1) The parameters are listed in Table 1 while the sampling voltage is obtained
directly by using a resistor (as shown in Fig.1 below).
2) The parameters are listed in Table 2 while the sampling voltage is obtained
by using an IC (as shown in Fig.2 below).

8.Attention:
- The primary of the current transformer must be connected in series with the
loop of the measured current. The secondary should operate in a mode of near short
circuit.
- The secondary of the current transformer is not allowed to be open circuit,
Do Not install any fuse.
