7. Performance Parameters:

Performance parameters when applied as shown in Figure 3 are listed in the table below: 

8. Attention:

① Connect the primary winding of the current transformer in series in the circuit under test. Operate the secondary winding approximately in a short-circuit state.

② Do not allow the secondary circuit of the current transformer to be open-circuited. Do not install any fuses in the secondary circuit.
