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.
