The invention relates to a device for avoiding and instructing fraudulent use, in particular to a power-stealing resistance load management terminal, comprising a power-stealing detection device which includes a choosing unit, a signal acquisition unit, a detection unit, an analog-to-digital conversion unit, a comparison unit, a frequency generator, a signal coupling unit and a signal processing unit. The power-stealing resistance load management terminal collects and detects the harmonic signal of each detection unit in a current circuit in real time, chooses the harmonic signal with smallest amplitude, and uses the frequency of the harmonic signal with smallest amplitude as the frequency of the detection signal, so the chosen detection signal actively avoids the harmonic signal with large interference. The device overcomes the shortcoming of the prior art that only fixed-frequency disturbance signals can be sent out. Simutaneously, the power-stealing resistance load management terminal can detect various power-stealing happenings that the current circuit is opened and short cut, or a lalrge transformation ratio current transformer is replaced; and the power-stealing resistance load management terminal is a comprehensive power-stealing resistance load management terminal.
