A printed circuit board characteristic test set includes: a signal generator to provide a first signal; a sensor connected electrically to the signal generator to produce a mutual inductance effect with the inductor assembly and thus producing a second signal; a signal converter connected electrically to the sensor to convert the second signal into a DC signal and to measure a peak value voltage; a signal processor connected electrically to the signal converter to send a control signal corresponding to the peak voltage and a reference voltage; and a warner connected electrically to the signal processor. The warner is driven by the control signal and produces a warning signal when the conductor is short-circuited, and thus some voltage beyond the set value is measured. |
