ELECTRIC TESTING DEVICE AND ELECTRIC TESTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an electric testing device that firstly determines whether or not a tested device is already surely connected to a jig before executing procedures for an interlayer pressure test and is capable of reducing a phenomenon of spark discharge.SOLUTION: An electric testing device according to an embodiment of the invention comprises: a resonant circuit module to be coupled with a tested device; a first power supply module that includes a first switch element and provides first voltage to the resonant circuit module when the first switch element is in an off state; a second power supply module that provides second voltage to the resonant circuit module when the first switch element is in an on state; a measurement module that measures an electric signal generated at least when the resonant circuit module receives the first voltage; and a control module that controls the on or off state of the first switch element on the basis of the electric signal. Therefore, the electric testing device can have functions of open circuit check and inductance measurement.
