This technology uses AC positive excitation, which can test the characteristic curve of the current corresponding to the voltage of the component in the power-off state, and can display it on the display screen. Because each component has its own specific curve, when the component fails, the curve also changes. Therefore, using the VI curve tester to analyze the curve of the component can diagnose the fault.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eMain Functions of VI Curve Tester:\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"color: #666666; font-family: verdana, Helvetica, Geneva, Arial, sans-serif; font-size: 12px; font-style: normal; font-weight: 400; background-color: #ffffff; display: inline !important; float: none;\"\u003e2.
