The main objective of this article is to know about scr component analyzer. The word SCR stands for Silicon Controlled Rectifier. These three terminal devices can be hardened by a numeral of dissimilar methods. The more ordinary methods utilize a DVM or an Analog Meter. Typically the SCR is hardened by merely looking for the lack of conduction among Anode and Cathode leads. A high resistance would indicate a functional device, given the limitations of not gating the device.
