POLAR INSTRUMENTS GRS200 fault locator system is based on proven Analog-Signature-Analysis, comparing the nodal impedance between an unpowered known good board and a faulty pcb. Unit allows to find typical production faults in electronics manufacturing, as well as defective components in service & repair without detailed circuit knowledge. Product consists of the analog-signature-hardware and powerful software with LIVE signature analysis, program mode, CAD data viewer, schematic diagrams and the optional digital multimeter interface. This makes it easy to locate missing, reversed or even counterfeit components. In addition, wrong component values or component types are diagnosed, as well as possible shorts or interruptions. The central information element here is the CAD data of the pcb.
