The Chipmaster Compact is a hand-held IC tester, capable of identifying and testing digital ICs with up to 40 pins. Unmarked and house-coded devices can be quickly and accurately identified, together with possible functional equivalents for replacement. The tester can operate in either conditional or unconditional loop modes, enabling simple detection of intermittent or temperature related faults. The clear 2x16 dot matrix display provides diagnostic information down to individual component pins. No programming is required, and the tester is powered by 4 AA size batteries (included).
