This video shows my initial impressions of a low-priced IC Tester that I bought on eBay. The tester is supposed to identify and evaluate logic ICs in the 7400 series, 4000 series, 4500/14500 series, plus Op-Amps, bipolar and MOS transistors, Zener diodes, opto-couplers, small SCRs, and a few other devices. But the documentation is poor and not very comprehensive, so it was not clear exactly WHAT it would test, HOW it would do it, and how WELL it would do it. So I tried a number of short experiments to 'wring out' the tester and get a better feel for what it could do, and how useful it would actually be in my lab.
