PC-controlled semiconductor tester (1):

This versatile, PCcontrolled, test instrument, designed and marketed as a kit by ELV, puts you in a position to view, on your PC monitor, the curves that describe the main electrical characteristics of transistors, LEDs, zener diodes, triacs and thyristors. These curves, like no other test on these devices, provide a definitive goodlfaulty indication and in addition can help you decide whether or not a discrete semiconductor is sultabie for a particular application.
