The Model 960 Semiconductor Tester, intended for Laboratory and Service applications, is specifically engineered to comprehensively test Low Power, Medium Power and Power Transistors. In addition, Model 960 includes flexible facilities for testing crystal diodes in direct comparison with diode manufacturers specifications. The Model 960 sequentially examines transistors for the following characteristics:- 1. Collector to Emitter and/or Base shorts» 2. Direct and comparative Icbo, in terms of Collector Current. 3. "Leakage" check (to be used for obtaining maximum accuracy in Transistor gain readings). 4. Direct reading Beta measurements (Gain).
