5、age) 47 Introduction The Heathkit Model IM-36 Transistor Tester is a professional quality instrument for shop, laboratory, or remote on-the-job testing of transistors and diodes. RadioFans.CN 收音机爱 好者资料库 Direct readings of DC Beta (gain) from 0 to 400 and accurate measurements of currents and leakage

6、 in transistors permit testing under simulated operating conditions. These conditions are set up by switch-selecting the voltages and currents that are applied to the transistor elements to duplicate published characteristics. Four lever switches permit eight different tests and measurements, which

7、result in a comparative quality figure (beta, gain) rather than the simple good-bad test made by many other transistor testers. The self-contained power supply, that consists of seven readily obtainable standard D- cell batteries, makes the instrument fully portable. Since no battery current is draw

8、n unless a transistor is being tested, long battery life is assured. External voltage sources for higher values of bias, collector, or leak voltages, can be connected to convenient binding posts for higher voltage transistor testing. Diodes can be tested for forward and reverse characteristics under

9、 appropriate current conditions. By following the step-by-step assembly, test, and operating instructions in the manual, you can build, test, and use this instrument in a few hours. The attractively styled cabinet, functionally designed control panel, and efficient circuitry, combine to give you a t

10、ransistor tester that you will use with confidence for many years. Refer to the Kit Builders Guide for complete information on unpacking, parts identification, tools, wiring, soldering, and step-by-step assembly procedures.
