BK 520C Industrial Transistor Tester The B+K Precision model 520C Transistor Tester is designed for in-circuit and out-of circuit transistor testing with special features for making additional tests on devices out-of circuit. The instrument is designed for a minimum amount of control manipulation. Making for rapid testing of most devices.
Determines good or bad transistors. FET"s. SCR"s. or diodes. Patented limited-energy pulse circuit permits in-circuit testing in the presence of low shunt impedance"s with complete safety for the device under test.
