BK Precision 520C - Industrial Semiconductor Tester with Leakage Test
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.
Easy to operate panel eliminates the need to refer to a reference or operating manual only three switches, no panel adjustments.
Six position test switch makes it unnecessary to know the device terminal identification.
A logarithmically scaled meter identifies leakage in both Silicon and Germanium devices.
Front Panel socket for out of circuit transistor testing.
