BK 520B Transistor Tester

Features:

    -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.
