Used QT2 diode tester transistor transistor characteristics meter analyzer

QT2 transistor curve tracers can be measured according to the semiconductor diodes, transistors and low-frequency dc parameters. Maximum collector current of up to 50A, basically meet the test of the semiconductor tube 500W or less. With high-pressure testing capabilities, can 3KV (5KV) \ Semiconductor tube below the breakdown voltage and reverse leakage current test, the test current maximum sensitivity can reach 0.5uA / degree. Base ladder ladder has a pulse output signal, measurable secondary breakdown characteristics.
