1.[High quality]The transistor tester made of high-quality materials, , good performance, long life, using 1 ¡ã metal film resistance, more . 2.[Practical]The tester has a digital display that can be clearly displayed, which is more convenient for your use, and can automatically detect the pin layout of the detected parts, which is economical and practical. 3.[Advantage]The test time of the capacitance tester is about two seconds. Only capacity or inductance measurements can extend the cycle. Only one measurement is needed to find the connection of the rectifier bridge. 4.[Wide Use]The capacitor tester can be used to measure the current amplification factor of bipolar transistors and the voltage threshold of the base emitter. It is suitable for NPN and PNP bipolar transistors, N and P channel MOSFETs, diodes, unidirectional and bidirectional thyristors.
