The GM328A test components and shows the test results on the clear digital
LCD screen. This tester automatically detects if a NPN/PNP transistor, FET, diode, dual diode, thyristor or SCR is connected and has an automatic identification of the pinout of the components.
With NPN and PNP transistors the common-emitter current gain factor and emitter threshold voltage from the emitter leakage current are measured.
Furthermore, there is support for 2 resistance measurements that represent the positive and negative on-state voltage. From an FET, the
gate threshold voltage and gate capacity are measured. This tester can also be used as a signal generator and frequency meter.
The tester comes with a transparent case that has yet to be put together. (This case can slightly differ from the pictures)
Attention! There is no adapter included with this product. A 9V battery can also be used with this cable.
