SUMMARY

hFE on a multimeter refers to the forward current gain of a bipolar junction transistor (BJT). This measurement is crucial for small signal analysis and is easily obtained using a dedicated socket on the multimeter. Understanding hFE is essential for analyzing transistor performance in hybrid models of two-port transistor circuits. It is one of the key parameters that influence the behavior of transistors in electronic applications.

It is an option on the multimeter, I have read a little bit saying it has to do with transistors and it is a "test" for it...

Yeah, it has something to do with current gain in transistors, but I don't remember the details. I'm sure someone here will jump in with a solid answer.
 
hFE is the forward current gain of the bipolar junction transistor. There should be a socket or something on your multimeter to plug in the transistor.
