    Transistor question,\

    I was reading on this site(Troubleshooting & Repair Guide)
    Section 5.1
    In the most general of terms, with any bipolar transistor (FETs and MOSFETs are completely different!), there should be about 600-700mV measured between the emitter and base

    Am I right in understanding one probe on emitter and one probe on base?

    Yes, basically the same as a diode junction. Polarity will depend on if the transistor is a PNP or NPN. Same thing from base to collector. Collector to emitter will read as open.
