audioguru Posted January 13, 2006 Report Share Posted January 13, 2006 Hi Leo,My multimeter has a Diode Test function where it outputs a small current then shows the voltage. A darlington's forward-biased base-emitter would show about 1.2V. Reverse biased would show max volts. Forward-biased base to collector would show about 0.6V. Reverse-biased would show max volts. Forward or reverse-biased collector to emitter would show max volts. Max volts means no current flows.The darlinton transistor tested this way must not be connected to a circuit.
