That sounds OK, if a bit low. Perhaps the resistors are large, or you might be diverting some current through a low(ish) impedance voltmeter, but those should be rare nowadays. The trick with diodes is that the curve is exponential - so for a "0.7V" diode, and pulling numbers out of the air, you can get 0.3V for nanoamp currents, or 1.0V for power-station currents (for the brief moment before it melts ;-) The real equation is very simple, if anyone wants to play. For instance, it's well explained here, midway down the page: http://www.allaboutcircuits.com/textbook/semiconductors/chpt-3/introduction-to-diodes-and-rectifiers/ http://www.allaboutcircuits.com/textbook/semiconductors/chpt...
