When testing diodes, I plug them in to the test circiut on the
solderless breadboard. I then use my fingers surrounding the glass (and
avoiding the wires) there by testing them all at approx. 98 deg F. I do
the same matching transistors.
back to long term lurking and MSP430G2xx hardware/software . . .
