A baffling experience was recorded today 

Using a multimeter where you have to select the range the resistance of a forward biased diode was about 3.3 Mohm and infinite reverse biased
Then using the diode function the typical forward voltage drop was obtained without incident.

So what's the beef  well the auto ranging multimeter showed infinite resistance when forward biased and a few megohm when reverse biased  (and it has no diode test function)

I went back and rechecked all my results and even added a couple other multimeters to the mix

Gonna have to think about this one for a while

Set the Ideal or the Centech to measure DC volts.
Check the polarity (and voltage) of the DC being put out by the Amprobe's when they are set to ohms or diode check functions.
