[Elecraft] Resistance checks - check your meter too!

[Bill Coleman N2BC]

Just did a quick scan of the K3 assembly manual - wonder how many downloads 
so far..?? !!     The following will likely apply to the K3 also - I'll find 
out next year for sure.

I'm at the end of day one of assembling my second K2, just finished the 
Control Board.  Used my trusty (old) auto ranging Fluke DMM to perform the 
resistance checks and went down the tubes on the 8V regulator output, 
measures 500 ohms - should the 3 to 4 Kohms.

To make a long story short....   be careful.  I did a simple test with the 
Fluke connected across a 3K resistor - my handheld DMM says the Fluke is 
applying almost 0.5V.  "Flipping" the meters, the handheld DMM only applies 
about 60mV - and the 8V bus resistance check is fine measured on the 
handheld DMM.

Clearly the Fluke's 1/2V is on the hairy edge of some of the active devices 
on the 8V bus.  It's interesting that the lead polarity makes no difference 
in the resistance measurement at all.

Now I'll carefully read the K3 assembly manual, then start the K2 front 
panel.  Hmmm... I wonder.  Nah, I'll still end up with a K2.
