[Elecraft] K2, resistance check Q7

[Erik Linder]

Hi again and welcome to the series "Get to know your DMM".
This week well learn how to use the setting "Auto" and "Manual".
:-)

I found out just now that my DMM shows different readings in "auto" and 
in "Manual".
If I set the DMM to Manual and kohm i get the correct reading of 2.7 
kohm. But if I set it at auto I get 760 ohm...

It must be different values of voltage the DMM uses to measure in auto 
and manual.

OK, case closed.
I will proceed with alignement in step III

Sorry for the noice on the list....
