[Elecraft] K1 kit not showing resistance values at test points

[Don Wilhelm]

Andy,

Your "of" indication is a valid measurement - therefore it is a "reading"
It is a higher resistance than the range your meter is set to - switch 
to a higher range.
Once your range is above 100k, if it still indicates "of", you know that 
the resistance is greater than 100k, therefore all is well.

For the other points, do the same, increase the meter scale until you 
see a numeric indication on the meter, or if the range exceeds the 
expected resistance, and you are looking for a value greater than that 
listed, the test passes.

Often, you are asked to check the resistance of a point that has nothing 
connected to it - that can and should have infinite resistance.  The 
purpose of doing that test is to check for solder bridges or other 
shorted conditions.

For measurements like this, ohmmeters vary in how they display large 
resistances.

Please tell us which specific pins you are having trouble with.  Use the 
designators given in the manual and we can communicate unambiguously 
without guessing what you meant.
