[Elecraft] KX1 Newby Help!

[Don Wilhelm]

Burke,

What do you mean by "nothing"?  I am going to guess that it means the 
DMM indicates the same as when you have nothing connected to the leads 
and the DMM is set to read resistance (correct me if I am wrong).

If my assumption (guess) is correct, that is the indication for infinite 
resistance (i.e. an open circuit) for your DMM.

Now - consider the meaning of the ">" indicator.  That is the symbol for 
"greater than".  Infinite resistance *is* greater than the value 
indicated, so if my assumption is correct, you have no problem.

A DMM resistance reading that continues to climb usually indicates that 
the DMM current is charging a large capacitor.  As long as the lowest 
reading is greater than that indicated in the manual, no problem exists.

Realize that at this point the resistance measurements are checking for 
shorts.(with the exceptions of the readings that are < (less than) 5k), 
so any measurement that is greater than the indicated value (to include 
infinite resistance = open circuit) passes the test.
