Mark,

If you had infinite readings on those that you marked 'XX', then they 
too are OK.
Note the '>' symbol before the number - it means 'greater than', and 
infinity is greater than 100k ohms.

The readings listed have to cover all meters and circumstances.  An 
ohmmeter on a high resistance scale may respond to just your fingers 
across the probes, so it would be counterproductive to write a reading 
of 'infinity' in the manual - while '>100k' will cover most all meter 
situations while still revealing a short somewhere.

73,
