  Ed,

The first two readings are very likely OK, you might re-check by 
reversing the leads or putting new batteries in your DMM.  The other 
possibility is that you are using auto-ranging, and the reading may be a 
bit different if you switch to the first fixed range greater than 90k

I don't know how you DMM indicates an infinite reading, but you can 
easily check - it will be the same reading as you get with nothing 
connected to the leads.
