That's correct, AFAIK.

Though I have seen the short bit of film that shows the factory procedure, 
I do not know the answer to your question. I would assume that the 
measuring device would have placed a load on the output, but I hate to 
assume anything about this stuff. There is much more extensive footage of 
these procedures, I'm told, and eventually it will be released on DVD, I'm 
also told. We can only wait and watch.
