ATM Another question about the foucault test................

[John Murray <imasloth@bigpond.com>]

Morning All,
	I noticed something this morning which seems a bit odd. I've done a few
sets now of the k/edge test and generally I notice after the first set that
I get tired? or whatever and am unable to make decent judgements as the
knife edge is moving and the zones are nulling. This morning I was quite
tired and weary after a 12 hr night shift and yet I was able to do two tests
straight off with less variation in the readings. It also seemed easier to
pick up the nulling in the zones. Perhaps the secret with this test is to be
really knackered when doing it! Is this a good way or should I just put the
readings down to a fluke. How do others find it?

Cheers
