[GreenKeys] Panel meters and such.

[Ralph Mowery]

You are correct Jeff.  The data sheets only show what it should be, not what
it might actually be.  I have ran into factory new items that are marked one
thing, but have been another value, or even the wires are backwards.  

I used to have a hard time at work.  Most of the time I was trouble shooting
electrical/electronic problems.  The equipment had been running and then the
problem came up.  About every 3 or 4 years  there would be a construction
project and I would have to check it out.  Took me a while each time to get
it in my mind not to trust anything in that new equipment.

Just one other thought that came to mind, that is a 100 mili and not 100
micro amp meter ?
