Ok, I spent an hour -- yes, an hour, no exaggeration, a literal hour (ok, 4 minutes of exaggeration, it was 56 minutes, not an hour) -- on the phone with this fool today. Our instruments are designed to do repeated readings on a green tile (which we provide) within .3 units on each axis of the XYZ color scale (those in printing and computer images or web design will at least have a faint grasp of that scale. So, if the factory reading on the X of a green tile is 13.61, than the instrument the tile belongs to is within specifications so long as the reading is between 13.31 and 13.91. That's how it's designed. ANd it's pretty good. (though we have two models that will read within .15 units, which is REALLY tight...). So this guy argued with me for an hour about how our representative broke his machine the other day when he came to do scheduled cleanign and calibration verification. Basically, it wasn't with .09 units anymore, so it must be broken. I explained that it wasn't designed to be that precise. It will be impossible FORCE it to be that precise. but no, apparently we broke it. We should pay to fly someone to his facillity and fix the machine. No cost to the customer, obviously. Idiot. Anyway, this rant entirely ignores that he's reading it in a different color scale anyway and so his numbers which he thinks are even farther off are completely erroneous.
So, translation to IS terms: The question was essentially: why won't my 56k flex modem download as fast as a DSL cable?
In layman terms, it was essentially: Why won't my toaster make pizza?
(it's a good job, but this guy was a major wanker, so I had to rant).
