[Elecraft] ESD mat measurements

[Lyle Johnson]

Here's some more information for the latest swirling controversy :-)

If you try to measure the resistance of an anti-static mat, you'll need 
an ohmmeter good to at least 1,000 megohms.  Even my HP/Agilent 34401A 6 
digit benchtop DMM can't measure that high!

Why is the resistance so high if it is supposed to dissipate static?

If you are convinced you need to measure yours, here is a place that 
sells test equipment for doing just that <
