[Elecraft] ESD Protection for K3 Assembly

[Ron D'Eau Claire]

Since it has an alligator clip, connect it to the mains safety ground. Also
connect the mat to the same ground.

DO NOT attach the alligator clip to the edge of the mat. If there's a
terminal for the ground, fine, but the resistance of most mats is too high
to simply clamp an alligator clip onto the side. 

You should find that there is about 1 megohm of resistance between the metal
terminal that rests against your wrist and the alligator clip at the end of
the cord. That is a built-in resistance designed to protect you from
dangerous electrical shock should you touch a "hot" circuit, but still low
enough to ensure that any charge on your body is dissipated rapidly --
provided the alligator clip is attached to a ground.

73, and have fun! Ron AC7AC

Jay most have a snap on them that snaps to the one on the mat like it. Then
the mat attaches to the ground.

Hi all,
 
I received my K3 kit yesterday and am setting up to start assembly. I bought
an ESD mat and a wrist band. I was wondering what I should connect the
alligator clip from the wrist band to, for best protection?
 
Thanks,
 
Jay (KD6AMA)
