I would set up a properly grounded electrical distribution, not only for ESD purposes, but also for your safety. 50kohms seems awfully low. Mohms seems more typical. With a resistance of megohms they are perfectly safe to work on.
Thanks for the reply,
My house was built in the 60's so there is two wire through out the house. in the converted room I use for this stuff I have a few outlets that I have box grounded to a few 10' rods outside.
its the best I can do at this time. I have my oscilloscope hooked to one and my ham stuff to another.
As far as the mat goes, it has a black part that snaps onto one of the snaps of the mat. this has banana jacks to hook a wrist strap into and a wire to hook to the ground of a outlet.
being I dont have any grounded plug at that location I hooked it to the outside of a metal 4' 10 outlet bar at the bench.
If i remove the black thing from the snap and measure ohms between the snaps I get around 51K ohms if I resnap the black part to the mat and measure between the other snap and on of the jacks that a wrist strap plugs into I get 1M ohms. I assume there is a one meg resistor in the black housing.
The mat is two sided, a black bottom layer and a blue top layer. the metal snaps go thru both layers.
So Is the mat defective as it reads low ohms? or is it because the snaps short both layers?
