I've just measured my a/s mat. I used two small metal boxes about 4" x 2", spaced 3". I applied 13V thru my DMM and pressed fairly hard (thru' good insulation!) to get 0.2uA, giving a value of 65Mohm. RH here is probably 60% or more. Pressing lightly gives 0.1uA, the smallest the DMM indicates. I think this is probably OK.
The mat is Maplin N74CR. It's £14.99 http://www.maplin.co.uk/large-anti-static-mat-99068 Graham On 19:59, Ian White GM3SEK wrote: > Alan Bloom wrote: >> I agree with all Ian's comments except: >> >>> Almost any ani-static mat and wrist strap will be OK >> >> My testing has shown that not all anti-static mats are created equal. >> In particular, the Radio Shack portable mat P/N 276-2370 has much too >> high a resistance to be effective.
