This should be based on manufacturer's data, but here is my $0.02 worth of knowledge:
- Wristwatch: on the order of ~1 MOhms, checkable with a DVM. This is a preferred value, as too low may cause damage to devices or may tingle people (what you really are looking is a path to drain the charge)
- Mat: this should be Ohms/square, again based on manufacturer's data, on the order of ~kOhms/square
CECC 00015 do a google..
1MOhm to 35M is ok for working on none live apparatus 10M to 35M for live working (upto 500V AC) as far as I believe..In most cases the 35M upper limit is too high for most multimeters.
