dear Colin
The reason for 100mA is so that continuity of earth screening (functional Earth) can be tested as well as PAT testing on IT equipment. 100mA is not part of a medical standard (as is a 1010 body model) but merely an additional low current option for those interested in using less than 1A.
With regards to wetting contacts and having probelsm with 1A on Fluke products, Rigel / Seaward have presented a paper at the June IPEM seminar which might answer most questions / comments riased in this briefing. Anybody interested in further information, please contact me.
