Wow!
I have just returned following a motoring accident which put me out of action to find my post has sparked off quite a debate.
Thanks to you all.
In summary < 1A tests should not be required due to manufactuing standards such as 601 etc and are unlikely to make use of solid state devices which may be damaged by this test. RTFM just in case!
So, dare I ask which tester seems to be the best. Metron, Rigel or Biomedical?
Kind regards
