"Repairing" as in "noticing they don't actually do anything beside measuring resistance like any common multimeter from the DIY shop"

Do they even measure resistance? Hold the probes on a multimeter. Tell me how much resistance you're measuring. With my MM I'm registering microohms.

That just goes to show how important proper training is. Without the right scientology certifications you have no idea how many evil alien ghosts living in your soul those microohms indicate!

... Do you mean you're measuring megaohms (M) across your body? Or microohms (u) between probes directly? Or milliohms (m)?

I've wet my finger and measured like 30kOhms across a half inch of skin or so. And if you get into your bloodstream, the salty liquid has very low resistance BUT BUT BUT this will kill you if the probe paths across your heart

When I first read about this stuff, it said they were just really sensitive EKG machines. Literally just measuring your pulse.
