It measures skin conductance, which basically is perspiration rate. It's used in lie detector tests (which are not credible, by the way) as when your perspiration rate increases, so does your skin conductance.
Lie detectors use this to test if you're fibbing and I'm sure Scientologist use to to enhance their manipulation when they know you're talking about something that makes you uneasy.
I wandered into a Scientology center back around 2004 or so, they had left an e-reader sitting out.
It's an analog ohmmeter. The one I saw had fucking alligator clips attached to two tin cans to act as handles.
My day job at the time used multimeters, and one of them was an old analog meter. I played with it, and the e-reader. They're the same thing.
Yes, this is saying the same thing. The value of conductance is the inverse of resistance. Galvanic skin response uses the term conductance because you're measuring the presence of sweat, which conducts.
They've had various models over the years, but yes, they're all ohmmeters. Apparently, the current ones have updatable firmware for some reason, bringing us to OP.
