The article seems to believe the church is using a legal sub-corporation to protect the Church's "E-Meter" device which is some sort of mumbo jumbo dousing rod sort of thing they use in their auditing (ritual?)
Right to repair is never a bad thing and it's unfortunate that all these bad actors are fighting it to protect their interests
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.
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.
