content: Hi all, another newbie here drawn in by the super entertaining and amazing videos on youtube GREAT JOB thank you for those!!!!!I`m looking for a multimeter that can read as low as 20mv DC & AC ?I`m looking over the amprobe 5XP but I`m to new at this to be 100% sure so curious to here from the pro`s if this is the one I should get for what I want?Uses, gerneral very beginner electronics, vehicle, EMF polution, and body voltage readings, I`m trying to research a way to get a proper read of the voltage coming from my teeth and for those that don`t know anything about body voltage you should look over the Tooth meridian chart just Google (Free interactive tooth meridian chart) and then click on any tooth to see how it is linked with specicfic organs and functions lots of cool stuff if your into new things...Thanks for your time, please keep relies to positive non hatemonger typesI know some don`t like to learn new things but it`s not fair to discourage others, Peace.

Why would we expect you'll respect a suggestion about this when you have already started by not respecting our opinions? Sprinkling warm-fuzzy words around your admonition doesn't make it any less combative, in fact it sounds condescending.Quote from: T-rex on March 20, 2013, 09:13:05 pmMost decent DMMs can read this low. Just look at their specs. Divide the top of the lowest range by the number of counts to see the resolution (example: HP 3468A = 300mV, 300000 count = 1 uV resolution). I got it used for about $60. You should have no trouble finding a meter that can measure 20mV. Don't bother measuring AC, you'll just be measuring the mains radiation in your house.Of course,teethare very high-impedance sources, so you will have trouble with background noise. I suggest using the shielded probe on something likethis, possibly while inside a Faraday cage. Good luck with thatNow, since you suggested we would make fun of you, here's fulfilling your self-fulfilling prophecy: Do you know what they call alternative medicine that works?Medicine.And do you know what a "meridian" is? Because the muppets who wrote all these websites sure as hell don't. There's your clue.

content: I have to say, whoever is behind some of this stuff is pretty creative, the lowlife pieces of shit. Meridiantoothchart.com: "This connection is so apparent that an experienced dentist can often assess your overall health and wellness by reviewing your dental condition." Right, like people who don't brush their teeth probably neglect their health in other ways. And they're selling an "Interactive Meridian Tooth Chart" for - get this - $149. (Dude, if the tooth thing doesn't work out for you, I'm selling a Meridian Ass Hair Chart for only four payments of $99! And forget electronic interactivity, it's scratch-n-sniff! Currently looking for research participants to learn whether the effects can be extended by combining the two.) Toothwizards.com sells special "blotting brushes" (they look like the brushes my dadnicks fromsees atthe prison he works at, with a little plastic widget) for $4 ea., quantities of five. Apparently the upper right third molar is associated with compassion - I had mine pulled, must be why I'm such a prick. And "Do you brush your teeth with sandpaper? See pictures of abrasive particles in popular toothpastes" - because anyone who falls for this is surely enough of a dumbass not to understand the function of toothpaste.That's it, I've had enough. My blood is starting to boil. Which tooth should I stimulate to relax myself? And how do I do that - would my megger be enough?

content: Quote from: T-rex on March 21, 2013, 12:23:45 amDude, fuck you. I tried to be as helpful as I could (OK, in my first comment). There wasn't much I could do, because measuring the voltage of a tooth is not an easy problem to solve. I told you most meters could measure that voltage (I missed the part where you asked about a specific one - yes, that one can measure in 0.1mV steps), I explained the impedance problem and tried to show you that it would be very difficult to properly take such a measurement. Sure, I was a bit crotchety because of your preemptive admonition, but I wasn't bullying anyone.Also, lighten up. You keep throwing around "happy words" and emoticons to give the impression that you are, but that's not what the words say. Even if you are right and we are wrong, you have to admit it sounds a bit humorous. That's not an insult - I'm a musician and you should hear some of the terms we use. You'd think it was all not-so-subtle code for sex acts. I don't feel insulted when someone points that out.Maybe my second comment was a bit harsh (though definitely tongue-in-cheek - come on, "Meridian Ass Hair Chart"?), but the harshness was not meant to be directed at you. I'm not trying to be mean, but I do disagree, I think you've been misled, and I do not think very highly of the people who are misleading you. So yeah, I'm going to have a bit of fun at their expense.And for God's sake stop with this whole "positive vs. negative" crap. Intelligence and advancement thrive on debate and discussion, and if something is "radical and new" you have to expect people aren't always going to take it 100% seriously. If you really think there's anything to your theory you should beproudto defend it and happy that people are taking the time to help you find any problems it might have.Quote from: T-rex on March 21, 2013, 12:26:04 amI did, and I read the web sites. That's why I was cranky. They are misleading, sleazy and full of blatant lies. Care to find me one that's not? Give me an actual URL to something that doesn't read like an 1800s patent medicine advertisement and I will happily read it.

We all pat each other on the back, "How interesting, you special snowflake" while we're all paralyzed from polio with special herbs shoved up our asses in the hope that they will cure us.

I really don't think you can do a proper tooth meridian chart without it. Sometimes you can find used ones on ebay at a reasonable price. Otherwise, you can build your own:http://www.instructables.com/id/Flux-Capacitor/

content: First of all, how do you actually define the voltage of a tooth? Where's the positive, and where's the negative terminal?But I would believe that you can actually get voltage from multimeter probes placed on your teeth, if they formed a cell somehow. The voltage will depend on various conditions in your mouth, but that is hardly a way to diagnose anything medically.

content: Quote from: SeanB on March 21, 2013, 05:48:03 pmFunny you should say that, Many years ago I had a metallic filling in a back tooth, I used to keep hearing the BBC radio 4 program and could tell people what was on the radio before it was turned on, I mentioned this to my dentist when having a check up, he was not surprised and said it meant that I had a loose filling in the upper jaw at the rear. He probed around found a suspicious filling removed it and replaced it with a non metallic one and the radio disappeared. He reckoned that the loose filling caused a resonant rectifying circuit with the near which being near the ear caused me to hear sounds when the conditions were right, apparently this was not the first time he had come across this.
