Discussion Overview

The discussion revolves around the phenomenon of a voltmeter registering a strong reading when touched to a person's skin, despite the individual claiming not to be in contact with any electrical current. Participants explore potential explanations for this occurrence, including the functionality of the voltmeter and the nature of electrical measurements.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions the validity of the voltmeter reading, suggesting that minimal voltage or current should be detected when touching the skin.
  • Another participant proposes that the voltmeter might be set to measure resistance (ohms), which could explain a strong reading if the leads are held in different hands.
  • A participant clarifies that the voltmeter is set for household use and that they are not touching any other conductive surface, raising questions about the measurement process.
  • One participant suggests that non-contact voltmeters could measure the charge on the skin, likening the measurement to a capacitor setup.
  • Another participant confirms that they experience a strong reading when touching their skin, regardless of the environment, indicating a consistent phenomenon.
  • A request is made for a link to an advertisement for the voltmeter to better understand its specifications and functionality.

Areas of Agreement / Disagreement

Participants express differing views on the expected behavior of the voltmeter when in contact with skin, with some questioning the readings and others providing potential explanations. The discussion remains unresolved regarding the exact cause of the observed phenomenon.

Contextual Notes

There are limitations in understanding the specific model of the voltmeter and its intended use, as well as the assumptions about the electrical properties of the human body in this context.

Can anyone out there tell me why a voltmeter would strongly register when I touch it to my arm, and yet I am in no contact with any electrical current? This seems outrageous to me. It is a commercially available pen tester bought at Home Depot and set on the highest setting.

I'm not really sure what you are talking about, you should be getting almost no volts or amps if u are touching it to your arm. Maybe you have it set on ohms? I imagine that would get a pretty strong reading, especially if you held on lead in one hand and one lead in the other.
 
I am touching nothing, the voltmeter is set for household use, and the other hand is free. Any ideas?
 
it is not set to ohms, it is really nuts.
 
if you are in So Cal, I would be glad to meet up with you and demonstrate this nutty phenom.
 
Voltage is measured between two points. One point is touching your arm, but what is the other point?

Or they do make non-contact voltmeters that, if I understand correctly, treat the surface you're measuring as one plate in a capacitor and the meter probe as the other plate and measure the charge across the plates. In that case, your arm might simply have a charge on it that the meter is measuring. I don't really know the details of these devices, but your pen might've come with a manual that tells you how it works.
 
I agree, I am supposed to touch a conductive plate around the electrical device, but i don't have to do that, all I am doing is standing (I've tried this in many rooms and outdoors) and if I make contact with any part of my skin on my arm or face the volt alarm sounds at its highest sound.
