    I have a problem with handheld voltage testers for electric fences. When other people hold them on a hot wire, they get consistent readings of the voltage, but when I do, I get values that are half or less. I have been trying to troubleshoot this for years and it doesn't have anything to do with how I hold it (pressure or position), what shoes I am wearing, how I am standing, etc. I don't weigh much, but others similar in size to me still get much higher readings. If I hold the voltage tester on a wire and someone else lightly touches the tester at the same time with just a finger, the reading instantly jumps higher. It is a problem specific to me! What could cause this? Anemia? Lol! Thanks!

    Most electric fence testers (at least the ones that I've used) actually measure electric fields, and not voltages directly, although they often report readings as voltages. These are the ones with just a single probe. This type will be sensitive to "antenna effects" of the same type that an older generation might remember experiencing with TV reception over "rabbit ears". My guess is that you are slender, so you aren't as bulky an antenna as some other folks.

    There are testers that actually do measure voltage directly. They require two connections to read properly (voltages are properly defined only between two points, so you need more than a single probe). Their readings will be unaffected by your dimensions.

    Or eat lots of beef.
