I am new to the meter reading. Just bought one of these two days ago. Am checking everything. I moved my bed to the other side of the room. My question is, when I leave the meter laying on my bed, it reads very low in all three scales. But when I touch the meter, EF shoots up to 45-55. What is going on?

| Hi motherworld, from FAQ thread: "The EF is referring to Electric Field. In most of case, it appears to be Static Electric existed almost on any object surfaces. Include the surface of meter surface and human body. The EF can be transferred from one object surface to another. When you touching the meter, your body EF transferred to the meter, so the meter detected EF changes." |

| Is body-static (that causes the EF readout to soar) anything to be concerned about? Should the user ground themself? What is the correct way to get an accurate EF measurement with the GQ 390? Thank you |

| If you want to measure AC EF, then you dont need to touch the device. It is still better to hold the device while measuring EF though. Since you will know how much EF, static or not, your body is exposed to. |

My question is somewhat along the same line regards my 390 meter readings.
But adding that when I ground myself with my barefoot to a grounding mat in my office, with the grounding mat connected to a the ground source in the outlet, why does the meter jump to around 55 V/m from whatever reading I am receiving from whatever device I am measuring or pointing it at. It jumps to this similar number each time I am touching the ground mat contact surface.
When not touching it seems to give measures of what I am pointing the device at, but as soon as I make contact of my foot to the ground mat the contact causes the meter to jumps to 50 to 55 V/m.
Does this mean my body is holding a contant 55 V/m, or experiencing this EF from other surrounding sources?
Is it better to be grounded to a mat and equalized with the earth when measuring with the 390 device, or what should I be doing when measuring?
And if possible to explain what am I actually experiencing as measured shown by the gauge when grounded or not grounded?
Should I ground things in my office like a metal filing cabinet that up close give off 50 ish V/m, that lowers as I move away from the cabinet?
Thanks for your feedback,
TW

| It is possible but it is most likely the whole environment backgroud static is 55V/m |
