I have got thr Entech dirty electricity meter.
It is manufactured by Alphalab. On the ouside it says 120 V and 60 Hz, but when you open it, there are three small bridges which have to be changed, so that it wil work also on 200 V and 50 Hz. There is however no analogy to the Stetzerizer meter. With a friend it let hear real radio signals, and comparison to a normalradio, this radio station was at ca. 700 kHz. So pretty high. I have a main switch to cut all electricity for my computer. When the current is off, I hear a lot of noise and e meter reading of 150. A filter placed cuts the noise amd th value changes to 30. But the same happens when I let the current go to my computer. That is strange, because one would expect the the computer plus stuff should cause *dirty power*. The Stetzerizer meter does not change its value of 9 while all this happens. Measuring with a spectrumanalyser does not show either. So it is a bit strange what it really does. Of course, a CFL bulb causes the Entech meter to rise. So I have to play more with it.

I am surprised by how it responds to your computer. Is it a regular
computer or does it have a special power supply or filter? I have the same meter. Of course it does not measure common mode noise, only differential mode. I was a bit surprised how different the readings are at different outlets in the house. It seems the signal can drop off noticeably after 30 feet of wiring (or is it inductance when the wires hit a junction box?). By the way Charles, do you know which countries in Europe use Delta or Wye distribution systems (if you use those terms)? Here, most places are now Wye, but some older areas are still Delta. In Wye, the neutral wire is grounded to earth at every home and every transformer and every overhead pole. In Delta, the neutral wire is never grounded (or in uni-grounded Wye, it is grounded only at one spot).

Hello Bill,
I also am surprised and are wondering what thgis meter is *metering*. I believe that the system used overhere is as described by you as Delta. Also, I found that on the main line with several wallsockets, the readings differ for no apparent reason. In the kitchen, one plug shows 10, the next one (1,5 meter away) shows 30 and a third (1.5 meter away) shows 67, which is close to the cooking gas plate, where only electricity is used for the piezo lighter, and the vapour exhaust (not working). The first plug is ca 3.5 meter away from the fridge, so that does not seems to have any influence. When I plug in the coffeemachine in the first socket, the value of 10 rises to 30. So, I am confused what this is all about. I do not have a leakage current. My earth leakage circuit breaker with 30 mA would stop, if that was the case, when I plug in my grounding measuring meter in. This meter needs 15 mA, so anything above that makes the breaker halt.

I guess the thing to do is sniff around with an AM radio
near those outlets. In my case some of it is from a local radio station, so some outlets seem to be better antennas than others. I had an exhaust fan over the stove at my old house that turned out to have a transformer in it to regulate a shut-off timer and low-voltage switches, so it was on even when off. If you are up for a more complex project, there is an air-band radio made by Ramsey electronics. It is all passive--no local oscillator, and is designed to pick up all frequencies in the band at once (no tuning). It is sold as a kit or pre-assembled. The pre-assembled one is a pretty good EMF detector. Whether it's worth the cost given how well a regular AM radio works is unclear. But the receiver in principle goes from DC to 1 GHz. The frequencies beyond airband are filtered out first. So if one were to bypass the filters... Of course then one has to consider antennas. Not clear this is worth the trouble for a device that will not be precise or calibrated, but I'm hoping to do it in the coming months...

Puk replies - Some cooker hobs on the surface of the worktop can reach very
high efeilds in my experience, the metal attached to gas and electricity cables acts as a good re-radiator, I now light my gas with a portable gas lighter because of this.
