General Hints for Measuring
As the field strength increases when coming closer to sources of
EMF pollution, it is possible to locate these by following the higher
readings until reaching the emitting source. The tone signal pro-
vided facilitates this process. As fields (especially magnetic fields)
can penetrate even massive construction material, the sources
might even be located outside the building, e.g. high-tension
power lines, electrified railway trails, transformers as well as
neighbouring houses and apartments.
Ideally, all measurements are to be repeated during various times
of the day and on different days of the week in order to identify
fluctuations.
Measurement Instructions – Electric Fields
According to relevant guidelines (TCO etc.), the field meter should
be connected to ground potential in order to obtain reliable, re-
producible testing results.
Grounding the Field Meter:
Insert the plug of the enclosed grounding cable into
the dedicated socket of the meter
ble along the side of the case to the back (see pic-
ture). Make sure that neither the grounding cable nor
the user's hand is in the front of the meter (falsifies the
reading!).
Unvarnished metal piping for water, gas or heating is especially
adequate for grounding with the grounding cable, if need be a
small blank wire will help making the contact. A large nail in the
wet ground of the garden is fine, too. Professionals can also use
the earth contact of a wall socket.
Turn on the field meter and set it to "E" (ME 3840B: Set the filter
to "50 Hz"). Keep the meter close to your body. The further away
from the body it is held, or if it is even put down, the more the
testing results tend to become distorted into the higher range.
During testing please make sure that the person performing the
survey, as well as anybody else present, is located behind the
meter. Proceed as follows:
Move slowly through the room to be measured. Stop fre-
quently and take measurements pointing to all directions in-
cluding ceiling and floor.
Move into the direction of the highest reading in order to iden-
tify the field source.
In places where people spend substantial amounts of time,
such as in bed or at a workplace, check all directions as men-
tioned above until you have reached the maximum reading at
the spot, where the body of the person would be located.
