ME 3840B only: Frequency Analysis
AC fields are not only defined by their field strength, but also by
the frequency with which the polarity of the field changes. The
ME3840 B can separate the following common frequencies and
frequency bands:
1) 5 Hz to 100 kHz
Good for overall considerations.
2) 16.7 Hz
Overhead railway wires in Germany, France, Norway, Austria,
Sweden and Switzerland.
3) 50 Hz to 100 kHz
Electric power grid and its harmonics.
4) 2 kHz to 100 kHz
"Artificial harmonics" above 2 kHz (e.g. from many AC-adaptors,
energy-saving bulbs, TV-sets). Corresponds to band 2 of the
Swedish TCO guideline. A factor 10 lower safe limits are rec-
ommended for this range!
Battery, Auto-Power-Off, Low batt.
The meter is powered by a 9 V battery, situated in the battery
compartment on the back of the meter.
The meter will automatically be shut off after 40 minutes of con-
tinuous use in order to save battery capacity.
When "Low. Batt." appears in the centre of the display, the field
meter will be turned off after 3 min. in order to avoid measurement
errors.
Possibilities of Remediation
If possible, increase the distance to the source of pollution
Correct "Plugging":
Switch the meter to "E" and place it between e.g. the bedside
light and the pillow. Switch off light. Reverse direction of plug by
180° and re-insert it. Logical: leave plug in the direction of lowest
readings. This trick works best for an inline cable-switch of e.g.
the lamp.
Use shielded socket-lines with two pole switch and shielded con-
nection cables (for available versions check our website).
Install an automated "demand switch" in the house fuse box
which cuts out electricity as soon as the last load is switched off
and automatically reconnects as soon as electricity is needed
again. As long as everything is switched off, there is no tension on
the line and hence no pollution in the room. This is the most com-
fortable
and
effective
measure
you
can
take.
