Made in Germany
Please note:
Quick movements induce short peaks of pseudo readings that
have nothing to do with actual fields (due to the earth's static
magnetic field)
Let the display settle for 2 seconds after every change of direc-
tion.
Recommended Exposure Limit AC Magnetic Field:
Below 200 nT, preferably below 20 nT
For frequencies above 2 kHz significantly lower readings are to be desired.
Conversion table nT to mG,
that is Nanotesla to Milligauss, on the last page of this
manual.
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. Your instru-
ment can separate the following common frequencies and frequen-
cy bands:
5 Hz to 100 kHz ME3851A / 400 kHz ME3951A
Not recommended for hands-free measurements.
16.7 Hz
Overhead railway wires in Germany, France, Norway, Austria, Swe-
den and Switzerland.
50 Hz to 100 kHz ME3851A / 400 kHz ME3951A
Electric power grid and its harmonics.
2 kHz to 100 kHz ME3851A / 400 kHz ME3951A
"Artificial harmonics" above 2 kHz (e.g. from many AC-adaptors,
10
(Magnetic flux density at 50/60 Hz).
