INTRODUCTION
Safety precautions should be taken against
electric appliances in places including medical
institutions, schools and residential districts,
where people usually stay a long time, to prevent
patients, babies and snior citizens from exposure
to high electromagnetic waves.
An electromagnetic wave simply means the wave
motion of the electromagnetic eld (EMF).
The change in electric elds produces magnetic
elds, and the change in magnetic elds can
also generate electric elds. The uctuation
of correlation between each other is known
as “electromagnetic waves”, which is a form
of energy simular to light and heat that can be
transmitted either bt radiation in the air or by an
electric conductor.
It is suggested that rearragements should be
made in homes and work locations where the
strongest electromagnetic elds are detected in
order to avoid prolonged esposure to excessive
electromagnetic elds

APPLICATIONS
• This meter is applied to measuring magnetic
elds of extremely low frequency (ELF) of
30 to 200 Hz.
• It is capable of measuring the magnetic eld
radiation intensity that is produced from electric
transmission equipment, power lines, microwave
ovens, air conditioners, refrigerators, computer
monitors, video/audio devices and so forth.
• The magnetic eld unit is Tesla (T), Gauss (G),
milli-Gauss (mG) or micro-Tesla (µT).
1 T = 10,000 G
1 G = 1,000 mG
1 µT = 10 mG

6
FEATURES
• Uses three (3) internal orthogonal sensors to test
a wide range of ELF magnetic elds, independent
of measurement angle.
• The tester is designed to provide a quick, reliable
and easy way to measure magnetic eld radiation
levels around power lines, home appliances and
industrial devices.
• The tester is a cost-e󰀨ective hand-held instrument
that was designed and calibrated to measure
magnetic eld radiation at di󰀨erent bandwidths
from 30 Hz to 2000 Hz.
• Display micro-Tesla (µT) or milli-Gauss (mG) units.
• Data hold (HOLD), maximum Hold (MAX), and
minimum Hold (MIN) function.
• Autorange and manual rage select mode.
• Datalogging capacity memory size: 500 data sets
• Time and Calendar fuction
• Low battery indication
• Overload display “OL”
• Auto power OFF function

MEASUREMENT PROCEDURES
• Press key turn on the meter, press turn
key again to OFF the meter.
• Press key to select milli-gauss (mG) or
micro-tesla (µT)
• Position the front of the meter to measure the
electromagnetic waves.
• Read the measured value. When manual range
select mode. LCD will shown the ®mark. The
display of “OL” on the highest position indicates
there is an overload on the reading. Press
to select a higher range for measurement again.
• This meter displays the default value is triaxial
total magnetic eld reading, press key to
independent three single-axis magnetic eld
readings and triaxial total magnetic eld reading.
• To permanently lock and keep the reading
displayed on the LCD, press or press
again to unlock.

10
MEASUREMENT PROCEDURES
• To retain the maximum and minimum value,
press key and the reading value displayed
on the LCD will keep updating to the maximum
value. Press again to select minimum value,
press and hold down key 2 seconds to exit
the maximum and minimum mode.
• Due to the magnetic interference of the
environment eld factors, this magnetic eld
meter could display a reading value that is
lower than 0.5 mG prior to measuring. This is
not a malfunction of the tester.
• With the tester in hand, move slowly towards
to the object under measurement until it is
physically touched.
• Notice how the eld intensity increases as you
move closer to the object.
• If the power of object was turned o󰀨 during the
measurement, the reading of tester should return
to zero, unless there is the electromagnetic from
other sources are detected.
