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

2. Application
zThis meter is applied to measuring magnetic
fields of extremely low frequency (ELF) of 30 to
2000Hz.
zIt is capable of measuring the magnetic field
radiation intensity that is produced from electric
transmission equipment, power lines, microwave
ovens, air conditioners, refrigerators, computer
monitors, video/audio devices and so forth.
zThe magnetic field unit is Tesla (T), Gauss (G),
milli-Gauss (mG) or micro-Tesla (μT).
1 T＝10,000 G 1 G＝1,000 mG
1μT＝10 mG

3. Features
zUses three internal orthogonal sensors to test a
wide range of ELF magnetic fields, independent
of measurement angle.
zThe tester is designed to provide a quick, reliable
and easy way to measure magnetic field radiation
levels around power lines, home appliances and
industrial devices.
zThe tester is a cost-effective hand-held
instrument that was designed and calibrated to
measure magnetic field radiation at different
bandwidths from 30Hz to 2000Hz.
zDisplay microTesla(uT) or milliGauss(mG) units.
zData hold (HOLD), maximum Hold (MAX), and
minimum Hold(MIN) function.
zAuto range or manual range select mode.
zDatalogging capacity with Memory Size：500 data
sets (Model 192) or 9999 data sets(Model 192D).
zUSB PC interface (192D).
zTime and calendar function.
zLow battery indication “ ”.
zOver load display “OL”.
zAuto power OFF function .

5. Measurement Procedures
zPress “ ” key turn on the meter, press “ ”
key again to turn OFF the meter.
zPress “ ” key to select milli-gauss (mG) or
micro-tesla (µT) unit.
zPosition the front of the meter to measure the
magnetic waves.
zRead the measured value. When manual range
mode is
selected, 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.
zThe default value display is triaxial total magnetic
field reading. Press “ ” key to toggle between
independent three single-axis magnetic field
readings and triaxial total magnetic field reading.
zTo lock and keep the reading displayed on the
LCD, press “ ” or press “ ” again to
unlock.

zTo retain the maximum and minimum value,
press “ ” key and the reading value displayed
on the LCD will keep
zupdating to the maximum value. Press again to
select minimum value, press and hold down
“” key 2 seconds to exit the maximum and
minimum mode.
zDue to the magnetic interference of the
environment field factors, this magnetic field
meter could display a reading value that is
greater than 0.5 mG prior to measuring. This is
not a malfunction of the tester.
zWith the tester in hand, move slowly towards to
the object under measurement until it is
physically touched.
zNotice how the field intensity increases as you
move closer to the object.
zIf the power of object was turned off during the
measurement, the reading of tester should return
to zero, unless an electromagnetic field from
other sources is detected.
