MG-2000T/MG-2000TD
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.

MG-2000T/MG-2000TD
2. Application
This meter is applied to measuring magnetic
fields of extremely low frequency (ELF) of 30 to
2000Hz.
It 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.
The 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
Uses three internal orthogonal sensors to test a
wide range of ELF magnetic fields, independent
of measurement angle.
The 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.
The 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.
Display microTesla(uT) or milliGauss(mG) units.
Data hold (HOLD), maximum Hold (MAX), and
minimum Hold(MIN) function.
Auto range or manual range select mode.
Datalogging capacity with Memory Size：500
data sets (Model 192) or 9999 data sets(Model
MG-2000TD).
USB PC interface (MG-2000TD).
Time and calendar function.
Low battery indication “ ”.
Over load display “OL”.
Auto power OFF function .

5. Measurement Procedures
Press “ ” key turn on the meter, press “ ”
key again to turn OFF the meter.
Press “ ” key to select milli-gauss (mG) or
micro-tesla (µT) unit.
Position the front of the meter to measure the
magnetic waves.
Read 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.
The 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.
To lock and keep the reading displayed on the
6
MG-2000T/MG-2000TD
LCD, press “ ” or press “ ” again to
unlock.
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 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.
With the tester in hand, move slowly towards to
the object under measurement until it is
physically touched.
Notice how the field intensity increases as you
move closer to the object.
If the power of object was turned off during the
7
MG-2000T/MG-2000TD
measurement, the reading of tester should return
to zero, unless an electromagnetic field from
other sources is detected.
6. Clock setup
This meter clock uses 24 hour time.
Press “ ” key to enter clock setting mode
(1.SET).
Press “ ” or “ ” key to select option to
adjust.
Press “ ” or “ ” key to change the digit.
Press “ ” key to store the setup, exit the
8
MG-2000T/MG-2000TD
mode.
7. Auto power off setup
Press “ ” key again to auto power off time
settingmode(2.SET).
Press “ ” or “ ” key to change the auto
power off time.
Press “ ” key to store the setup, exit the
mode.
The auto power off time default value is 5
minutes. Range is 0 to 99 minutes. To cancel
auto power off, please set time to 0 minutes.
