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 families
and work locations where electromagnetic fields are detected
the strongest in order to avoid prolonged exposure to excessive
lectromagnetic fields.

2 Application
 This meter is applied to measuring electromagnetic fields
of extremely low frequency (ELF) of 30 to 2000Hz.
 It is capable of measuring the electromagnetic field
radiation intensity that is produced from electric
transmission equipment, power line, microwave oven, air
conditioner, refrigerator, computer monitor, video/audio
device 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 user 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 micro Tesla(u T) or milli Gauss(m G) 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
or 9999 data sets(192D).
 USB PC interface (192D).
 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
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 field reading, press key to independent three
single-axis magnetic field readings and triaxial total
magnetic field reading.
 To permanently lock and keep the reading displayed on
the 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 lower than 0.5mG 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
measurement, the reading of tester should return to zero,
unless there is the electromagnetic from other sources are
detected.
