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

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.

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.
