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
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
electromagnetic fields

.

This meter is applied to measuring electromagnetic fields
of extremely low frequency
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), milli­Gauss (mG) or micro-Tesla (

1_T_10 mG

Switch between the display of micro-Tesla and milli­Gauss is available.

Press to power on.

Select for mG unit or for µT unit.

Position the front (refer to Figure 1) of the meter to
measure the electromagnetic waves. Try to change the
measurement angle or position for obtaining the highest
reading value (please refer to Figure 2 to 6).

Read the measured value. The display of “OL” on the left
highest position indicates there is an overload on the
reading. Please press to select a higher range for
measurement again.

Due to the environmental magnetic 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 device.

To permanently lock and keep the reading displayed on
the LCD, press or press again to unlock.

To retain the maximum value, press and the reading
value displayed on the LCD will keep updating to the
maximum value.
