1. SAFETY INFORMATION
CAUTION
•When first use the meter or prolonged storage the meter,
please charge the meter at least 10 minutes then use the
meter.
•Before making a measurement, check if the low battery
symbol (
+
) is shown on the display as soon as the meter
is switched on or the battery remained capacity indicate
“ ” symbol only 20%, please charging the battery.
•Avoid shaking the meter, particularly in the measurement mode.
•The accuracy and function of the meter may be adversely
affected by the specified limits outside and improper handling.
DANGER !
•In some cases, work in the vicinityof powerful radiation sources
can be a risk of your life.
•Be aware that persons with electronic implants (e.g. cardiac
pacemakers) are subject to particular dangers in some cases.
•Observe the local safety regulations of the facility operation.
•Observe the operating instructions for equipment which is used
to generate, conduct or consumer electromagnetic energy.
•Be aware that secondary radiators (e.g. reflective objects such
as a metallic fence) can cause a local amplification of the field.
•Be aware that the field strength in the near vicinity of radiators
increases proportionally to the inverse cube of the distance.
This means that enormous field strengths can result in the
immediate vicinity of small radiation sources (e.g. leak in
waveguides, inductive ovens).

2
•Field strength measuring device can underrate pulsed signals.
Particularly with radar signals, significant measurement errors
can arise.
• All field strength measuring devices have a limited specified
frequency range. Fields with spectral components outside of this
frequency range are generally incorrectly evaluated and tend to be
underrated. Before using field strength measuring devices, you
should thus be certain that all field components to be measured lie
in the specified frequency range of the measuring device.
2. INTRODUCTION
2-1 Fundamentals
Electromagnetic pollution:
This Meter used to indicate electromagnetic pollution
generated artificially. Wherever there is a voltage or a
current, the electric (E) and magnetic (H) fields arise. All
types of radio broadcasting and TV transmitters produce
electromagnetic fields, and they also arise in industry,
business and the home, where they affect us even if our
sense organs perceive nothing.
Electric field strength (E):
A field vector quantity that represents the force (F) on an
infinitesimal unit positive test charge (q) at a point divided by
that charge. Electric field strength is expressed in units of
volts per meter (V/m).
Use the units of electric field strength for measurements in the
following situations:
•In the near-field area of the source.
•Where the nature of the electromagnetic field is unknown.

3
Magnetic field strength (H):
Afield vector that isequal to the magnetic flux density divided
by the permeability of the medium. Magnetic field strength is
expressed in units of amperes per meter (A/m).
The meter uses of magnetic field strength for measurements
only in the far-field area of the source.
Power density (S):
Power per unit area normal to the direction of propagation,
usually expressed in units of watts per square meter (W/m
2
) or,
for convenience, units such as milliwatts per square
centimeter (mW/cm
2
).
The characteristic of electromagnetic fields:
Electromagnetic fields propagate as waves and travel at the
speed of light (c). The wavelength is proportional to the
frequency.
λ(wavelength) =
c
(
speed of light
)
f (frequency)
If the distance to the field source is less than three
wavelength, then we are usually in the near-field. If the
distance is more than three wave length, the far-field
conditions usually hold.
In the near-field, the ratio of electric field strength (E) and
magnetic field strength (H) is not constant, so we have to
measure each separately.
In the far-field, however, it is enough to just measure one field
quantity, then the other could be computed accordingly.

4
2-2 Application
Quite often routine operation, maintenance and service work
has to be done in areas where active electromagnetic fields are
present, e.g. in broadcasting stations, etc. Additionally, other
employees may be exposed to electromagnetic radiation. In
such cases, it is essential that personnel are not exposed to
dangerous levels of electromagnetic radiation, such as:
High frequency (RF) electromagnetic wave field strength
measurement.
Mobil phone base station antenna radiation power
density measurement.
Wireless communication applications (CW, TDMA, GSM,
DECT).
RF power measurement for transmitters.
Wireless LAN (Wi-Fi) detection, installation.
Spy camera, wireless bug finder.
Cellular/Cordless phone radiation safety level.
Microwave oven leakage detection.
Personal living environment EMF safety.

2-3 Features
The meter is a broadband device for monitoring high-frequency
radiation in the range from 10MHz to 8GHz. The
non-directional electric field and high sensitivity also allow
measurements of electric field strength in TEM cells and
absorber rooms.
The unit of measurement and the measurement types have
been selected to expressed in units of electrical and magnetic
field strength and power density.
At high frequencies, the power density is of particular
significance.
It provides a measure of the power absorbed by a person
exposed to the field. This power level must be kept as low as
possible at high frequencies.
The meter can be set to display the instantaneous value or the
maximum value measured. Instantaneous and maximum value
measurements are useful for orientation, e.g. when first entering
an exposed area.
10MHz to 8GHz Frequency range
For isotropic measurements of electromagnetic fields
Non-directional (isotropic) measurement with three-channel
measurement sensor.
High dynamic range due to three-channel digital results
processing.
Configurable alarm threshold and memory function
Use rechargeable lithium-ion battery pack
LCD backlight function
Easy & safety to use

4-3 Use E-field sensor
The actual 3-channel sensor is located in the head part of the
meter. The three voltages generated by the sensor are fed back
to the meter. In far-fields, an E-field sensor is preferable due to
the greater bandwidth. The E-field sensorfor frequencies is from
10MHz to 8GHz.
The meter is a small portable instrument that measures the electric
field presented in the atmosphere of the measurement sensor
surroundings.
The measurement of the field is done by moving the aerial of the
sensor in the desired measured environment.
You obtain a direct wide band measurement of the field that the
measurement sensor is subjected to. To find the value of the
field emitted by a source of interference, simply point the aerial
towards it and get as close as possible (the value of the field is
inversely proportional to the distance of the sensor/emission
source). The operator must take care not to be between the
source of disturbance and the zone to be checked: the human
body shields electromagnetic fields. The E-field sensor is
isotropic, it does not require special handing. Its sensitive part
measures the field according to 3 axes without the aerial having
to be moved in the 3 planes. Simply point it at the target to
make the measurement.
4-4 Explanatory notes
4-4-1 Units of measurement
The meter measures the electrical component of the field, the
default units are those of electrical field strength (mV/m, V/m).
The meter converts the measurement values to the other units
of measurement, i.e. the corresponding magnetic field
strength units (µA/m, mA/m) and power density units (µW/m
2
,
mW/m
2
, W/m
2
, µW/cm
2
or mW/cm
2
) using the standard
far-field formulate for electromagnetic radiation.
The conversion is invalid for near-field measurements, as
there is no generally valid relationship between electrical and
magnetic field strength in this situation. Always use the default
units of the sensor when making near-field measurements.

14
4-4-2 Result modes
The bar graph display always shows each axis (X, Y or Z)
the instantaneous measured dynamic range value. The
digit display shows the instantaneous or result according to
one of three modes which can be selected :
•Instantaneous: The display shows the lastvalue measured
by the sensor, no symbol is displayed.
•Maximum instantaneous (MAX): The digital display
shows the highest instantaneous value measured, the
“MAX” symbol is displayed.
•
Maximum average (MAX AVG) : The digital display shows
the highest average value measured, the “MAX AVG” symbol
is displayed.

Field strength
4-4-3 Calibration factor (CAL)
The calibration factor CAL serves to calibrate the result
display. The field strength value measured internally is
multiplied by the value of CAL that has been entered and
the resulting value is displayed. The CAL setting range is
from 0.20 to 25.00.

15
The CAL factor is often used as a means of entering the
sensitivity of the field sensor in terms of its frequency
response in order to improve measurement accuracy.
Frequency-dependent sensor calibration factors are provided
for this application. In many cases, the measurement
accuracy will be sufficient even if the frequency response of
sensor calibration factoris ignored. CALcan be set to 1.00 in
such cases.

The alarm limit value is used to monitor the display value
automatically. It controls the alarm indication function. The
alarm limit value can be edited in the displayed V/m unit.
