Axis RF Meter Quick Start Guide
This meter has many capabilities,
including memory, alarm, date/time,
average etc. which will require some study
of the manual to use properly. However,
you can quickly and easily begin making
measurements right out of the box. Just
follow these simple steps:
1. Insert 9V battery.
2. Turn meter on with GREEN button.
3. Press XYX/MEM button until all three
(XYZ) letters are displayed on the
screen (to the left of the main number.
4. Press UNIT/ENTER button until the
desired units are displayed below the
main number (we recommend using
mV/m… and we recommend a
maximum level of 614 mV/m for
prolonged exposure).
You are now ready to make your first
measurements!

1 Introduction
This meter is designed for measuring and
monitoring Radio–Frequency
electromagnetic field strength. The meter
is calibrated precisely over the frequency
range of 10MHz~8GHZ.
2 Simple a method of operation
Press “power” button on.To change
measuring unit (mV/m), push UNIT”button to
change the unit.Electric field strength
(V/m).Computed magnetic field strength
(mA/m).Computed power density
(mW/m2).Computed power density
(μW/cm2).
Press "xyz” this key to change sensor axis
selector:
“All axis ” →“X axis” →“Y axis” →“Z
axis”.

3 Fundamentals
Electromagnetic pollution
This meter is used to indicate electromagnetic
pollution generated artificially. Wherever there
is a voltage or a current, 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.
4 Electric field strength (E)
Afield 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 (mV/m). This meter measures
electric field strength directly.
4.1 Magnetic field strength (H)
Afield vector that is equal 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). In far field situations, one can

EN-4
calculate the magnetic field for the electric
field value. This meter can display the
calculated magnetic field strength.
4.2 Power density (S)
Power per unit area normal to the direction
of propagation, usually expressed in units
of watts per square meter (W/m2) or, for
convenience, units such as mill watts per
square centimeter (mW/cm2)
4.3 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 wavelengths, then we are
usually in the near field. If the distance is
more than three wavelengths, the far-field
conditions usually hold.
In near field conditions, the magnetic field
value cannot be calculated from the
electric field value. This meter is designed
for reliable far field measurements only.

5 Application
Quite often routine, 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 be not exposed to dangerous
levels of electromagnetic radiation, such
as:
High frequency (RF) electromagnetic
wave field strength measurement.
Mobile 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.

6 Features
The meter is a broadband device for
monitoring high- frequency radiation in
the range from10MHz to 8GHz
The non-directional electric field antenna
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, the maximum value
measured or the average value.
Instantaneous and maximum value
measurements are useful for orientation,
e.g. when first entering an exposed area.

EN-7
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.
Easy & safe to use
Low battery detector “ ”.
Manual data memory storing: 200 data
sets.
Memory Over load indication “OL”.
