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 XYZ/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 Method of Operation

Press “Power” button on. To change

measuring unit (mV/m), push “UNIT” button

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 bodies cannot detect
them.

4 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 (mV/m). This meter measures electric
field strength directly.

HF-B8G

EN-4

4.1 Magnetic Field Strength (H)
A field 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 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 Milliwatts 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

HF-B8G

EN-5

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
be 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.

 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”.
