About this manual
The ESM-30 “RadMan XT” differs from the
ESM-20 “RadMan” and ESM-10 “RadMan
Mobile” because it includes an additional data
recorder. The term ESM “RadMan” is used in
this manual to refer to all three versions.
Information that only applies to the ESM-30
“RadMan XT” is prefaced by “ESM-30 only”.
Information that only applies to the ESM-10
“RadMan Mobile” is prefaced by “ESM-10
only”.
Application
Early warning is required wherever humans
are likely to be directly threatened by the
presence of strong electromagnetic fields.
Antenna and radar equipment and machines
which use strong electromagnetic fields to
heat, weld or bond materials are typical
sources of dangerous electromagnetic fields.
The ESM “RadMan” is a small, handy test and
warning instrument which provides safe and
timely warning of electromagnetic fields in
these areas of application.
ESM “RadMan” measures according to the
usual standards covering exposure to
electromagnetic radiation.
Application and use
Introduction
6
Use
The handy shape of the ESM “RadMan”
makes it ideal for three main areas of use:
As a warning unit – ESM “RadMan” is
worn on the body by attaching it to clothing
using the clip or to a belt using the belt
pouch supplied.
As a monitor unit – ESM “RadMan” is used
to check beforehand that limit values are
not exceeded in areas where humans are
present.
To reduce the effects due to the body as
far as possible, ESM “RadMan” is held at
arm’s length or the extension rod is used
(option).
As a locating unit – ESM “RadMan” can be
used to locate leaks on waveguides and
coaxial screw connectors.
ESM-30 only:
As a data recorder – ESM-30
“RadMan XT” automatically records all
measurement values continuously. The
data can be displayed and evaluated on a
PC using the ESM-TS Interface Set, which
is available as an option. All evaluations
can be summarized in a report.
Application and use
Introduction
7
Functions and features
In contrast with other instruments, the six
sensors of the ESM “RadMan” independently
monitor all the components of the electric and
magnetic fields of a signal. This means the
device can always measure the strongest field
component. ESM “RadMan” measures
isotropically, i.e. non-directionally.
International and national bodies have set
different limit values for permissible
electromagnetic radiation levels in various
standards and regulations. Different versions
of ESM “RadMan” are available to cover these
differences (see page 56).
Power is supplied from two standard batteries,
giving a typical operating time of 200 hours.
A wide range of accessories ensures that the
unit can be optimized for each particular type
of application.

General instructions governing the use of
field strength measuring equipment
Do not touch or use the field strength
meter to touch items carrying dangerous
voltages.
Make sure that you know which laws,
standards and regulations apply in your
area. Read the operating manual carefully
and seek expert advice if anything
requires clarification.
A selection of current standards and
regulations is listed in this manual (see
page 38).
Be advised that working in the vicinity of
strong radiation sources can endanger life.
Be advised that persons fitted with elec-
tronic implants such as heart pacemakers
may be especially at risk.
Observe the local safety precautions
specified by the operator of the plant or
equipment.
Make sure you follow the operating
instructions when using equipment which
generates, transmits or uses electromagnetic energy.
Warning
Warning instructions
11
Safety
Never place or hold field strength
measuring equipment inside field
generating equipment or machines (e.g.
microwave ovens or induction furnaces) as
this may result in destruction of the field
strength measuring equipment which is
not designed to withstand field strengths
intended for materials processing.
Be advised that field strength increases
rapidly in the near-field region (the field
strength will be eight times higher if you
halve the distance to the source).
Enormous field strengths can occur in the
immediate vicinity of radiation sources
(e.g. leaks in waveguides, induction
furnaces).
All field strength measuring equipment
has a limited and specified frequency
range. Fields with spectral components
outside this frequency range will normally
not be evaluated correctly and may be
underestimated. Before using field
strength measuring equipment, make sure
that all the field components to be
measured are within the specified
frequency range of the measuring
equipment.
Be advised that secondary radiators
(reflecting objects, such as a metal fence)
may result in local amplification of field
strength.
Warning instructions
12
Safety
The safety of persons within
electromagnetic fields must not be based
purely on the measured values produced
by field strength measuring equipment,
since the built-in redundancy is not
sufficient to ensure that the instruments
will always function correctly at all times.
Be advised that the electromagnetic field
strength may be underestimated by the
field strength measuring equipment if your
body is interposed between the radiation
source and the field strength measuring
equipment.
Be advised that field strength measuring
equipment cannot cover all aspects of a
standard or regulation. Please therefore
check the specifications to ascertain the
extent to which the field strength
measuring equipment meets the
requirements of the applicable standard.
Be advised that an underestimation of the
electromagnetic field strength cannot be
excluded if the field strength measuring
equipment is worn on the body.
The ESM “RadMan” has been specially
constructed to exclude the possibility of
underestimating the electromagnetic field
strength as far as possible.
Warning
Warning instructions
13
Safety
Be advised that field strength can be
attenuated by wet clothing. ESM
“RadMan” should be worn outside the
clothing to exclude the possibility of
underestimating the electromagnetic field
strength.
Be advised that any kind of sticker or
metallic label in the sensor area may lead
to underestimated electromagnetic field
strengths.
Please note that the data stated in the
specifications only applies under free field
conditions. Neither the effects due to the
person making the measurement nor the
device behavior in the near field are taken
into account.
Be advised that the strengths of pulsed
signals (e.g. radar signals) may be
wrongly estimated by field strength
measuring equipment. The ESM
“RadMan” is however designed so that
with the type of radar signals normally
encountered it deviates slightly from the
actual rms value. The 2250/01 and 2250/
06 models are particularly recommended
for the BGV B11 and ICNIRP standards,
which stipulate a special evaluation
method for such signals.
Contact your Sales Agent for more
information, quoting the reference
“Radar Application Note”.

Safety
Strong, low-frequency electrical fields, for
instance in the vicinity of high-voltage
cables, may sometimes influence the
displayed value, especially when the ESM
“RadMan” is used as a rapid tester or as a
leak locator.
