1.1 Measuring electromagnetic fields
In today’s world, practically everyone lives and works in an
environment surrounded by technical equipment that gener-
ates electromagnetic fields. Our recognition of the problems
associated with such fields and our depth of information in
this area has increased as the effects of such fields on the
human body have been examined more closely. Various
authorities have long defined limit values designed to pro-
tect users from the dangers of exposure to such emissions.
1.2 About this instrument
The Narda Industrial Meters NIM-511 and NIM-513 com-
bine an unprecedented ease of operation with powerful
measurement capabilities. It provides the industrial plant
manager and safety professional with an accurate and inex-
pensive solution for proving compliance with regulations
that cover exposure to RF radiation. Both models provide a
complete measurement system comprised of an extremely
easy to operate meter (NIM-510) and a probe (NIM-511 or
NIM-513) that contains sensors to measure both the electric
(E) and magnetic (H) field components of an electromag-
netic wave.
The NIM-513 operates from 10 MHz to 42 MHz and is
adjusted to the reference calibration frequency at
27.12 MHz. The NIM-511 has a much broader sensor that
operates from 300 kHz to 100 MHz and is adjusted to the
reference calibration frequency at 13.56 MHz.
1.2 About this instrument
Narda NIM-51x 3
Applications
Major safety standards worldwide require that both the elec-
tric and the magnetic field components (E and H fields) be
measured for equipment operating below 300 MHz. Most
high power industrial equipment operates at one of the fre-
quencies allocated for Industrial, Scientific, and Medical
(ISM) applications. Two ISM frequencies – 27.12 MHz and
13.56 MHz – are used extensively. The majority of heat
sealers and induction heaters operate at 27.12 MHz while
most semiconductor processing equipment operates at
13.56 MHz.
Examples:
• RF or High Frequency Heat Sealers
• Vinyl Welders
• Semiconductor Process Equipment
• Glass Deposition
• RF Induction Heating
• Dielectric Dryers and Heaters
• Plasma Generation Systems
RF energy can cause the body to be heated beyond its abil-
ity to thermally regulate itself. Since 1987 OSHA has had
the authority to cite employers for exceeding the limits spec-
ified by “state-of-the-art, scientific standards.” OSHA has
chosen the IEEE C95.1-2005 Standard for enforcement of
non-ionizing radiation safety. This IEEE standard includes
many changes from earlier standards and is considerably
more complex.
The Maximum Permissible Exposure (MPE) limits for Con-
trolled Environments are:

environment
Frequency E Field
(mW/cm2)
H Field
(mW/cm2)
13.56 MHz 4.89 54.4
27.12 MHz 1.22 13.6
40.68 MHz 1.00 6.04

1.3 About this operating manual
Characters and symbols used
Various elements are used in this operating manual to indi-
cate special meanings or particularly important passages in
the text.
Symbols and terms used in warnings
According to the American National Standard
ANSI Z535.6-2006, the following warnings, symbols, and
terms are used in this document:
Frequency f E Field
(V/m)

The general danger symbol warns of risk of serious injury
when used with the signal words CAUTION, WARNING,
and DANGER. Follow all the instructions in order to avoid
injuries or death.
NOTICE Indicates a danger that results in damage to or destruction
of the instrument.
CAUTION Indicates a hazardous situation which, if not avoided,
could result in minor or moderate injury.
WARNING Indicates a hazardous situation which, if not avoided,
could result in death or serious injury.
DANGER Indicates a hazardous situation which, if not avoided, will
result in death or serious injury.
