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:

Table 1 IEEE C95.1-2005 exposure limits for controlled

environment

Frequency E Field

(mW/cm2)

H Field

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)

H Field

(A/m)

1 - 10 MHz 610 / f (f in MHz) 1.6 / f (f in MHz)

10 - 400 MHz 61 0.16

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.
