1 Useful information

This chapter contains basic information about measuring electromag-

netic fields, about using the Nardalert S3, and about the structure of this

Operating Manual.

1.1 Measuring electromagnetic fields

1.2 About this monitor

1.3 About this Operating Manual

1.1 Measuring electromagnetic fields

In today’s world, many industries utilize equipment that generates

electromagnetic fields. Our modern need for communications as well as

the efficiency of electromagnetic heating systems and the safety that

radar systems provide us are just a sample of the applications that are

benefitted by exploitation of the electromagnetic spectrum. We also have

various engineering considerations as well as regulatory requirements to

use the electromagnetic spectrum wisely. Various authorities have long

defined limit values designed to protect users from the dangers of

exposure to such emissions, and the Nardalert S3 is an effective tool to

help companies and individuals demonstrate compliance.

1.2 About this monitor

The Nardalert S3 (“NS3”) provides virtually everyone concerned with this

subject with an instrument for monitoring non-ionizing radiation that a

body might be exposed to within the frequency range from 100 kHz to

100 GHz (depending on the sensor used). The NS3 has a wide range of

functions, yet it is very easy to use. It also features a handy design,

robust casing, long battery life, and high measurement accuracy.

1Useful information

6 Nardalert S3

The NS3 features multiple types of sensors to accurately monitor human

exposures while worn on the body. It can be used off the body to detect

fields also. Shaped sensors that evaluate the field according to a specific

human safety standard are connected to the NS3 basic unit. These

sensors are calibrated separately from the basic unit and include a non-

volatile memory containing the sensor parameters and calibration data.

They can therefore be used with any NS3 without any loss in calibration

accuracy. The PC software supplied with the monitor allows you to

configure and remote control the NS3, as well as to export saved

measurement data and to analyze the results (if unit is configured for

that option).

Applications

The NS3 performs measurements for human safety purposes,

particularly in workplace environments where high electric or magnetic

field strengths are likely. It can also be configured to function as a stand-

alone area monitor.

Examples:

•

Monitoring human exposure field strengths as part of general safety

regulations

•

Monitoring the field strengths around transmitting and radar

equipment to establish safety zones and for monitoring personnel

during operations

•

Monitoring the field strength emanating from mobile phone base

stations and satellite communications systems to ensure compliance

with human safety limit values

•

Monitoring operator exposures in the industrial workplace

environment, such as around plastic welding equipment, RF heating,

tempering, or drying equipment

•

Monitoring to ensure the safety of persons using diathermy

equipment and other medical equipment that generates high

frequency radiation

•

Field strength monitoring in TEM cells, absorber chambers or test

ranges

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.

2 Safety instructions

This chapter contains important instructions on how to use the Nardalert

S3 safely. Therefore, please read this chapter carefully and follow the

instructions closely.

2.1 Using this Operating Manual

2.2 Intended use

2.3 Dangers from electromagnetic fields

2.4 Dangers from AC mains charger

2.1 Using this Operating Manual

! Carefully read this entire Operating Manual before you start using

the instrument.

! Keep this Operating Manual so that it is available to everyone who

uses the instrument, and ensure that this Operating Manual is with

the instrument if you pass it on to a third party.

2.2 Intended use

! The NS3 is a warning device that gives active notice of the

existence of dangerous fields by means of a visible and audible

warning signal.

! Only use the instrument for the purpose and under the conditions for

which it has been designed.

2Safety instructions

10 Nardalert S3

! In particular, observe the technical data given in the Specifications

on pages 33-34. Proper use also includes:

! Observing any national accident prevention regulations at the

place of use.

! Ensuring that the instrument is used only by appropriately

qualified and trained persons.

! If you remove the unit from your body, it is important that the back of

the unit faces your hand (body) especially at microwave

frequencies. When you remove unit from body, carefully observe the

actual field level displayed when you are approaching an unknown

field source.

2.3 Dangers from electromagnetic fields

⚠WARNING

Strong electromagnetic fields

Very strong electromagnetic fields occur near

many radiation sources.

Observe safety barriers and markings.

In particular, persons with electronic implants must

keep away from dangerous areas.

This monitor is designed to be directional at

microwave frequencies. It cannot warn you about a

microwave exposure behind you if the monitor is

worn on the front of the body.

Measurement errors

Metallic labels (stickers) affixed to the black sensor area of the sensor

can lead to measurement errors, usually an underestimation of the

electromagnetic field strength.

Affix labels of any type only to the yellow housing. Metallic labels

must be affixed to the rear of the monitor.

If the instrument malfunctions, take it out of service and contact your

Narda Sales Partner. The addresses are listed on the Internet at

www.narda-sts.com.
