1Useful information
This chapter contains basic information about measuring electromagnetic
elds, about using the Nardalert S3, and about the structure of this
Operating Manual.
1.1 Measuring electromagnetic elds
1.2 About this monitor
1.3 About this Operating Manual
1.1 Measuring electromagnetic elds
In today’s world, many industries utilize equipment that generates elec-
tromagnetic elds. Our modern need for communications as well as the
eciency of electromagnetic heating systems and the safety that radar
systems provide us are just a sample of the applications that are benetted
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 dened
limit values designed to protect users from the dangers of exposure to
such emissions, and the Nardalert S3 is an eective 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 50 Hz 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

Narda8 Nardalert S3
1 Useful information
casing, long battery life, and high measurement accuracy. The NS3 features
multiple types of sensors to accurately monitor human exposures while
worn on the body. It can be used o the body to detect elds also. Sensors
for various monitoring applications are connected to the NS3 basic unit.
Flat frequency response sensors are (or are planned to be) available, as
well as shaped sensors that evaluate the eld according to a specic
human safety standard. 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 congure and remote control the NS3, as well
as to export saved measurement data and to analyze the results (if unit is
congured for that option).
Applications
The NS3 performs measurements for human safety purposes, particularly
in workplace environments where high electric or magnetic eld strengths
are likely. It can also be congured to function as a stand-alone area
monitor with or without the Narda NBM-580 multiple-channel metering
station.
Examples:
•Monitoring human exposure eld strengths as part of general safety
regulations
•Monitoring the eld strengths around transmitting and radar equip-
ment to establish safety zones and for monitoring personnel during
operations
•Monitoring the eld strength emanating from mobile phone base sta-
tions and satellite communications systems to ensure compliance with
human safety limit values
•Monitoring operator exposures in the industrial workplace environ-
ment, such as around plastic welding equipment, RF heating, temper-
ing, or drying equipment
•Monitoring to ensure the safety of persons using diathermy equip-
ment and other medical equipment that generates high frequency
radiation
•Field strength monitoring in TEM cells, absorber chambers or test
ranges

!Remember that eld levels will rapidly increase as you approach the
source of the emission.
!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 eld
level displayed when you are approaching an unknown eld source.
2.4 Dangers from electromagnetic elds
Strong elds
Very high eld strengths can occur in the vicinity of some radiation
sources.
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.
Do not cross or ignore safety barriers or markings.
Persons with implanted electronic medical devices
(e.g. heart pacemakers) must avoid restricted areas.
Measurement errors
Metallic labels (stickers) axed to the black sensor area of the sensor can
lead to measurement errors, usually an underestimation of the electro-
magnetic eld strength.
Ax labels of any type only to the yellow housing. Metallic labels must
be axed to the rear of the monitor.
If the instrument malfunctions, take it out of service and contact your
Narda Service Center. The addresses are listed at the end of this Oper-
ating Manual and on the Internet at www.narda-sts.com.

2.5 Dangers from AC mains charger
Sensor is not installed or operating properly
The NS3 is designed to monitor the presence of the sensor and that the
sensor is functional.
Ensure that the sensor is attached properly to the basic unit. Sensor
is designed to be even with the surface of the basic unit and to pass a
functional test at turn-on. If in doubt, cycle unit o and then on again
to perform connection test. If the sensor is defective, not installed or
failing pre-test, it will cause the system to not proceed to measure-
ment mode.
Condence testing of RF/microwave sensors can be accomplished with
a simple 2-way radio that generates more than 1 Watt. An upscale indi-
cation should be noticed on the display when the radio is transmitting
close to the sensor housing. Narda oers portable sources to accom-
plish this important test (see Optional Accessories on page 44).
Before beginning any RF radiation measurement, always inform your-
self of the frequencies and eld strengths that you could be expected
to encounter.
2.5 Dangers from AC mains charger
You could experience electric shock from the external power supply.
Do not open the charger as there are no user serviceable parts inside.
Do not expose or submerse the charger in water at any time. It is de-
signed to be used in an indoor, protected environment.
Only use appropriate USB adapter cords. Never use a damaged USB
cord.
Only supply AC voltage that meets the voltage specied at the AC
input on the Charger. The AC mains charger could be destroyed if
the voltage specication of the charger does not match the AC line
voltage.

3 Preparing the Nardalert S3 for use
to perform connection test. If the sensor is defective, not installed or
failing pre-test, it will cause the system to not proceed to measure-
ment mode.
Charging of the monitor is accomplished by attaching the proper AC
mains plug to the charger and then the supplied USB cable to the
charger and NS3. The unit will be rapidly charged when using the
supplied USB charger and at a slower rate (longer time) if plugged into
a computer. Charging time is approximately 4 hours for a full charge.
Note the battery Icon in the top right of the display when the unit is
energized, indicating the amount of charge.
Condence testing of RF/microwave sensors can be accomplished
with a simple 2-way radio that generates more than 1 Watt. An upscale
indication should be noticed on the display when the radio is transmit-
ting close to the sensor housing. The NS3 provides a menu screen "Self
Test", to evaluate the output from the three detectors used in the RF/
microwave sensors.
Before beginning any RF radiation measurement, always try to verify
the frequencies and eld strengths that you could be expected to
encounter.
There are many dierent sensors available for dierent applications and
use with the NS3. You can nd more information about the order numbers
and specications of the sensors under Ordering Information on page
43, as well as in the data sheets of the NS3. These documents can also be
downloaded from the Narda website on the internet at:
www.narda-sts.com.
Wrong handling of the sensor
Damage of the sensor antennas
Always try to store the sensor in the carrying case when not installed
in the NS3. This should help protect it from excessive shock and vibra-
tion, as well as environmental extremes.
