1 Introduction
This chapter contains a short introduction about measuring
electromagnetic fields, about using the SMARTS II, 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 SMARTS II is an effective tool to
help companies and individuals demonstrate compliance.
1.2 About this monitor
The SMARTS II area monitors provide continuous detection of RF
radiation within a specific area. The SMARTS II uses ultra-wideband
sensor technology. The result is an area monitor that covers most of the
usable RF spectrum in a single monitor with shaped frequency response
that matches the safety standard used to determine compliance. The
dual sensor design detects all types of electric fields from 2 MHz to 100
GHz. The microwave portion of the sensor employs thermocouple
detectors so that radar signals are accurately converted to true RMS
values while the diode design used for the lower frequencies provides
RMS detection even in very complex, multi-signal environments.
SMARTS II monitors respond equally to all polarizations and cover an

1Introduction

entire hemisphere. They can even be mounted on a metallic wall. There
is a SMARTS II model shaped to match most of the major safety
standards.
The SMARTS II operates from a 9-volt lithium Ultralife battery (U9VL) or
an external +12 V to +24 V (Floating) supply. Every monitor has an
audible and visual alarm indication. An alarm condition causes a voltage
transition (-4/+4 V) to occur at the STATUS jack. When the SMARTS II
is operated from an external power supply, you have the option to use
the contacts of an SPDT (Single Pole Double Throw) relay to indicate
alarm status. The status relay cannot be used under battery operation.
Either the voltage transition signal or the relay contacts can be used to
provide remote alarms, a record of alarm conditions, and/or automatic
shutoff of equipment.
Applications
The SMARTS II performs measurements for human safety purposes,
particularly in workplace environments where high electric or magnetic
field strengths are likely.
The SMARTS II is an area monitor that can be installed on ceilings and
walls, with automatic frequency response evaluation according to a
selected safety standard. SMARTS II emits warning sounds if user
settable thresholds are exceeded. SMARTS II is ideal for security
installations in aircraft hangars or military facilities, thanks to its
frequency range from 2 MHz to 100 GHz and measurement range of up
to 3000% of the limit value of the chosen safety standard.

Incorrect mains voltage, condensation, high or low temperatures and
insufficient ventilation can damage a power supply.
! Check before the connection of the power supply that its
operating voltage matches the mains voltage.
! Do not use a power supply with condensation. If
condensation cannot be avoided, e.g. because the power
supply is cold and is brought into a warm room, it must be
dry before establishing a connection.
! Only use the power supply indoors, and within the specified
temperature range (see datasheet for the power supply).
2.7 Batteries
Impermissible environmental conditions
Too high temperatures and humidity can lead to a short circuit and
cause a fire. This may result in personal injury or destruction of the
batteries.
 Check regularly whether the storage temperature and humidity are
within the specified limits. Information on the limits can be found in
the datasheet for the U9VL battery.
 Do not leave discharged batteries in the device for long periods of
time. The housing can also be damaged from the inside through
leaking electrolyte.
 When storing the batteries, make sure that they do not come into
contact with metallic objects.
Improper handling of batteries
Improper handling of batteries can cause personal injury and damage to
the device or the batteries.
! Do not open, crush or disassemble batteries.
! Do not drop batteries from a great height.

2Preparing the SMARTS II for use
16 SMARTS II
! Do not solder anything to batteries.
Use and replacement of batteries
Improper replacement of batteries may result in injury and damage to
the device or the batteries.
! Only operate the device with the permitted batteries (see
1.2 About this monitor or refer to the datasheet for
information on the permissible types).
! Never short-circuit the contacts of the batteries, i.e. never
touch both terminals with metal parts at the same time.
! Observe the polarity of the snap connector and insert the
batteries accordingly.
! Always close the battery compartment immediately after
replacement, and never operate the device with the battery
compartment open.
Combustion of the batteries
Through an incorrect use it is possible that the batteries could ignite.
This can cause injuries and damage to the batteries.
! To prevent the batteries from igniting, do not expose the
batteries to high temperatures for long periods of time.
! If the anode or cathode of the batteries comes into contact
with another metal, heat may develop and the electrolyte
may leak. The electrolyte is flammable. If the electrolyte has
leaked, the batteries must be immediately removed from the
vicinity of a fire.
! If batteries burn, irritation may occur in the eyes, skin and
respiratory tract as a result of developing smoke or vapors
(see next section).
Dangerous emitted substances
Under normal handling conditions, no dangerous substances will escape
from the batteries, and thus no contact with toxic substances can occur.
The only danger of leakage is from mechanical damage to the housing.
If chemicals should escape, the following must be observed:
! Emitted gases (from fire or mechanical damage) can cause
respiratory problems. In case of an emergency, see a doctor
immediately.
! Skin irritation may occur if the skin comes into contact with
chemicals. Wash the skin thoroughly with soap and water.
! Irritation of the eyes may occur. Immediately wash the eyes
thoroughly with water and seek medical attention.

3.1 Test button
The TEST button provides a means to test most of the monitor circuitry.
Briefly pressing the TEST button simulates an alarm condition. The
audible and visual indications will warn as long as the user is pressing
the TEST button.
3.2 Alarm indications
Audible
The audible alarm is sufficiently loud for most indoor applications. An
external alarm indication, audible and/or visual, is recommended when
the SMARTS II is located in an area with significant ambient noise.
When the SMARTS II detects radiation at its preset alarm threshold or
higher, a continuous audible alarm is generated.
Visual (LED indicator)
The red LED indicator flashes approximately every forty seconds
whenever the SMARTS II is functioning normally.
When the SMARTS II detects radiation at its preset alarm threshold or
higher, the LED indicator flashes for 10 ms every second.

Alarm indication overview
3.3 Sensor
The SMARTS II detects all types of electric fields from 2 MHz to 100
GHz. The monitor uses a dual sensor design. The microwave portion of
each sensor employs thermocouple detectors so that radar signals are
accurately converted to true RMS values while the diode design used for
the lower frequencies provides RMS detection even in very complex,
multi-signal environments. The output of the high frequency sensors is
combined and fed to a low-noise amplifier circuit. Similarly, the output of
the low frequency sensors is combined and fed to another low-noise
amplifier.
The output of these two amplifier circuits is scaled in terms of percent of
the respective human safety standard. The sum of these two amplifier
levels is used to determine whether the monitor is above or below the
alarm threshold that has been selected by the user. SMARTS II respond
equally to all polarizations and cover an entire hemisphere.
3.4 Battery compartment
Removing the cover that is attached with four captive screws accesses
the battery compartment. The cover has an RFI (Radio Frequency
Interference) gasket to ensure that the internal circuits remain isolated
from strong electromagnetic fields.
The U9VL battery can be inserted in the battery compartment. The
BATT–PS (battery–power supply) switch and a two-section Alarm
Threshold DIP switch are also located within the battery compartment.

Inside battery compartment:
3.5 Input/output connector
All input and output connections are made via a single, 9-pin D-
subminiature male connector located on the top side of the SMARTS II.
A mating connector is supplied with the monitor. This input/output
connector is used to provide connections for:
 Relay contacts (N.C., COM., and N.O.)
 ENABLE/RECORDER
 STATUS (voltage transition signal, -4 V/+4 V)
 External +12 V to +24 V floating power
The input/output connector is filtered to protect the SMARTS II from
strong electromagnetic fields. However, a shielded cable is highly
recommended.
