2 INTRODUCTION
The SMP2 Portable Electromagnetic Field Monitoring System can measure electromagnetic field
levels generated by any source within the frequency range of the probe attached to the system.
It combines 2 instruments in 1: Broadband measurements and selective measurements (FFT),
including % direct EMF exposure assessments to limit lines by using the weighted peak exposure
(WPE) technique.
The SMP2 has been developed to meet demanding customer requirements in the RF safety
measurements domain. Its versatility makes it a perfect measurement tool for many different
sectors and industries such as Railway, Power, Manufacturing, Chemical, Medical, Defence, RFID
and EAS, Telecommunications, etc.
Those measurements can be made quickly and easily anywhere because the SMP2 is portable
and simple to handle and use.
The SMP2 can sample the field level continuously and store that data automatically in its built-in
memory at user-configured intervals with a capacity of up to 1 000 000 samples.
The data stored in the memory can be easily downloaded to a computer via a USB or fiber optics
port for later processing.
The SMP2 is also available with a built-in GPS receiver to allow each measurement to be
associated automatically with the geographic location where it was taken.

4.2 Field probes
The SMP2 is a highly versatile EMF measurement device that requires connection of the proper
field probe to obtain the best results for each application. Only Wavecontrol field probes will
work with the device.
If the device is switched on with no field probe attached, it will not show any field value and
therefore no measurement will be saved to memory. However, saved data and GPS positioning
functions will be available.
The SMP2 automatically detects the type of field probe and its calibration parameters.
.2.1 Connector type
There are two types of connector: push-pull and screw.
Figure 5: Screw connector Figure 6: Push-pull connector

4.2.3.1 How to connect the push-pull probe
With a push-pull connector, the field probe is connected by inserting the male connector into the
female connector of the SMP2 until it stops. The polarity of the connector must be observed and
so the red marks on the male and female connectors must line up.
Figure 8: How to connect the field probe
4.2.3.2 How to disconnect the field probe
You do not need to switch the device off before you disconnect the field probe. Pull the
connector of the probe firmly with one hand (pulling with the thumb) while you hold the SMP2
with your other hand as shown in the pictures below:
Figure 9: How to disconnect the field probe
Important: Pull the connector. Don't pull any other part of the probe!
Don't try to twist or unscrew the probe.
4.3 External connections
.3.1 USB
A USB to mini USB cable is delivered with the SMP2. After installing the SMP2 software (First
install the software see .1) just plug the cable to the SMP2 and to the computer. You will be
able to download stored measurements to the computer or update the SMP2 firmware.
Note: it is not recommended to perform measurements while the USB is connected, it could affect the
quality of the readings.

5.4 easurement configuration screen
This screen is used to configure different parameters related to measurement behaviour. It
appears as a menu with a scrolling bar. The parameters to be configured are shown on the left
and the different options for each parameter are shown on the right.
The keypad is used to move along the menu. The process for changing the value of a parameter
is:
-Run through the different parameters using the arrows  .
-To change a parameter, press Enter when the cursor is on that parameter. A pop-up will
appear showing all the possible values.
-Run through the different values using the arrows   and click on OK to select the desired
value. (you can cancel with the back button)
-When finished you can either press again back to return
to the menu screen or press the home button to come
back to the main screen
The following parameters can be configured:
Standard: List of preselect standards. This will affect
other parameters that will not be editable. For
example: if you choose ICNIRP standard then all the
parameters in “Measurement behaviour” will not be
editable as they are defined by the standard.
Measurement time: allows to define a maximum
time for the measurement. Available values are: Not
limited, 1min, 5min, 6min, 10min, 15min, 30min,
1h, 2h, or custom from 1sec to 100 hours.
Log interval: used to select the time interval for
storage of data in memory (see section 6.1). A datum
will be stored every ‘Log interval’ seconds (or minutes).
The available intervals are 0.5s, 1s, 5s, 10s, 15s, 30s, 1min and 6min.
Average type: two types of average are available: arithmetic (a new average is
calculated every average interval) , sliding (a new average is calculated every new sample)
Average interval: used to select the time interval for calculation of the average. The
available intervals are 10s, 15s, 30s, 1min, 2min, 5min, 6min, 10min, 15min and
30min.
Schedule measurement: allows to program a scheduled measurement. A delay up to 24
hours can be set. Even with the unit power off, this feature works.
Wait time before start: delay before the measurement really starts (it allows the
technician to separate himself from the equipment. Available values are No delay, 5s,
10s, 15s, 20s, 30s, 1min.
Shut down after measurement: useful option to power off the unit when
measurement is done. It avoids having to wait to power off the unit manually.
- 13 -

Screenshot on last sample: when this is activated it will allow to take a screenshot on
the last measurement. When using for example the ICNIRP standard it will allow to have
an image with the 6 min average results. This image will be available to be exported
directly into the report with the SMP2 software.
Save measure name: permits to save a name for each measurement. In case it is
activated, a pop-up will appear before the measurement starts in order to indicate a
name.
Delete all measurement: will delete all measurements as well as all the screenshots
related to these measurements. Depending on the number of data in memory this
operation may last some time. It is recommended to use this function from time to time in
order to free space for new measurements.
5.5 easurement log screen
This simple screen will show all available measurements. The arrows   are used to select
the next or previous measurement. The arrows   are used to select the next or previous
measurement located in the next page.
From this menu you can use the virtual button “view” to view a specific measurement (can be
done by clicking on OK), “delete” to delete a single measurement or “delete all measurements”
to erase all data in memory (the last action does the same as the “Delete all measurements” in
the Measurement configuration screen.
5.6 GPS screen
This screen has the same layout and behavior as the measurement configuration screen. It allows
to modify the GPS parameters. Those parameters are:
Format: allows to select 3 standard format for the latitude and longitude. You can
choose between:
• degrees minutes seconds: example: 40° 26 46 N′ ″ 79° 5 56 W′ ″
• degrees decimal minutes: example: 40° 26.7671 N′ 79° 5 .9331 W′
• decimal degrees: example: +40.446 -79.9 2°
Turn on at start up: defines the GPS state when the unit starts up.
Turn on for current session: defines the GPS state only for this session. That means that
next time you switch on the unit the GPS will be in the state defined by “Turn on at start
up” parameter.
5.7 Settings screen
This screen has the same layout and behavior as the measurement configuration screen. It allows
to modify the general parameters of the SMP2.
The following parameters can be configured:
Alarm: allows to activate or deactivate the alarm. When activated, you can define the
alarm threshold and unit for electric and magnetic field. (the   arrows are used to
select the figure to be changed and the   arrows are used to change the figure value.)
Date: allows to change the date of the system
Time: allows to change the time of the system
- 14 -

Zero based time plots. Allow to scale the graph between 0 and the maximum of the

more information about the unit like disk space available.
6 FUNCTIONS
This section describes the main functions of the SMP2, in addition to instantaneous
measurement of the electromagnetic field.
6.1 Broadband - time domain measurements
One of the main functions of the SMP2 is the storage of measurements in memory for later
study or processing. Measurements in time domain contain field samples, one sample every “log
interval” as defined in 5.4. For example a 6 minutes measurement at 0.5s sampling interval will
create a 720 samples measurement.
Measurements are stored in a SQL database. The memory of the SMP2 allows storage of up to
1,000,000 samples. The maximum number of measurement is 1000.
Before starting the measurement, the parameters for the measurement interval, type of average
and average interval should be configured via the measurement configuration menu (see 5.4).
The field and average field values will be stored in the unit selected in the main screen.
To start logging samples, go in the main screen (direct access is always available by pressing the
home button) and press the “log” function. When logging starts, the device automatically
creates a new measurement with its starting date.
To stop logging samples, press the “stop function”.
Note: If the storage limit of the memory is reached, the logging of samples will be automatically
stopped
During logging parameters of the SM 2 can not be changed.
In order to store positioning information along with the field values, the GPS receiver should be
enabled before logging is started.
6.1.1 Measurements according to ICNIRP procedures
ICNIRP procedure set-up is the most widely referenced by international standards.
- 15 -

That measurement allows an average to be taken of the field values measured over 6 minutes at
a given place without the presence of the technician affecting the result.
To perform this type of measurement select ICNIRP in the configuration measurement screen. All
the parameters will be forced to the pre-defined value:
1. The apparatus will wait 10s before starting the measurement to allow the technician to
move away. After the 10s, a beep will indicate the start of the measurement.
2. It will log samples for six minutes.
3. At the end of the 6 minutes, the measurement will be stopped automatically and the
alarm will sound. The apparatus will calculate the average, display it on the screen and
store it in memory.
This measurement can be cancelled at any time by pressing the STOP function.
6.1.2 Low frequency time domain measurement with WP50 or WP 00
When using this probes, additional functions are available other than those explained in 5.4
•Mode: select frequency or time domain mode (only available for WP400)
•Field: select electric or magnetic field
•Limit: (see 6.3) select the standard to apply
◦None. No weighting will be applied and the measurement will be displayed in the
desired units.
◦Other choice (measurement will be weighted in % compared to the chosen limit)
6.2 Selective - frequency domain measurements
This function is only available with a selective probe like WP400. When using such probe you can
decide in the main screen whether you want to work in the time or frequency domain using the
function “Mode”.
•In time domain mode you can refer to section 6.1 as it works the same way as a
broadband probe. The only additional value you will have using the WP400 is the peak
value.
•In frequency mode you will have, in the main screen, the graph representing the
frequency information (FFT) for the selected SPAN and the total field value representing
the RMS value. (Span has no effect on the total field value)
Measurements in frequency domain contain frequency information of the measured field. One
measurement contains 401 frequency points so the memory of the SMP2 allows storage of up
to 1000 frequency measurement.
In frequency mode the parameters in “measurement configuration” have no effect. All
parameters have to be chosen from the functions in the main screen:
•Mode: select the frequency or temporal mode
•Field: select electric or magnetic field
•Span: select the frequency range (only affects the FFT):
◦0 - 400 Hz (1 Hz resolution)
◦0 - 4 kHz (10 Hz resolution)
◦0 - 40 kHz (100 Hz resolution)
- 16 -

◦0 - 400 kHz (1 kHz resolution)
•Limit: (see 6.3) select the standard to apply
◦None. No weighting will be applied and the measurement will be displayed in the
desired units.
◦Other choice (measurement will be weighted in % compared to the chosen limit)
•Hold
◦Off. No Maxhold is applied. Real-time value is displayed on the screen and FFT is
update with new values every half second
◦Max. Maxhold is applied. Peak value, RMS value and FTT will keep only the max
value. This option is the best when you want to make a single measurement for
compliance with a limit. Activate the MaxHold, wait the desired time and press log to
save the maximum Peak value, RMS value and FTT in a single register.
•Axis (useful for direction finding application)
◦T. Total value of the FFT
◦X axis of the FTT
◦Y axis of the FFT
◦Z axis of the FFT
Note: When downloaded to the PC, all axis of FFT measurements can be seen on the
graph.
To save a FFT, go to the main screen (direct access is always available by pressing the home
button) and press the “log” function. The device will save the current FFT.
6.2.1 Scenarios
This paragraph intents to give you some recommendations on how to use this selective system
for several situations:
•Checking power lines harmonic content:
•Select mode: frequency domain
•Span: 400 Hz
•Filter: 10 Hz
You will get an FFT showing the 50 Hz and its main harmonics in the frequency domain
(from 1 to 400 Hz). Repeat this for electric and magnetic field.
•Power lines measurement:
•Select mode: temporal
•Filter: 10 Hz.
In this mode you will get a temporal recording of the total value like a broadband probe.
Repeat this for electric and magnetic field
•Measurements where field type is unknown:
•we recommend to always use at least the filter 10Hz because below 10 Hz any
non desired movement around the unit may affect the measurement. If you are
not sure if there is field below 10 Hz, then put the filter to 1 Hz. In this case
always measure with the SMP2 on a tripod and the fibre link in order to avoid
any external perturbation.
- 17 -

•if you need only to see the compliance in % respect to a standard, temporal
mode is enough. This will give you a complete and instantaneous result to
compare with the standard
•If you need to check the frequency content of the field, then use frequency
mode. First use the higher span. If no field is detected above 40 kHz then change
span to 40 kHz. Then if no field is detected above 4kHz then change span to 4
kHz. Then again if no field is detected above 400Hz, change to the lowest span
that is 400 Hz. When you have the desired span you can save the FFT by pressing
the log function.
Note: even in frequency mode, total field value, axes values, max, min and pea value are updated
every 0.5 seconds and represent the field value in all the frequency range.
6.3 Time domain weighting
Some probes like WP50 and WP400 can assess the RF exposure by directly comparing the field to
a reference limit. It uses the Weighting Peak Exposure technique that weights the field with a
filter function which is related to the reference level.
The result is a number in % where 100% represents the reference limit line. More than 100%
will mean that the present field is exceeding the limit specified by the chosen standard.
Note: This function is available for time and frequency domain measurement and the results will be
displayed in % instead of the electric or magnetic corresponding units.
6.4 Alarm
The alarm function is very useful for the technician who makes the measurements because it
allows the apparatus to give an audible warning when the field exceeds a threshold value
defined on the settings screen. The alarm will only sound if the alarm function has been
activated and if the sound is enabled in the Settings screen.
6.5 GPS
The SMP2 is available with a built-in latest-generation GPS ublox engine 7 allowing you to
display and memorise the position of the device when taking measurements. The incorporation
of ublox functions makes the receiver extremely sensitive and precise, allowing exact positioning
even in built-up areas with poor satellite visibility.
The GPS is enabled/disabled through the configuration menu as explained in section 5.6.
When the position obtained by the GPS is not valid, the main screen displays ‘Searching for
satellites’. When the position obtained by the receiver is valid, the data for latitude, longitude are

7 BATTERY INFORMATION
7.1 General information
The SMP2 contains a rechargeable Li-ion battery allowing the apparatus to run for over 15 hours
with broadband probes and over 4h30 for selective probe like WP400. The level of battery
charge can be checked at any time on the main screen of the apparatus, in the battery field.
Li-ion batteries have no “memory effect” and so there is no need to fully discharge the battery. It
is recommended to charge completely the battery before the first use.
Always switch the apparatus off when it is not in use.
Recharge the battery regularly (for example, once every 2 months) if the apparatus
goes for long periods without being used.
The battery of the SMP2 should be recharged when the battery indicator shows that it is at its
minimum level:
Although the apparatus can be fully used while the battery is being charged we
do not recommend to measure with the charger connected as mains perturbation
may alter measurement. In general measurement has to be done without the
charger or USB connected.
The battery will function normally at temperatures ranging from -20ºC to +45ºC. However, we
recommend avoiding low temperatures to prevent its useful life from being shortened.
Only the battery charger supplied by Wavecontrol should be used to recharge the battery of
the SMP2.
7.2 Recharging
The battery charge time is –5 hours. We recommend to turn off the SMP2 for charging the
battery. The procedure for charging the battery is:
• Plug the charger into an electrical outlet (110-240 V AC).
• Insert the connector of the battery charger into the connector of the SMP2. The
recharge red LED will light up. If it does not light up, it means that the charger is not
properly connected.
• The charge is complete when the recharge LED is green. Disconnect the charger from
the SMP2 and unplug it from the mains.
The SMP2 has a Li-ion battery charge controller so you can leave the apparatus charging for
more than the specified 5 hours with no danger of damaging the battery.
Note: it is recommended to do a complete charge from time to time for SMP2 to recalibrate the battery
capacity.
Note2: if during the charging, the red light blin s this means the battery is too hot or is not charging
properly. Disconnect the charger and wait at least 1 hour, connect the charger bac : in case this
happens again battery may be bro en.
