4.2 Field probes
The SMP2 is a highly versatile EMF measurement
device that requires connection of the proper
eld probe to obtain the best results for each
application. Only Wavecontrol eld probes will
work with the device.
If the device is switched on with no eld probe
attached, it will not show any eld 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 eld
probe and its calibration parameters.
4.2.1 Connector type
There are two types of connector: push-pull and
screw.

• 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.
• Sampling mode: choice between a single
temporal log or several spatial measurements
that will be represented in a column graphical
chart.
• PostProcessing: this menu is only available
with broadband probes that have correction
factors in memory. It has 3 parameters:
• Enable correction: allows correction of
the value measured at a given frequency
(Working frequency dened below) using the
factors measured during the latest laboratory
calibration.
• Limit value for results in %: allows direct
reading of the eld as a % of a limit dened
on the main measurement screen. This is a
software calculation taking the limit value in
V/m and comparing it with the reading from
the probe. You can select the lower limit
(minimum value) of the regulation (within
the band width of the probe) or a specied
frequency (Working frequency dened below).
Note: If the minimum value is selected, no working
frequency can be dened and therefore the correction
factors cannot be activated.
• Working frequency: allows denition of the
working frequency for correction factors or
for calculation of the value as %. Where the
lower limit of the regulation is selected, this
parameter will show as “Not available”, since
it is not compatible with that selected mode.
The following parameters can be congured:
• Standard: List of preselected 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 dened by the standard.
• Measurement time: allows to dene 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
6.1.1). 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.

26.7671′ N 79° 58.9331′ W.
• Decimal degrees: example: +40.446 -79.982°.
• Turn on at start up: denes the GPS state when
the unit starts up.
• Turn on for current session: denes the GPS
state only for this session. That means that
next time you switch on the unit the GPS will
be in the state dened by “Turn on at start up”
parameter.
• Schedule measurement: allows to program
a scheduled measurement. A delay up to 24
hours can be set. Even with the unit is powered
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.
• 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 measurement 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.

User’s Manual
Electromagnetic Field Meter
This section describes the main functions of the
SMP2, in addition to instantaneous measurement
of the electromagnetic eld.
6.1 Measurement modes
There are several working modes for the SMP2.
All probes have the temporal mode with spatial
average. Only the WP400 has the FFT mode and
the Frequency Log mode. For this last probe, in
the main screen you can see the “Mode” function
that allows to switch between modes.
Modes are:
• Temporal: it records the evolution of the total
eld value. For more details see 6.1.1
• FFT (only available for the WP400): it records
the frequency information of the eld. For more
details see 6.1.2
• Frequency Log: it records the evolution of the
eld but only at one frequency of interest. For
more details see 6.1.3
6.1.1 Temporal mode - time domain
measurements
One of the functions of the SMP2 is the storage
of measurements in memory for later study
or processing. Measurements in time domain
contain eld samples, one sample every “log
interval” as dened in 5.4. For example, a 6
minutes measurement at 0.5s log interval will
create a 720 samples measurement.
6. Functions
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
measurements is 1000.
Before starting the measurement, the parameters
for the measurement time, type of average and
average interval should be congured via the
Measurement Options menu (see 5.4). The eld
and average eld values will be stored in the unit
selected in the main screen.
To start logging samples, go to 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 SMP2 can not be
changed.
In order to store positioning information along with the
eld values, the GPS receiver should be enabled before
logging is started.
6.1.1.1 Measurements according to ICNIRP
procedures
The ICNIRP procedure set-up is the most widely
referenced by international standards.
