Wavecontrol SMP2. Congratulations for your acquisition of a This manual provides you with instructions for using and handling your SMP2. Please read this Manual carefully before using your SMP2. WARNINGS AND PRECAUTIONS Review this manual and become familiar with all the instructions for using and handling your SMP2. -
Page 4: Introduction
INTRODUCTION 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. -

Page 8: Field Probes
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. -
Page 9: Push-Pull Connector
A USB to mini USB cable is delivered with the SMP2. After installing the SMP2 software (First install the software see 8.1) 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. -

(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 SMP2 measurement contains 401 frequency points so the memory of the allows storage of up to 1000 frequency measurement. -
Page 17: Scenarios
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. -
