Detection of high-frequency (HF) fields and identification of the radiation sources by an acoustic signal proportional to the frequency
strength
(electromagnetic waves generated by mobile phone masts, Wifi/WiMax or cordless phones (DECT), smart home devices,
smartwatches, etc.).
1.
To switch on the appliance, briefly press the On-Off button.
2.
Hold the device away from the body with an outstretched arm.
3.
Move the device slowly in the environment to detect surrounding electromagnetic fields (the device starts a new detection phase every 2
seconds).
The following table gives corresponding numerical values of the detected high frequencies (HF)
LEDs) (Frequency range: 1 MHz - 10 GHz) Values in µW/m² (microwatt/m²).
Levels
High frequencies [µW/m²]
CEMPROTEC
Levels
High frequencies [µW/m²]
CEMPROTEC
* Measured peak value. The values of individual devices may vary slightly compared to the table values given, due to tolerance of individual electronic components. The limits of
exposure depend on individual sensitivities. The measured values are indicative and are not the responsibility of EPE Conseil.
Diagram for measuring high frequencies
Indicative measure of radiation strength for radio frequencies (RF) in volts per metre (V/m) and microwatts per square metre (µW/m²), depending on the
colour of LED switched on. The threshold values given are recommendations and standards and are taken from appropriate sources (see below).
