Description 4-19

4.8 ICNIRP

The

International Commission on Non-Ionizing Radiation Protection

establishes guidelines for limiting EMF exposure that could affect human
health.

Standard section allows the user to select

standard ICNIRP limits

, already

included by the software installation.

When the

ICNIRP limit

is selected, the software automatically calculates

the corresponding total integration of the measured signals, and compares
the result with the threshold set by the standard, considering whether it is or
is not exceeded.

The calculation of the ICNIRP value is performed if

all three axes are

enabled
