ICNIRP
= International exposure limit (a
complex formula
)
Salz 1
= Old Salzburg precautionary value (

)
Salz 2
= Salzburg precautionary value
outdoors
2002 (

)
Salz 3
= Salzburg precautionary value
indoors

In our fictional example, the bargraph display shows approximation to the inter-
national ICNIRP limit by 0,06%. As you can see, with this exposure limit, even a
relatively “strong” signal of -45dBm only generates a few
hundredth
of a per-
cent (namely 0,06%) of “deflection”. However, if you change to one of the Salz-
burg limits, the unit will quickly indicate even excess of the exposure limit.
When EXCEEDING a limit, the display shows percentages
above
100% (for
example 128,00 = excess of exposure limit by 28%). When the percentage is
greater than 999,99%, “***.**” is displayed. This means overflow.
HINT:
You can download
new and/or updated exposure limits
(which con-
stantly change!) from Aaronia’s homepage and keep SPECTRAN up-to-date at
any time. You should also check out our PC analysis software, which offers a
whole range of additional features.
Please note that the values in the graphic display can slightly change even if the
value at the main display is stable because SPECTRAN also uses the non visi-
ble fractions of the main display value to calculate the graphic display values.
One more alternative for finding the location of a signal source or for identifica-
tion / further processing of signals is the so-called Demodulation. Here, modula-
tion and pulsing of signal sources, if they exist, can be converted to sound and
thus become audible. SPECTRAN offers a special mode for this:
