Compliance Level Electromagnetic Environment — Guidance
Portable and mobile RF communications
equipment should be used no closer to any part of
the Smart Scale, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency of
the transmitter.
Conducted RF
IEC 61000-4-6
3 Vrms
150 kHz to 80 MHz
3 V Recommended separation distance:
Radiated RF
IEC 61000-4-3
3 V/m
80 MHz to 2.5 GHz
1 V/m 80 MHz to 800 MHz
800 MHz to 2.5 GHz
...where (
P
) is the maximum output power rating
of the transmitter in watts (W) according to the
transmitter manufacturer and (
d
) is the
recommended separation distance in meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
1
should be less than the compliance level in each
frequency range.
2
Interference may occur in the vicinity of
equipment marked with the following symbol:
1. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios,
amateur radio, AM and FM broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the
electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured
field strength in the location in which the Smart Scale is used exceeds the applicable RF compliance level above, the Smart
Scale should be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the Smart Scale.
2. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
NOTE
#
„
At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
„
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects, and people.
