Guidance and manufacturer's declaration – electromagnetic immunity
OMRON Digital Weight Scale is intended for use in the electromagnetic environment specified
below. The customer or the user of this OMRON Digital Weight Scale should assure that it is
used in such environment.
Immunity test
Conducted RF IEC
61000-4-6
Radiated RF IEC
61000-4-3
Note1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note2: These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects, and people.
IEC 60601 Compliance
Test level level
3 V rms Not Applicable.
150 kHz to
80 MHz
3 V/m 3 V/m
80 MHz to
2.5 GHz
Electromagnetic environment – guidance
Portable and mobile RF communications
equipment should be used no closer to any
part of the OMRON Digital Weight Scale
including cables, than the recommended
separation distance calculated from the equation
appropriate to the frequency of the transmitter.
Recommend separation distance
Not Applicable.
d = 1.2 √P
80 MHz to 800 MHz
d = 2.3 √P
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,
should be less than the compliance level in each
b
frequency range.
Interference may occur in the vicinity of
equipment marked with the following symbol:
