Power frequency
(50/60 Hz)
magnetic field
IEC 61000-4-8
Power frequency magnetic
fields should be at levels
characteristic of a typical
location in a typical
commercial or hospital
environment.
NOTE UT is the a.c. mains voltage prior to application of the test level.
Guidance and manufacturer’s declaration – electromagnetic immunity
The model A228/A248/A228I/A248I is intended for use in the electromagnetic environment specified below.
The customer or the user of the model A228/A248/A228I/A248I should assure that it is used in such an
environment.
Electromagnetic environment – guidance
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3
3 Vrms
150 kHz to
80MHz
3 V/m
80 MHz to
2,5 GHz
Portable and mobile RF communications equipment
should be used no closer to any part of the model
A228/A248/A228I/A248I, including cables, than the
recommended separation distance calculated from
the equation applicable to the frequency of the
transmitter.
Recommended separation distance
d = 1,2
d = 1,2 80MHz to 800MHz
d = 2,3 800 MHz to 2,5GHz
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,
a
should be less than the compliance level in each
frequency range.
b
Interference may occur in the
vicinity of equipment marked with the following
