Guidance And Manufacturer's Declaration - Electromagnetic Immunity - Eizo FlexScan T1781 Benutzerhandbuch

Guidance and manufacturer's declaration - electromagnetic immunity

The FlexScan T1781 is intended for use in the electromagnetic environment specifi ed below. The customer or the user
of the FlexScan T1781 should assure that it is used in such an environment.
Immunity test IEC/EN60601 test
level
Conducted RF 3Vrms
IEC/EN61000-4-6 150kHz to 80MHz
Radiated RF 3V/m
IEC/EN61000-4-3 80MHz to 2.5GHz
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
refl ection from structures, objects and people.
a
Field strengths from fi xed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile
radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy.
To assess the electromagnetic environment due to fi xed RF transmitters, an electromagnetic site survey should be
considered. If the measured fi eld strength in the location in which the FlexScan T1781 is used exceeds the applicable
RF compliance level above, the FlexScan T1781 should be observed to verify normal operation. If abnormal performance
is observed, additional measures may be necessary, such as reorienting or relocating the FlexScan T1781.
b
Over the frequency range 150 kHz to 80 MHz, fi eld strengths should be less than 3 V/m.
Compliance level Electromagnetic environment - guidance
3Vrms Portable and mobile RF communications
equipment should be used no closer to any part
of the FlexScan T1781, including cables, than
the recommended separation distance calculated
3V/m
from the equation applicable to the frequency of
the transmitter.
Recommended Separation distance
d = 1.2 √ P
d = 1.2 √ P, 80MHz to 800MHz
d = 2.3 √ P, 800MHz 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 fi xed RF transmitters, as
determined by an electromagnetic site survey
should be less than the compliance level in each
frequency range
Interference may occur in the vicinity of equipment
marked with the following symbol.
