Guidance and manufacturer’s declaration — electromagnetic immunity
The MA 33 is intended for use in the electromagnetic environment specified below. The customer or the user of the MA 33 should assure
that it is used in such an environment,
Immunity test
IEC / EN 60601 test level
Compliance
level
Electromagnetic environment – guidance
Portable and mobile RF communications equipment
should be used no closer to any parts of the MA 33,
including cables, than the recommended separation
distance calculated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance:
Conducted RF
3 Vrms
3 Vrms
Pd 2,1=
IEC / EN 61000-4-6
150kHz to 80 MHz
6 Vrms in ISM bands
150kHz to 80 MHz
80 % AM at 1 kHz
6 Vrms
Radiated RF
3 V/m
3 V/m
Pd 2,1=
80 MHz to 800 MHz
IEC / EN 61000-4-3
80 MHz to 2,7 GHz
80 % AM at 1 kKz
Pd 3,2=
800 MHz to 2,7 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 deter-
mined 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 symbol:
NOTE1 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 reflection from
structures, objects and people.
a)
Field strengths from fixed 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 fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the
location in which the Instrument is used exceeds the applicable RF compliance level above, the Instrument should be observed to verify
normal operation, If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the
Instrument.
b)
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
