Immunity test: Power frequency (50/60 Hz); magnetic field; IEC 61000-4-8
IEC 60601 test level: 30 A/m
Compliance level: 30 A/m
Electromagnetic environment – guidance: Power frequency magnetic fields should be at levels
characteristic of a typical location in a typical domestic, commercial, or hospital environment.
Immunity test: Radiated RF; IEC 61000-4-3
IEC 60601 test level: 10 V/m; 80 MHz to 2.7 GHz
Compliance level: 10 V/m
Electromagnetic environment – guidance:
Recommended separation distance
d = 1.2 √P
80 MHz to 800 MHz
d = 2.3 √P
800 MHz to 2.5 GHz
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 metres (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 symbol:
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 reflection from structures, objects and people.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and
a
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 Sensor is used exceeds the applicable RF compliance level above, the Sensor should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary,
such as re-orienting or relocating the Sensor.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
Recommended separation distances between portable and mobile RF
communications equipment and the Sensor
The Sensor is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the Sensor can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the Sensor as recommended below, according to the maximum output power of the
communications equipment.
