Guidance and Manufacturer's Declaration – Electromagnetic Immunity
The AutoVector Fluid Immersion Simulator is intended for use in the electromagnetic environment specified below.
®
The customer or the user of the Auto Vector Fluid Immersion Simulator should assure that it is used in such an
environment.
Immunity test IEC 60601 test level Compliance level Electromagnetic environment – guidance
Conducted RF 3 Vrms
IEC 61000-4-6 150 kHz to 80 MHz
Radiated RF 3 V/m
IEC 61000-4-3 80 MHz to 2,5 GHz
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 land
a
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 Auto Vector Fluid Immersion
Simulator is used exceeds the applicable RF compliance level above, the Auto Vector Fluid Immersion Simulator
should be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the Auto Vector Fluid Immersion Simulator.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

3 Vrms Portable and mobile RF communications equipment
should be used no closer to any part of the Auto Vector
Fluid Immersion Simulator, including cables, than the
recommended separation distance calculated from the
3 V/m equation applicable to the frequency of the transmitter.
Recommended separation distance
d=1.2√P
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 metres (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
be less than the compliance level in each frequency
range.
