Guidance and manufacturer's declaration - electromagnetic immunity
The MiniOX 3000 is intended for use in the electromagnetic environment specified below. The customer or the
®
user of the MiniOX 3000 should assure that it is used in such an environment.

Conducted RF 3 Vrms
IEC 61000-4-6 150 kHz to 80 MHz
Radiated RF 20 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
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 MiniOX 3000 is used exceeds the applicable RF compliance level above, the MiniOX
®
be observed to verify normal operation. If abnormal performance is observed, additional measures may
be necessary, such as reorienting or relocating the MiniOX
Over the frequency range 150 kHz to 80 MHz, induced voltages across the sensor cable should be less
b
than 1.2 Vrms, and, over the frequency range 80 MHz to 2.5 GHz, field strengths should be less than 20
V/m.

Level
Portable and mobile RF communications equipment
should be used no closer to any part of the MiniOX
including cables, than the recommended separation
distance calculated from the equation applicable to the
frequency of the transmitter.
Recommended separation distance
1.2 Vrms d = 2.9 √ P
20 V/m d = 2.9 √ P
d = 2.9 √ P
where P is the maximum output power rating of the trans-
mitter in watts (W) according to the transmitter manufac-
turer and d is the recommended separation distance in
metres (m).
