IMMUNITY
The Gas Module 3 is intended for use in the electromagnetic environment specified below. The
customer or the user of the Gas Module 3 should assure that it is used in such an environment.
IMMUNITY IEC 60601 TEST
TEST LEVEL
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: At 80 MHz and 800 MHz, the higher frequency range
applies.
NOTE: 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 the-
oretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an elec-
tromagnetic site survey should be considered. If the measured field strength in the location in which the
Gas Module 3 is used exceeds the applicable RF compliance level above, the Gas Module 3 should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the Gas Module 3.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

COMPLIANCE ELECTROMAGNETIC
LEVEL ENVIRONMENT - GUIDANCE
Portable and mobile RF
communications equipment should be
used no closer to any part of the Gas
Module 3, including cables, than the
recommended separation distance
calculated from the equation
applicable to the frequency of the
transmitter.
Recommended separation
distance
3 Vrms d = 1.2 x P
3 V/m d = 1.2 x P
d = 2.3 x
P
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 determined by an
electromagnetic site survey,
less than the compliance level in each
frequency range.
Interference may occur in the
vicinity of equipment marked
with the following symbol:
