Guidance and manufacturer´s declaration – electromagnetic immunity
The Infrared Thermometer is intended for use in the electromagnetic environment specified below. The customer
or the user of the Infrared Thermometer should assure that it is used in such an environment.
Immunity test
IEC 60601
test level
3 V/m 80
Radiated RF
MHz to 2.5
IEC 61000-4-3
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 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 Infrared Thermometer is used ex-
ceeds the applicable RF compliance level above, the Infrared Thermometer should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as re -orienting or
relocating the Infrared Thermometer.
Compli-
Electromagnetic environment - guidance
ance level
Portable and mobile RF communications equipment should be used
no closer to any part of the Infrared Thermometer, including cables,
than the recommended separation distance calculated from the
equation applicable to the frequency of the transmitter. Recommend-
ed separation distance
10V/m
\Where p is the maximum output power rating of the transmitter in
watts (W) according to the transmitter manufacturer and d is recom-
mended separation distance in meters (m).b Field strengths from
fixed RF transmitters, as determined by an Electromagnetic site sur-
vey, a should be less than the compliance level in each frequency
range. Interference may occur in the vicinity of equipment marked
with the following symbol:
80 MHz to 800 MHZ
800 MHz to 2,5 GHz
