EMC TABLES
Guidance and manufacturer's declaration-electromagnetic immunity
The TIE-210 Thermometer is intended for use in the electromagnetic environment specified
below. The customer or the user of the TIE-210 Thermometer should assure that it is used in
such an environment.
Immunity IEC 60601
test test level
Radiated 80 MHz
RF IEC to 2,5
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 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) tele-
phones 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 TIE-210 Thermometer is used exceeds
the applicable RF compliance level above, the TIE-210 Thermometer should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the TIE-210 Thermometer.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Compliance Electromagnetic environment-guidance
level
3 V/m Portable and mobile RF communications
equipment should be used no closer to any part of
the TIE-210 Thermometer, including cables, than
the recommended separation distance calculated
from the 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 deter-
mined by an electromagnetic site surveyª, should be
less than the compliance level in
each frequency range
