Guidance and manufacturer's declaration—electromagnetic immunity
The Model 773X is intended for use in the electromagnetic environment specified below. The customer or the user
of the Model 773X should assure that it is used in such an electromagnetic environment.
Immunity test
IEC 61000-
Conducted RF
4-6
Radiated RF IEC 61000-4-3
NOTE 1—At 26 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) 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 Model 773X is used exceeds the
applicable RF compliance level above, the Model 773X should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or relocating the scale.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

transmitter manufacturer and d is the
recommended separation distance in meters

Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
should be less than the compliance level in
each frequency range.
