9. Notes on electromagnetic compatibility
Guidelines and manufacturer's declaration - Electromagnetic immunity
The scale type 6752 is intended for use in the ELECTRICAL ENVIRONMENT specified below. The customer or the user
of the 6752 series scales should ensure that it is used in such an environment.
Immunity test
Conducted RF
disturbances according
to IEC 61000-4-6
Radiated RF
disturbances according
to IEC 61000-4-3
NOTE 1: At 26 MHz and 800 MHz the higher frequency range applies
NOTE 2: These guidelines may not be applicable in all cases. The propagation of electromagnetic quantities is influenced by
absorptions and reflections of buildings, objects and people
a) The field strength of stationary transmitters, such as base stations of radio telephones and land mobile radios, amateur radio station,
AM and FM radio and television transmitters cannot be predicted theoretically with accuracy. To determine the electromagnetic en-
vironment with respect to stationary transmitters, a site study should be considered. If the measured field strength at the site where
the unit is used exceeds the above compliance levels, the unit should be observed to demonstrate intended operation. If unusual per-
formance characteristics are observed, additional measures may be required, such as modification or relocation of the unit.
b) Over the frequency range 150 kHz to 80 MHz, the field strength should be less than 3 V/m.

Electromagnetic environment -
Guidelines
Portable and mobile radios shall not be
used at a distance from the scale 6752,
including lines, less than the
recommended separation distance
calculated using the equation
appropriate to the frequency of
transmission.
Recommended protective distance:
d = 0,4 √P
d = 0,4 √P
for 80 MHz to 800 MHz
d = 0,7 √P
for 800 MHz to 2,7 GHz
with P as the nominal power of the
transmitter in watts (W) according to
the transmitter manufacturer's
specifications and d as the
recommended protective distance in
metres (m).
The field strength of stationary radio
transmitters is lower than the
compliance level at all frequencies
according to an on-site investigation.
Interference is possible in the vicinity of
devices bearing the following
pictogram.
