Guidance and manufacturer’s declaration – electromagnetic immunity
BM 60 is intended for use in the electromagnetic environment specified below. The customer or the user of BM 60 should assure that it is used
in such an environment.
Immunity test

Electrostatic discharge (ESD)
IEC 61000-4-2
± 6 kV contact
± 8 kV air
± 6 kV contact

Floors should be wood, concrete or ceramic tile. If
floors are covered with synthetic material, the rela-
tive humidity should be at least 30 %.

Mains power quality should be that of a typical
commercial or hospital environment. If the user of
BM 60 requires continued operation during power
mains interruptions, it is recommended that BM 60
is be powered from an uninterruptible power supply
or a battery.
Power frequency (50/60 Hz)
magnetic field IEC 61000-4-8 3 A/m
3 A/m
Power frequency magnetic fields should be at levels
characteristic of a typical location in a typical com-
mercial or hospital environment.
NOTE: U
T
is the a.c. mains voltage prior to application of the test level.
