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
Static electricity
discharge (ESD) accor-
ding to IEC 61000-4-2
Fast transient electrical
disturbances magnitu-
des/bursts according to
IEC 61000-4-4
Surges according to IEC
61000-4-5
Voltage dips, short-time
interruptions and
fluctuations of the
supply voltage
according to IEC
61000-4-11
Magnetic field at the
supply frequency (50/60
Hz) according to IEC
61000-4-8
NOTE: UT is the AC mains voltage before the test level is applied.

Guidelines
Floors should be made of wood or
concrete or have ceramic tiles. If the
floor is covered with synthetic
material, the relative humidity must
be at least 30 %.
The quality of the supply voltage
should correspond to that of a typical
business or hospital environment.
The quality of the supply voltage
should correspond to that of a typical
business or hospital environment.
The quality of the supply voltage
should be that of a typical commercial
or hospital environment.
If the user of the 6752 scale requires
continued FUNCTION even when
power interruptions occur, it is
recommended that the scale 6752 be
powered from an uninterruptible
power supply.
Magnetic fields at the mains
frequency should correspond to
typical values found in business and
hospital environments.
