11. Notes on electromagnetic compatibility
Guidelines and manufacturer's declaration - Electromagnetic immunity
The scales of type series 6730 and 6731 are intended for operation in the ELECTRICAL ENVIRONMENT specified be-
low. The customer or the user of the scales types 6730 and 6731 should ensure that it is used in such an environment.
Immunity test
Discharge of static elec-
tricity (ESD) according
to IEC 61000-4-2
Fast transient electrical
disturbance
magnitudes/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 supply
frequency (50/60 Hz)
according to IEC

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 be that of a typical business or
hospital environment.
The quality of the supply voltage
should be 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 6730 and 6731
scales requires continued FUNCTION
even when power interruptions occur,
it is recommended that the 6730 and
6731 scales be powered from an
uninterruptible power supply.
Magnetic fields at the mains
frequency should correspond to
typical values found in business and
hospital environments.
