EMC Guidance and Manufacturer’s Declaration
Guidance and manufacturer’s declaration - electromagnetic emissions.
The M-545 is intended for use in the electromagnetic environment specified below. The
customer or user of this scale should assure that it is used in such an environment.
Emission Test Compliance Electromagnetic environment-
guidance
RF emissions
CISPR 11 Group 1 This scale uses RF energy only for
its internal function. Therefore, its
RF emissions are very low and not
likely to cause any interference in
nearby electronic equipment.
RF emissions
CISPR 11 Class B This scale is suitable for use in all
establishments, including domestic
establishments and those directly
connected to the public low-
voltage power supply network that
supplies buildings used for
domestic purposes.
Harmonic emissions
IEC 61000-3-2 Class A
Voltage fluctuations/flicker
