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
