This instrument satisfies the marking requirement defined
in the WEEE Directive. This symbol indicates separate
collection for electrical and electronic equipment.
To ensure safe operation of measuring instruments, IEC 61010
establishes safety standards for various electrical environ-
ments, categorized as O to CAT IV, and called measurement
categories. Higher-numbered categories correspond to electrical
environments with greater momentary energy, so a measuring
instrument designed for CAT III environments can endure greater
momentary energy than one designed for CAT II.
O : Circuits which are not directly connected to the mains
CAT II : Electrical circuits of equipment connected to an AC
electrical outlet by a power cord.
CAT III : Primary electrical circuits of the equipment connected
directly to the distribution panel, and feeders from the
distribution panel to outlets.
CAT IV : The circuit from the service drop to the service
entra n c e , and to th e p o wer m e t e r a nd p r i m a r y
