To ensure safe operation of measuring instruments, IEC 61010 establishes safety standards
for various electrical environments, 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 power supply.

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 entrance, and to the power
meter and primary overcurrent protection device (distribution panel).

Interior wiring
Incoming wire

O: Device which is
not directly
connected to themain power supply

SocketPlease read the "Safety Warnings" in the instruction manual supplied with the instrument thoroughly and completelycorrect use. Failure to follow the safety rules can cause fire, trouble, electrical shock, etc. Therefore, make sure
Safety Warnings : forto operate the instrument on a correct power supply and voltage rating marked on each instrument.
