This instrument meets CAT. III 600V. To ensure safe operation of measuring instruments, IEC 61010 establishes
safety standards for various electrical environments, categorized as CAT.I 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.
CAT.I: Secondary electrical circuits connected to an AC electrical outlet through a transformer or similar device.
CAT.II: Primary 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).
