○Measurement categories (Over-voltage categories)
　 To ensure safe operation of measuring instruments, IEC establishes safety 61010
standards for various electrical environments, categorized as O to CAT IV, and called
measurement categories. These are defined as indicated below.
　 Higher-numbered categories correspond to electrical environments with greater
momentary energy, so a measuring instrument designed for CAT environments Ⅲ
can endure greater momentary energy than one designed for CAT Ⅱ.
　 ⅡCAT ： Primary electrical circuits of equipment connected to an AC electrical
outlet by a power cord.
　 ⅢCAT ： Primary electrical circuits of the equipment connected directly to the
distribution panel, and feeders from the distribution panel to outlets.
Designed to meet CAT V when the cap and protective cover is attached to the Ⅲ600
test lead and to meet CAT V when the cap and protective cover is not attached Ⅱ 600
to the test lead.
