Measurement categories
• Using a measuring instrument in an environment designated with a higher-
numbered category than that for which the instrument is rated could result in a
severe accident, and must be carefully avoided.
• Never use a measuring instrument that lacks category labeling in a CAT II to
CAT IV measurement environment. Doing so could result in a serious accident.
CAT II: When directly measuring the electrical outlet receptacles of the primary electrical circuits in
equipment connected to an AC electrical outlet with a power cord (portable tools, house-
hold appliances, etc.).
CAT III: When measuring the primary electrical circuits of heavy equipment (fixed installations) con-
nected directly to the distribution panel, and feeders from the distribution panel to outlets.
CAT IV: When measuring the circuit from the service drop to the service entrance, and to the power
meter and primary overcurrent protection device (distribution panel).
