Symbols for various standards

Measurement categories

This instrument complies with CAT III safety

requirements.

To ensure safe operation of measurement

instruments, IEC 61010 establishes safety standards

for various electrical environments, categorized as

CAT II to CAT IV, and called measurement

categories. These are defined as follows.

CAT II: Primary electrical circuits in equipment

connected to an AC electrical outlet by a

power cord (portable tools, household

appliances, etc.)

CAT II covers directly measuring

electrical outlet receptacles.

CAT III: Primary electrical circuits of heavy

equipment (fixed installations) connected

directly to the distribution panel, and

feeders from the distribution panel to

outlets.

CAT IV: he circuit from the service drop to the

service entrance, and to the power meter

and primary overcurrent protection device

(distribution panel).

―――――――――――――――――――――――――――

Safety

――――――――――――――――――――――――

Using a measurement 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.

Use of a measurement instrument that is not CAT-

rated in CAT II to CAT IV measurement

applications could result in a severe accident, and

must be carefully avoided.
