Safety Information

This instrument complies with CAT IV safety requirements.

To ensure safe operation of measurement instruments IEC

61010 establishes safety standards for various electrical envi-

ronments, categorized as CAT II to CAT IV, and called measure-

Using a measurement instrument in an environment designated

with a higher-numbered category than that for which the instru-

ment 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.

Measurement categories

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 distri-

bution 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).
