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-
ment categories.
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).
