Safety Information

We define measurement tolerances in terms of rdg. (reading)

and dgt. (digit) values, with the following meanings:

rdg. (reading or displayed value)

The value currently being measured and indicated on the

measuring instrument.

rdg. (reading or displayed value)

The smallest displayable unit on a digital measuring instrument,

i.e., the input value that causes the digital display to show a “1”

as the least-significant digit.

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.

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.

Accuracy

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 distribution 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).
