Safety Information
Accuracy
We dene 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.
dgt.
(resolution)
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-signicant digit.

Safety Information
Measurement Categories
To ensure safe operation of measuring instruments, IEC 61010
establishes safety standards for various electrical environments,
categorized as CAT II to CAT IV, and called measurement categories.
DANGER
•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.
This instrument conforms to the safety requirements for CAT III 600 V
measuring instruments.
CAT II: When directly measuring the electrical outlet receptacles of the
primary electrical circuits in equipment connected to an AC electrical
outlet by a power cord (portable tools, household appliances, etc.)
CAT III: When measuring the primary electrical circuits of heavy equipment
(xed installations) connected 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).
