Safety Notes
Measurement categories
To ensure safe operation of measuring instruments, IEC 61010
specifies the measurement categories, which classifies testing and
measuring circuits into three categories according to the types of
mains circuits to which they are intended to be connected.
DANGER
• Do not use a measuring instrument for
measurements on a mains circuit that exceeds the
range of the measurement category rated for the
instrument. Failure to observe this can cause a
severe accident.
• Do not use a measuring instrument without a
measurement category rating for measurements on
a mains circuit. Failure to observe this can cause a
severe accident.
This instrument conforms to the safety requirements for CAT II 300 V,
CAT III 150 V, CAT IV 100 V measuring instruments.
Measurement category II (CAT II)
Applicable to test and measuring circuits connected directly to
utilization points (socket outlets and similar points) of the low-
voltage mains installation.
Example: Measurements on household appliances, portable tools,
and similar equipment, and on the consumer side only
of socket-outlets in the fixed installation.
