Measurement categories
IEC 61010-2-030 defines measurement categories that rate instruments on their ability
to resist short transient overvoltages that occur in addition to the working voltage. Use
the measurement instrument and accessories only in electrical environments for which
they are rated.
●
O - Instruments without rated measurement category
For measurements performed on circuits not directly connected to mains, for exam-
ple, electronics, circuits powered by batteries, and specially protected secondary
circuits. This measurement category is also known as CAT I.
●
CAT II:
For measurements performed on circuits directly connected to the low-voltage
installation by a standard socket outlet, for example, household appliances and
portable tools.
●
CAT III:
For measurements performed in the building installation, such as junction boxes,
circuit breakers, distribution boards, and equipment with permanent connection to
the fixed installation.
●
CAT IV:
For measurements performed at the source of the low-voltage installation, such as
electricity meters and primary overcurrent protection devices.
