●
The following effects can cause burns and fire or damage to the measurement
site:
– Eddy current loss can cause heating of the sensor head.
– Dielectric heating can cause heating of cord insulation and other materials.
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 setup only in electrical environments for which
they are rated.
●
0 - Instruments without rated measurement category
For measurements performed on circuits not directly connected to mains, for
example, 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.
