CAT IV and up to 1000V in CAT III.
5. Pollution degree
IEC 61010-1 specifies different types of pollution environments, for which different
protective measures are necessary to ensure safety. Harsher environments require
more protection, and the protection against the pollution which is to be found in a
certain environment depends mainly on the insulation and the enclosure properties.
The pollution degree rating of the DVM indicates in which environment the device
may be used.
Pollution
No pollution or only dry, nonconductive pollution occurs. The pollution
degree 1
has no influence. (only to be found in hermetically sealed enclosures)
Pollution
Only nonconductive pollution occurs. Occasionally, temporary
degree 2
conductivity caused by condensation is to be expected.(home and office
environments fall under this category)
Pollution
Conductive pollution occurs, or dry nonconductive pollution occurs that
degree 3
becomes conductive due to condensation that is to be expected.
(industrial environments and environments exposed to outside air - but
not in contact with precipitation)
Pollution
The pollution generates persistent conductivity caused by conductive
degree 4
dust or by rain or snow. (exposed outdoor environments and
environments where high humidity levels or high concentrations of fine
particles occur)
Warning:
This device was designed in accordance with EN 61010-1 pollution degree 2. This
implies that certain restrictions in use apply that are related to pollution which can
occur within the environment of use. Refer to the table above.
This device is only suitable for measurements in Pollution degree
class 2 environments.
