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
DMM indicates in which environment the device may be used.
Pollution
degree 1
No pollution or only dry, nonconductive pollution occurs. The
pollution has no influence (only to be found in hermetically sealed
enclosures).
Pollution
degree 2
Only nonconductive pollution occurs. Occasionally, temporary
conductivity caused by condensation is to be expected (home and
office environments fall under this category).
Pollution
degree 3
Conductive pollution occurs, or dry nonconductive pollution occurs
that 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
degree 4
The pollution generates persistent conductivity caused by
conductive 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.
