Pollution Only nonconductive pollution occurs. Occasionally,
degree 2 temporary conductivity caused by condensation is to be
expected. (home and office environments fall under this
category)
Pollution Conductive pollution occurs, or dry nonconductive pollution
degree 3 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 The pollution generates persistent conductivity caused by
degree 4 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.
