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
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.
