condensation is to be expected.(home and office environments fall under this

category)

Pollution degree 3

Conduc

tive 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

he 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 Pol

lution degree class 2 environments.
