(Pollution Degree) EN 61010-1:2010(Third Edition)specifies 
pollution degrees and their requirements as follows. The function 
generator falls under degree 2. 
Pollution refers to “addition of foreign matter, solid, liquid, or 
gaseous (ionized gases), that may produce a reduction of dielectric 
strength or surface resistivity”. 
  Pollution degree 1: No pollution or only dry, non-conductive 
pollution occurs. The pollution has no influence. 
  Pollution degree 2: Normally only non-conductive pollution 
occurs. Occasionally, however, a temporary conductivity caused 
by condensation must be expected. 
  Pollution degree 3: Conductive pollution occurs, or dry, non-
conductive pollution occurs which becomes conductive due to 
condensation which is expected. In such conditions, equipment 
is normally protected against exposure to direct sunlight, 
precipitation, and full wind pressure, but neither temperature 
nor humidity is controlled. 
Do not dispose this instrument as unsorted 
municipal waste. Please use a separate collection 
facility or contact the supplier from which this
