Pollution Degree The InfiniiVision 3000T X-Series oscilloscopes may be operated in environments
of Pollution Degree 2 (or Pollution Degree 1).
Pollution Degree
Definitions
Pollution Degree 1: No pollution or only dry, non-conductive pollution occurs.
The pollution has no influence. Example: A clean room or climate controlled
office environment.
Pollution Degree 2. Normally only dry non-conductive pollution occurs.
Occasionally a temporary conductivity caused by condensation may occur.
Example: General indoor environment.
Pollution Degree 3: Conductive pollution occurs, or dry, non-conductive
pollution occurs which becomes conductive due to condensation which is
expected. Example: Sheltered outdoor environment.
