For each of the supported standards the corresponding cleanliness/contamination classes are shown and cannot be modified. Cleanliness/contamination classes allocate normalized particle numbers into cleanliness/contamination level. For more information on the supported standards, see Introduction to Standards.

1

Size Classes

Displays the cleanliness/contamination level corresponding to normalized particle counts. Only valid for A, V.

2

Class Table Usage

Identical Class Table for all Particle Size Classes: Applies one cleanliness code classification table to all particle size classes;

Individual Class Tables for each Particle Size Class: Applies one individual cleanliness code classification table per particle size class, i.e. each particle size class has its own cleanliness classification table.

3

Operator for Cleanliness Classes

Defines the handling of the class border limits.

4

Cleanliness Code Notation

Options for displaying the cleanliness/contamination classification in the condensed one-line notation with class names or without class names.

Example:
CCC=1/2/3/4 or CCC=A1/B2/C3/D4.

The latter example shows a notation in which the letter represents a certain particle size class and the number stands for the corresponding cleanliness/contamination level, indicating the detected and normalized number of particles which belong to this particle size class.
