Define individual particle length and width size classes in the Center Screen Area if required, and select the desired acceptance criteria in the Workbench Area. The number of displayed columns is dependent on the settings in the workbench area.

In the Image Gallery, all particles are displayed by default from 5 µm length and width onwards. As a Supervisor, you can change the minimum size of the displayed particles in the Region Filter tool in the Region Filter workbench. By default, the Region Filter workbench is set to run silent, see Region Filter.

  1. You have defined the basic template settings.
  1. Open step Define Length Classes.
  2. The following view is displayed.
  3. Define the settings in the workbench area. Define the length or width classes. Select the Classification Parameter, if required.

    You have the following options for length classification:
    - Feret Max
    - Length X
    - Fiber Length
    - ECD
    Default value: Feret Max
    Note that the selection of other classification parameter than the default parameter is only recommended for non-standard based analysis.
    You have the following options for width classification:
    - Feret Min
    - Length Y
    - ECD
    - Max. Inscribed Circle
    Default value: Feret Min
    For more information on Length and Width Classification, see Measurement Parameters for Length and Width Classification.
  4. Activate the Selection.

    You have the following options:
    - Activate Particle Height Measurement to show additional columns in the center area to define the particles of certain size classes to be considered for particle height measurement.
    - Activate EDS Measurement with SEM (Correlative Workflow) for a correlative workflow. If activated, additional columns are shown in the Classes table to define the particles for EM/EDS analysis. For correlative LM/EM-EDS workflow, you operate in Free Mode and need to activate the S&F Find List tool, see Correlative Workflows.
  5. Defined particles for EM/EDS measurement will appear in this list.
  6. In the Operator for Size Classification section, define the handling at the class border limits for the particle size classification.
  7. In the Acceptance Criterion section, activate Allowed Number of Particles for the definition of acceptance criteria based on the allowed maximum particle number per size class.

    You have the following options:
    - Absolute Count (absolute particle number)
    - Normalized (N) (= absolute particle number/component number)
    - Normalized (A) (= absolute particle number/wetted component area)*1000 [cm2]
    - Normalized (V) (= absolute particle number/wetted component volume)*100 [cm3]
  8. Select the Operator for Acceptance Criterion to define the handling at the class border limit for the definition of acceptance criteria.
  9. Select the Allowed Number of Particles.

    This function is only active, if in the Acceptance Criterion section Allowed Number of Particles is activated. Here, you define the allowed number of particles per type class and for "class all with or without fibers", see Type Classification for Class "All" Tool. You have the following options:
    - Same Limit Value for all Types. Define one limit value for allowed particle numbers independent of the particle type. This limit value is also valid for "class all/with or without fiber". The defined values are the base for the approval rating displayed in the Size Distribution View.
    - Individual Limit Value per Type. Define individual limit values for allowed particle numbers for each particle type. The limit value for allowed particle numbers in "class all/with or without fiber" is equal to the sum of the allowed particle numbers of the particle types. The defined values are the base for approval ratings displayed in the Size Distribution View.
  10. Continue in the Classes table, see Defining Length and Width Classes (Center Screen Area)
