#### Defining Pitch/Runout Data

The Pitch/Runout tab is used to define all values necessary for the description of pitch/runout measurement.

Measurement Area

There are 2 options for the definition of the pitch point which establishes the probing points for the measurement:

- Pitch point definition: Select the Definition that you want to define.

- A: Selection of a master grid point by entering the line and column number. This is the default option with"reference point on master grid " is offered as pitch point. All probing points and machine paths are generated automatically by the program.

- B: Numeric input of radius and z coordinate of the pitch point.

Evaluation Area

Define evaluation parameters now: If you want to define evaluation parameters, select this value and the evaluation options will be available for editing.

- Plot Magnification: This value is used to define magnification scale for the created report in plot server. If you specify ‘0’, the evaluation is carried out, but no plot output will be created; however, the evaluation parameters are stored in the measurement result.

- Calculate Tols: Click this button to calculate the Tolerances. If the gear quality was specified in the Geometry Parameters dialog box, the tolerances Fp, fp and fu are computed and automatically added to the Tolerance values according to the standard you selected. If no gear quality was specified, the tolerances will not be calculated.

Tolerances (mm/inch)

This section allows you to define the following tolerances for evaluating pitch and runout.

- Cumulative pitch deviation (Fp)

- Individual pitch deviation (fp)

- Adjacent pitch deviation (fu)

- Individual pitch deviation (Rp)

- Radial runout (Fr)

Note: With the measured pitch points, a runout evaluation can also be executed.
