### Step2: Setting NC Gage Parameters

Touch the Setup soft key from the main screen. The Setup screen appears.

This screen lets you define several measurement and hardware parameters used during measurement.

To modify the general NC Gage parameters:

1. Modify values as needed.

2. Touch Apply to save the changes that have been made, or touch Return to exit this screen without saving.

This screen contains these items:

Available Navigation Bar Soft Keys on this Screen:

| Backward When enabled, this soft key scrolls back to any additional buttons available on the first page for this screen. |  | Define Tolerance Chart This soft key allows the user to enter the tolerance class definition screen. See the "User Tolerance Chart" topic.
| Setup Work Orientation for the Machine This soft key lets you define what work face you will use in your part program. See the "Work Face Setup" topic. |  | Apply or Confirm Changes This soft key accepts changes made to any fields, settings, or selections on the current screen. In some cases, this soft key adds a command to the NC Gage part program.
| Help This soft key accesses the NC Gage help file. |  |
| Return This soft key returns the view up one level to the previous screen. |  | Forward When enabled, this soft key scrolls forward to any additional soft keys available on the second page for this screen.

Tolerance Area:

- Plus – Specifies the default plus tolerance value by which your part dimensions will be evaluated.

- Minus – Specifies the default minus tolerance value by which your part dimensions will be evaluated.

- Setting these values lets you specify tolerances for future recall in the Tolerance screen of any feature by using the Select Global Tolerance Limit list located in that screen. This provides you with a rapid way of selecting and entering the same tolerance values repeatedly. See the "User Tolerance Chart" topic.

Snap Settings Area:

- Dimension Snap Value - This causes NC Gage to round the nominal results that are found for any feature by the probe during the learn process. The results are round using two criteria. First, the results are rounded to the number of decimal values in this field. Second, the results are rounded to the nearest magnitude in this field. As an example, if the result is 0.068 and the value in this box is 0.03, then the process would be as follows. First, the 0.068 would be rounded to the decimal value of two (two decimal spots) which would result in 0.07. Second, the value would be rounded to the nearest magnitude of "3" which would modify 0.07 to 0.06 since "6" is a multiple of "3."

- Angle Snap Value - This works in the same principal as the Dimension Snap Value but for angle measurement.

Counter Display:

Machine:

- No Tool Length – No tool length is added to the "machine" position readout.

- Tool Length – The tool length, as stored in the control, is used to display the machine's position in the digital readout display. This adds the tool length to the bottom of the probe to that readout display.

- Probe Tip Center – The probe tip center is shown in the "machine" readout.

Work Offset:

- Tool Length - The tool length, as stored in the control, is used to display the "work offset" position in the digital readout display. This adds the tool length to the bottom of the probe to that readout display.

- No Tool Length – No tool length is added to the "work offset" position readout.

- Probe Tip Center - The probe tip center is shown in the "work offset" readout.

Rates Area:

- Traverse (Feed Rate) - Determines the speed at which the probe travels between program blocks. The units will be millimeters/minute or inches/minute based on the unit selection.

- Finding (Feed Rate) - Determines the speed at which the probe travels when discovering features in learn mode. The units will be millimeters/minute or inches/minute based on the unit selection.

- Prehit (Probing Distance) - Specifies the distance from the theoretical hit location to which the probe will move before taking a hit. This is used during part measurement. The units will be millimeters or inches based on the unit selection.

- Search (Probing Distance) - Provides the distance that the probe will search for the surface. If the probe does not come in contact with the surface before reaching this distance the measurement will fail. The units will be millimeters or inches based on the unit selection.

Report Save Option:

- File - Specifies the location of where the report will be saved. The program will also be saved to the same path in the subdirectory PRG.

- Overwrite - If selected, specifies that each new report file will overwrite the last.

- Auto - If selected, specifies that each time a report is saved, NC Gage will automatically increment the file name so that no previous data is overwritten and lost.

- Index - This resets the index value for incremental saving of the report. If Auto is selected the report file name will be saved using this index number. It will then be incremented by 1 with each subsequent save.
