### Step 3: Stage Calibration Setup - Standard tab

The Standards tab contains settings which allow you to associate standard certification with a file and axis.

Vision Stage Calibration Setup dialog box - Standard tab

Axis: Specifies the axis to which the certification data applies.

Open: Used to open or import an existing standard certification file to be used for the selected axis.

Edit: Used to bring up the Standard Properties dialog box to edit the standard certification file data.

Save: Used to save the standard certification data to a file. Note that this can be used to save data that was entered in the Standard column during the calibration or verification runs. For example, if you processed the X axis and entered the X axis data, you could save the data to file, select the Y axis, and open the file to use the standard data from the X axis for the Y axis calibration.

The Standard Properties dialog box is launched from the Edit button.

Standard Properties dialog box

Description: A short description of the calibration standard, such as 100 millimeter linear. This will be used in generating the calibration certification document.

Serial Number: The standard serial number is used in generating the calibration certification document.

Units: Used for setting the units of the calibration standard.

Temperature

Compensation: To compensate the expansion of the Standard due to temperature difference between temperature when Vision Stage Calibration is performed and the temperature when the Standard is certified. Compensation will be applied when this option is selected.

Coefficient: Linear coefficient of thermal expansion of the Standard. Type the value that is found in the Standard Certification document.

Cert Temp(C): The reference temperature of Standard certificate data. Type the value that is found in the Standard Certification document.

Date: Specifies the certification data of the standard. This will be used in generating the calibration certification document.

Data: Certification values for the standard. This standard can then be associated with an axis to allow automatic data entry and reuse. For a single axis standard, such as a linear ruler or gage blocks, the first value would normally be zero, as that would be the starting point on a hard gaging certification. The data pattern for the XY grid is that of a perimeter rectangle. The XY data points are entered in ascending order for each side of the rectangle in the order of –Y line, +Y line, -X line, +X line. Note that the data for the rectangle corner points would be entered twice, as they lie on 2 data lines.

Note: Editing the Data list follows standard Windows list box editing. If you don’t see an edit box in the list, click at the bottom of the list. An edit box will appear as shown in the Standard Properties dialog box image.

Insert: Used to insert a blank row before current highlighted row in the Data list.

Delete: Used to delete current highlighted row in the Data list.
