Calibration Manager

Use the Calibration Manager dialog box to manage the sizes, values, and precision of all items that can be calibrated. Open this tool by selecting a lookup table, then selecting Tools > Calibration Manager or by clicking the Calibration Manager button on the toolbar.

You can either set up your lookup tables manually or from a calibration file. You can also copy lookup table data from other sources.

You can enter the required inputs, number of rows and columns and an initial value for lookup table cells when you add a lookup table. Use the File > New menu items to make new lookup tables.

Set Up Lookup Tables from a Calibration File

Setting up lookup tables with a calibration file involves two steps.

StepDescription

Import calibration files into the Calibration Manager

You can import calibration files from the CAGE Browser by selecting File > Import > Calibration . Your selected file opens in the Calibration Manager.

You can also open the Calibration Manager and import calibration files from within the Calibration Manager window by using the following procedure:

  1. In the Calibration Manager, open the file by clicking the Open Calibration File button in the toolbar.

    The Import Calibration Data dialog box opens.

  2. Browse to the calibration file, select it, and click Open.

In the Calibration Manager, review the files you have imported:

  • Your imported calibration file items appear in the Calibration File Contents pane at the top right.

  • The lookup tables, normalizers, and other items in your project appear on the left in the Project Calibration Items pane.

  • The values of the selected item appear in the lower pane, so you can inspect the values in your calibration file and current project lookup tables. Because the import process filters out empty data, any empty variables do not appear.

Import calibration file values into a Lookup Table

To import the data in your calibration file into a lookup table in your project:

  1. Click to select both the lookup table in the Calibration File Contents pane and the lookup table in the Project Calibration Items pane with which you want to associate it.

  2. Associate these two items by clicking the button . The values in the calibration file load into the lookup table. You can inspect the values in the lower pane by clicking to select the lookup table in the Project Calibration Items pane.

    To associate all the items listed in the Project Calibration Items pane with items that have the same names listed in the Calibration File Contents pane, click the Auto button .

    To find particular names in a large calibration file, you can click the Calibration File Contents list and type the first few letters of the item that you want to find. The cursor moves to the letters specified as you type.

  3. Check the display of your lookup table, and then click Close.

When you close the Calibration Manager, you can view your updated lookup tables in CAGE. If you want to compare or revert to an earlier version of your lookup table, select View > History.

Set Up Lookup Tables Manually

To set up the lookup tables manually:

  1. Select the normalizer or lookup table to set up from the list on the left.

  2. Enter the number of rows and columns in the edit boxes on the left and select initial values for each cell in the lookup table.

  3. Click Apply.

    When initializing lookup tables for a feature calibration, consider your strategy. CAGE cannot fill those lookup tables if you try to divide by zero. Initialize the modifier lookup tables with a value of 1 for all cells if they are multipliers, and a value of 0 if they are added to other lookup tables.

  4. Check the display of your lookup table, then click Close.

Copy Lookup Table Data from Other Sources

You can paste lookup table values from other applications by copying the array in the other application and clicking Paste  in the Calibration Manager:

  1. Open the desired file and copy the array that you want to import.

  2. In the Calibration Manager dialog box, click Paste .

You can also set up a lookup table from a text file:

  1. Click Set Up From ASCII File in the toolbar.

  2. Select the desired file, then click Open.

    If the size of the lookup table is different from the file that you are copying, CAGE changes the size of the lookup table in the session.
