Creating Trigger Conditions

You can also define any trigger condition both as a start condition and as a stop condition.

To create a new trigger condition

  1. Select the menu function Open Recorder Configuration in the Measurement menu or press the key combination Ctrl+q.
    The Recorder Configuration dialog box opens.
  2. Go to the Triggers tab.
  3. Click on the pushbutton next to the Start Trigger field.
    The Trigger Editor opens.
  4. Create an empty trigger condition. You have the following options:

    • Toolbar Symbol
    • Context menu: Create new trigger
    • Hotkey: Ctrl+n
  5. Enter a name (default name: TriggerSignaln) and a short description (optional) for the new trigger condition.
  6. Insert one or more variables via the variable selection dialog box. To open the Variable Selection dialog box, you have the following options:

    • Toolbar Symbol
    • Context menu: Insert variables
    • Hotkey: Ins 
  7. In the variable selection dialog box, select one or more variables. The selected variables are marked with the symbol in the variables list.
  8. Click OK.

    The selected variables are displayed in the Formula field.

    Note

    At this point you cannot allocate a raster to the selected variables. The default raster is used. To make modifications to the raster, call up the variable selection dialog box from the experimentation environment and modify the raster there.

  9. Create the formula for the trigger conditions by linking comparative operators from the window area Toolbox with the inserted variables. To add a marked comparative operator to the formula, have the following options:

    • Keyboard operation: Enter
    • Mouse operation: Double-click

    If you have included more than one variable into the formula, you can use the following default links by clicking on the symbol or by pressing the key combination Shift+Alt+F10:

    • Apply AND formatting to these parameters: All inserted variables are interlinked by AND.
    • Apply OR formatting to these parameters: All inserted variables are interlinked by OR.
    • Apply advanced formatting to these parameters: The dialog box AdvancedAutoFomatForm is opened.

    The formula is continuously checked for correct syntax by means of a parser. The parser messages are displayed in the Formula Status box.

    As an advanced user, you can, as an alternative, create the formula directly in the Formula box Closedusing keyboard commands only.

    1. Key in the initial letters of the required variables. When the auto complete function is activated, the provided variables are displayed (see also dialog box Preference Trigger Editor Window).
    2. Using the arrow keys select the corresponding variables.
    3. Accept the variables directly into the Formula box with Enter.

      or

    4. Enter one of the following operators directly:

      • +
      • -
      • *
  10. Click Accept. The trigger condition is displayed in the Defined Trigger Conditions list.

Note

Semantic correctness is not checked! It is, therefore, possible for a measurement to be started incorrectly even though the trigger condition is syntactically correct.

However, syntactically errors will be displayed with a warning sign .
