Creating a Multiple Numeric Limit Test in TestStand

Use the Tests step type to perform limit checks the measured data. Complete the following steps to add a multiple numeric limit test to your sequence.

  1. Open or create a PCB Assembly Test sequence in TestStand.
  2. In the list of steps, expand the Tests folder.

  3. Add the Multiple Numeric Limit Test step to your sequence.
  4. Click the Module tab in the step settings.
  5. Select the VI path. The VI loads.
  6. Reference the data types returned by the VI to create the TestStand variables that represent your measurement data.
    • For simple data types (for example, number, string, boolean or array), create named TestStand variables with the corresponding type.
    • For container data types, click the Create/Update Custom Data Type button to create a custom data type. You can then create a TestStand variable using this custom data type.

  7. Assign each VI return value to the corresponding TestStand variable.
  8. Click the Limits tab in the step settings. Use this tab to define limits.

    1. Specify a Measurement Name for each limit.
    2. Select the desired Comparison Type.
    3. Update the Low and High limits.
    Add additional limits as necessary.
  9. Click the Data Source tab in the step settings. Set the desired TestStand variable as the Data Source to evaluate for each limit check.
  10. Return to the Module tab and declare any other required output variables.
Tip Examine the Functional Demo Sequences for examples that use the Multiple Numeric Limits test step.
