You can combine multiple filter conditions together to further define the data appearing in your Alarm Analysis object. As you create each condition, the Alarm Analysis object automatically places the boolean operator AND before the new filter condition and appends the new condition to the existing one.
If you want to change the boolean operator, you can replace it with either the OR operator or the NOT operator by selecting a condition and clicking the OR button or the NOT button.
You can also insert new conditions between existing ones by using the Insert Filter button. When you select this button, the Add dialog box appears, allowing you to create a new filter condition. When you complete the filter and click OK, the new filter appears before the previously selected filter, as the following figure shows:
