The Add button adds a column to the Test Results area. Click this button to open a dropdown menu where you can select a channel to display in the test results window.

When you select a column header in the Test Results area, the channel name will be displayed in the Channel box (the top box in the Data Column section). Some columns will have required channels and cannot be changed, but if you can change the channel, the Channel box will become a drop-down list with the available channels.    

When you select a column header in the Test Results area, and it is a changeable channel, the Condition dropdown menu becomes available. The conditions will depend on the test and selected channel.

Examples are:

• Avg

This information will be included in the test report to make it easier to see under what conditions the test was conducted.

To save time, you can import and export the session information for use in other sessions (the entire range of data is exported, not just the visible screen).

Once the session information has been completed, you can export the data to a .vbses file. This file will contain all the session information that can then be imported into the open session information field.

The Test Results area has the following default columns:

The software will automatically add columns based on any specified pass criteria.

You can add columns to the Test Results area by clicking the Add button on the Test Setup ribbon or right-clicking anywhere in the Test Results area and selecting the Add option. This will display a drop-down list of all the available channels to display in a results column. By default, this value is displayed as an At End value, which will display the value of the parameter at the end of the run.

You can remove a column by clicking the X that appears when you hover over the column title. If you have removed a column, you can add it again by clicking the Add button and selecting the desired channel.

By default, a column is added without a condition. You can change this by clicking on the column header for the channel you wish to add a condition for. The selected column will be highlighted in yellow. Click on the condition dropdown in the Data column area on the Test Setup tab and select the required condition.
 

You can choose the following conditions for the main results:

• Avg
  The mean average of the parameter during the run.
• Max
  The maximum value of the parameter during the run.
• Min
  The minimum value of the parameter during the run.
• Delta
  The difference between the start and end value of the parameter.
• At Line
  The value of the parameter at the crossing of the specified gate line (e.g. Start/Finish).

You can change the displayed parameter, by selecting a parameter from the dropdown menu above.

You can sort the results in ascending or descending order. To do this, you must click on the relevant column to select it and then click on the Sort Ascending or Sort Descending button on the Test Setup ribbon or right-click in the Test Results area and select the option you need.

You can filter the results by right-clicking on a value in the cell results table (e.g. Time (s)). You can then select to include only results with a value equal to the selected value or with a value that is <= than or >= than the selected value for that channel. You can filter multiple channels. A notification bar above the results will shows the applied filters. You can remove the filters by clicking on the X in the notification bar.

You can copy individual results cells so that they can be pasted into other software applications. Click on the relevant cell to select it, right-click on it and select Copy or use the keyboard shortcut. Select multiple cells by clicking and dragging with the mouse or pressing the Ctrl key when selecting cells. Select all cells between 2 cells by holding down the Shift key and between clicking on the first and the second cell.

You can also copy an individual row, column or the entire results table by selecting the required data area, right-clicking and selecting Copy Row, Copy column or Copy All.

You can rename a column by double-clicking on the column title or by selecting the relevant column and right-clicking and selecting Rename Column or pressing F2 on the keyboard. Renamed columns will be included in exported files and generated reports.

Click on the Export button to display a dropdown menu with the export options. You can export the selected results or line results to a .csv or a .txt file. 

You can set the Test Suite software to automatically calculate the Average/Max/Min/Standard Deviation values of all relevant runs by ticking the selection box next to the run number.

Once you have selected more than one result, the average, maximum and minimum values will be displayed. Once you have selected more than two results, it will also display the standard deviation of the selected runs.

If you select the tick box next to the Avg, Test Suite will add a moving average ‘best fit’ curve to all of the selected runs.

If you have specified Interim result(s) in the Test Configuration these will be displayed in the Test Results area. 

The Columns setting will display each interim result as a column on the right-hand side of the results table, in the order it was specified in the settings. If multiple At or Between conditions are met in a run, Test Suite will only display the first result.

The Separate Table setting will display the interim results from a selected run in a new window in the Test Results area. If you select multiple runs, the window will display the interim results from the last selected run. In addition to the interim results, the start conditions will also be displayed.

Change a Channel

You can change the channel used for interim result(s), by selecting the column header for the required result and clicking on the channel name in the Data Column section on  the Test Setup tab or right-clicking on the column header and and selecting the channel name from the dropdown menu. Both options will display a list of all available channels you can replace with.

Add a Channel

You can also add columns to the interim result(s) by selecting a result header and clicking on the Add button in the Data Column section on the Test Setup tab or by right-clicking on the result header and and selecting the Add option from the dropdown menu. Both options will display a list of the available channels you can select to display as a results column associated to that particular interim result.
