Test view

The Test view module displays all information regarding the selected test and allows to edit the measurement setup and settings. The view of every tab depends on the test itself. This section just gives a general overview, for a specific test refer to the specific manual of a test. As well as any other module the Test view can be enabled/disabled in the menu, placed anywhere, automatically hidden or fixed in its position and stacked with other modules.

Input#

The test input tab displays the tests user interface with input parameters the user is allowed to adjust.

Output#

Test output parameters#

The test output tab enables the user to define captions for output parameters. Additionally limits can be defined which later can be used as a break condition. The user can set the minimum, maximum and define a fail bin for each parameter that allows a statistical evaluation and analysis of the frequency of occurrence for specific failures. If the limit of a parameter is reached, Measmatic offers the following continuations:

• continue → Measurement will continue even if the limit is reached

• stop → Measurement will stop when the limit is reached

• ask → User interaction required to decide individually for each case

Calculations#

Calculations provide mathematic functionality to add abstract and complex functions into a test and create a referable variable. In the formula editor the user can select from predefined mathematic functions and all test variables to create a new formula. By clicking apply, the syntax is checked and a valid formula will be added to the list.

Icon	Description
	Add a new formula to the table
	Remove a selected formula
	Move the selected formula up
	Move the selected formula down
	Opens the formula editor for a selected formula

Results#

The test results tab displays a table with all measured values. For each parameter and measurement run an array of values is accessible in the table. By double-clicking a cell the curve data of the selected parameter will be displayed in a separate window.

Diagram settings#

The diagram settings tab provides the setup of the diagrams to display the measured data in a chart. In the upper part of the tab, the user can define the diagram content. The bottom menu defines the layout of each diagram individually.

Icon	Description
	Add a new graph definition
	Remove a selected graph definition

Header	Description
X Axis values	Selectable parameters from a Dropdown menu that will be assigned to the X-axis
Y1 Axis values	Selectable parameters from a Dropdown menu that will be assigned to the Y1 axis
Y2 Axis values	Selectable parameters from a Dropdown menu that will be assigned to the Y2 axis
Diagram	Selectable diagram from a Dropdown menu
Show last n runs	If enabled, only the curves of the last n runs are shown in the diagram
Show error band	Displays the error band within the chart when enabled
Check error band	Compares the values from the measurement with the error band
Show reference curve	Displays the reference curve within the chart when enabled
Error X %	Allowed deviation from the X-Error band in percent
Error Y %	Allowed deviation from the Y-Error band in percent

Table: Diagram Settings - graph definitions

The error band columns are shown when "Error band options" is enabled.

The lower table defines the layout of each diagram: title and axis names. With "More options" enabled, further columns are shown, e.g. for the legend (show legend, placement, orientation, alignment), the title visibility and the limits for scientific notation.

Diagrams#

The diagrams tab displays all defined diagrams. The diagrams are selected by the tabs below the chart. Each diagram consists of the chart and the curve table on the right.

The toolbar on the left side of the chart enables tooltips and crosshairs, shows the axes settings, shows an overview chart and saves the chart as an image. The overview chart always displays the full range of the values and displays the selected view when zooming in or out. The curve table displays all curves of the diagram. Every curve can be enabled or disabled, referenced with a unique user-defined name and a unique line appearance. The table can be filtered by the name or parameter unit to display only the important curves.

Interaction	Function	Description
Left Click + move	Zoom In	Draw a rectangle within the chart to zoom min
Double Click	Auto-Scale	Reset the current zoom settings and activate auto scaling
Mouse Wheel	Zoom In/Out	Zoom in/out at the current cursor position
Right Click / toolbar	Enable tooltips	Enables/disables the tooltip that displays the measurement values within the chart at the current cursor position
	Enable crosshairs	Enables/disables a crosshair that displays the values of the current cursor position
	Show axes settings	Shows the axis setting menu that allows the user to disable auto-scaling, enter fixed min and max values of the chart and select either a linear or logarithmic scale
	Show overview chart	Shows/hides the overview chart
	Save as image	Stores the current chart in an image file according to the diagram export settings

Data export#

The data export tab defines export settings for the selected test. They work like the export settings of the project (see project settings), but only export the data of this test.

Function	Description
Add / Remove	Adds a new export setting or removes the selected one
Export setting name	Name of the export setting
Export script	Export script that defines the format of the exported data
Export data automatically after test execution	If enabled, the data is exported automatically after the test has been run

Table: Data export

The export settings of a test can also be executed manually via "Export using test preset" in the context menu of the test sequence (see test sequence).

Info#

The info tab shows general information about the test: type, description, revision, creation and modification date and the Measmatic version.

Formula editor#

In the formula editor the user can select from predefined mathematic functions and all test variables to create a new formula. By clicking apply, the syntax is checked and a valid formula will be added to the list.
