Test control
Before starting a test run, select the desired test and be sure to save any changes to test configuration.
Enter the data file name and description. This information cannot be changed once a test is running.
If defined, the Test Duration parameter determines the duration of the test run in seconds, after which time the test run automatically stops. Show or hide this parameter in the Test section of the System Preferences.
To start the selected test, click Start. To stop the current test run, click
Stop.
Any user with privileges can stop a test run. The user who started the test need not be the same user who stops the test.
During the test run, the following run statistics display in the task pane:
Shunt control allows installation and removal of shunt resistors during a test run. If the current test contains one or more MX1615B-R bridge channels, click Shunt....
To install a shunt, select Normal or Opposite shunt mode.
NOTE
The Normal mode is based on the System Preferences Bridge shunt polarities parameter unless the bridge channel is configured to use the internal shunt resistor scaling mode. In this case, the Normal mode is the polarity defined in the sensor scaling configuration.
NOTE
Shunt polarity is in terms of the electrical units of mV/V. If the sensor scaling slope is negative, the shunt polarity in physical units is in the opposite direction. For example, the Up Scale option results in a negative swing in the physical units output data.
To remove a shunt, select Remove shunt.
All shunt resistors are removed at the start of a new test or new display mode.
NOTE
The Shunt Control dialog can remain open while still navigating the web application and closes automatically at the end of the test run.
Interactive triggers provide a means to manually trigger computed channels and Data Modes during a test run. Set up interactive triggers through the Interactive Trigger computed channel.
If the current test contains an Interactive Trigger computed channel, click Trigger....
Select a trigger index to set the trigger to TRUE. To invert the trigger logic, select the Invert trigger parameter when adding or editing the computed channel. Triggers not defined in the test setup are disabled.
NOTE
The Trigger Control dialog can remain open while still navigating the web application and closes automatically at the end of the test run.
The charts panel provides for the display of live channel data. A test must be running to view charts.
To create the first chart, select the desired channels from the Channels list. To add a new chart, drag a channel onto an empty area of the charts panel. Add channels to an existing chart by dragging a channel onto the chart window or by clicking the chart window and selecting channels from the Channels list.
TIP
Change chart options including the default chart type and size in User Preferences.
The chart windows may be resized, repositioned, and configured as needed. To automatically organize the chart windows, click Organize. This toggles between cascade and tile modes. The chart configuration persists as long as the current test setup is selected and remains unchanged.
Chart configurations can be easily saved for use with future tests. The configuration stores the chart types, sizes, locations and channels. To manage chart configurations, open the charts menu by clicking the menu button or right clicking in the charts panel.
To save a configuration, click Save in the charts menu. To load a previously saved configuration, go to the Chart configurations option in the charts menu and click on the desired configuration. Configurations can also be saved under a new name (Save as...) or deleted as needed. To start with a blank charts panel, click New from the charts menu.
Saved configurations are available to any user with privileges to view the Test Control page.
