Config Tab

The Config tab provides access to all major LabOne settings and is available on all MFLI instruments.


  • define instrument connection parameters
  • browser session control
  • define UI appearance (grids, theme, etc.)
  • store and load instrument settings and UI settings
  • configure data recording


The Config tab serves as a control panel for all general LabOne settings and is opened by default on start-up. Whenever the tab is closed or an additional one of the same type is needed, clicking the following icon will open a new instance of the tab.

Control/Tool Option/Range Description
Config Provides access to software configuration.

The Config tab (see Figure 1) is divided into four sections to control connections, sessions, settings, user interface appearance and data recording.

Figure 1: LabOne UI: Config tab

The Connection section provides information about connection and server versions. Access from remote locations can be restricted with the connectivity setting.

The Session section provides the session number which is also displayed in the status bar. Clicking on Session Dialog opens the session dialog window (same as start up screen) that allows one to load different settings files as well as to connect to other instruments.

The Settings section allows one to load and save instrument and UI settings. The saved settings are later available in the session dialog.

The User Preferences section contains the settings that are continuously stored and automatically reloaded the next time an MFLI instrument is used from the same computer account.

For low ambient light conditions the use of the dark display theme is recommended (see Figure 2).

The Record Data section contains all settings necessary to obtain hard copies of measurement data. The tree structure (see Tree Selector section) provides access to a large number of signals and instrument settings. Use the View Filter in order to reduce the tree structure to the most commonly used nodes such as the demodulator sample nodes. Whenever the Record button is enabled, all selected nodes get saved continuously in MATLAB, comma-separated value (CSV), or other supported file formats. For each selected node at least one file gets generated, but the data may be distributed over several files during long recordings.

The files are normally saved to the internal storage of the MFLI or on a mass storage device connected to one of the instrument’s USB ports. In order to save data directly on the host computer, please install and run the LabOne Web Server on the host computer as described in Running LabOne on a Separate PC.

See Saving and Loading Data for more information on data saving. The quickest way to inspect the files after recording is to use the File Manager tab described in File Manager Tab. Apart from the numerical data and settings, the files contain timestamps. These integer numbers encode the measurement time in units of the instrument clock period 1/(60 MHz). The timestamps are universal within one instrument and can be used to align the data from different files.

Table 2: Config tab
Control/Tool Option/Range Description
About Get information about LabOne software.
Web Server Version and Revision string Web Server version and revision number
Host default is localhost: IP-Address of the LabOne Web Server
Port 4 digit integer LabOne Web Server TCP/IP port
Data Server Version and Revision string Data Server version and revision number
Host default is localhost: IP-Address of the LabOne Data Server
Port default is 8004 TCP/IP port used to connect to the LabOne Data Server.
Connect/Disconnect Connect/disconnect the LabOne Data Server of the currently selected device. If a LabOne Data Server is connected only devices that are visible to that specific server are shown in the device list.
Status grey/green Indicates whether the LabOne User Interface is connected to the selected LabOne data server. Grey: no connection. Green: connected. Red: error while connecting.
Connectivity From Everywhere Forbid/Allow to connect to this Data Server from other computers.
Localhost Only
File Upload drop area Drag and drop files in this box to upload files. Clicking on the box opens a file dialog for file upload.

Supported files: Settings (*.xml), software update (LabOne*.tar). Uploading software updates will automatically trigger the update process if the file is valid and has a different revision than the currently installed software.
Session Id integer number Session identifier. A session is a connection between a client and LabOne Data Server.
Session Manager Open the session manager dialog. This allows for device or session change. The current session can be continued by pressing cancel.
File Name selection of available file names Save/load the device and user interface settings to/from the selected file on the internal flash drive. The setting files can be downloaded/uploaded using the Files tab.
Include Enable Save/Load of particular settings.
No Include Settings Please enable settings type to be included during Save/Load.
Include Device Enable Save/Load of Device settings.
Include UI Enable Save/Load of User Interface settings.
Include UI and Device Enable Save/Load of User Interface and Device settings.
Include Preferences Enable loading of User Preferences from settings file.
Include UI, Device and Preferences Enable Save/Load of User Interface, Device and User Preferences.
Save Save the user interface and device setting to a file.
Load Load the user interface and device setting from a file.
Load From USB Load public SSH keys from the USB mass storage connected to the device. Uploading of SSH keys enables SSH access to the device.
Delete All Delete all public SSH keys on the device.
Time Zone Timezone offset from UTC (Coordinated Universal Time). Select the time zone in which the device is used. Settings, data and log files receive timestamps from this time zone. Requires a power cycle for changes to become effective.
Language Choose the language for the tooltips.
Display Theme Dark Choose theme of the user interface.
Plot Print Theme Dark Choose theme for printing SVG plots.
Plot Grid None Select active grid setting for all SVG plots.
Plot Rendering Select rendering hint about what tradeoffs to make as the browser renders SVG plots. The setting has impact on rendering speed and plot display for both displayed and saved plots.
Auto Indicates that the browser shall make appropriate tradeoffs to balance speed, crisp edges and geometric precision, but with geometric precision given more importance than speed and crisp edges.
Optimize Speed The browser shall emphasize rendering speed over geometric precision and crisp edges. This option will sometimes cause the browser to turn off shape anti-aliasing.
Crisp Edges Indicates that the browser shall attempt to emphasize the contrast between clean edges of artwork over rendering speed and geometric precision. To achieve crisp edges, the user agent might turn off anti-aliasing for all lines and curves or possibly just for straight lines which are close to vertical or horizontal.
Geometric Precision Indicates that the browser shall emphasize geometric precision over speed and crisp edges.
Resampling Method Select the resampling interpolation method. Resampling corrects for sample misalignment in subsequent scope shots. This is important when using reduced sample rates with a time resolution below that of the trigger.
Linear Linear interpolation
PCHIP Piecewise Cubic Hermite Interpolating Polynomial
Show Shortcuts ON / OFF Displays a list of keyboard and mouse wheel shortcuts for manipulating plots.
Dynamic Tabs ON / OFF If enabled, sections inside the application tabs are collapsed automatically depending on the window width.
Graphical Mode Collapsed Select the display mode for the graphical elements. Auto format will select the format which fits best the current window width.
Log Format .NET Choose the command log format. See status bar and [User]\Documents\Zurich Instruments\LabOne\WebServer\Log
CSV Delimiter Tab Select which delimiter to insert for CSV files.
CSV Locale System locale. Use the symbols set in the language and region settings of the computer Select the locale used for defining the decimal point and digit grouping symbols in numeric values in CSV files. The default locale uses dot for the decimal point and no digit grouping, e.g. 1005.07. The system locale uses the symbols set in the language and region settings of the computer.
Default locale. Dot for the decimal point and no digit grouping, e.g. 1005.07
