Working with the Log-Graph software 37 In offline mode, it is not verified whether a logger is connected and the port is disabled. In this case, only the display and evaluation functions are available under the menu item "Graphs". The switchover between the online and offline mode is performed in the menu bar via the menu item "View -> Online status" or in the toolbar via the button "Online .
LogGraph In log mode, the online view provides as additional information o the current record position and o a table with the current measured values, the minimum and maximum values. The table with the current values can be hidden, so reducing the data traffic on the port. In continuous log mode , it is not possible to synchronize the logger clock to a new setting.
Working with the Log-Graph software 39 Opening an archived file allows you to present its content as a table, a graph or a combination of both. The size of a newly opened window depends on the available graph area and uses by default about two thirds of the available width and two thirds of the available height. The size of each window can be tailored to your needs by dragging the edges with the mouse.
LogGraph The status line at the bottom of the window contains information about the current program status or the current operations.
Working with the Log-Graph software 41 3.6 Basic settings for the software operation The basic settings for the software operation are: the selected national language and the port used for operation The settings made are saved in the file .ini. 3.6.1 National language When you launch the software for the first time (after the installation), the PC specifications for the national language are first accepted from the installation.
LogGraph connected via an appropriate cable and powered on and it must be the only device currently connected (the other devices that are already connected must be turned off). All ports available for connection are searched. Ports that are already used by a device or are being used by another program are not searched. Each verification (port, transfer rate) requires about 2 seconds.
Starting the software 43 When you start the software, the program always searches for a connected logger. The following procedure is used: The program checks whether a logger is on the port that was last configured (entry in the file .ini) If the logger is not detected, an error message and a prompt appear. The latter asks you to connect a logger, to search for other ports on which the logger could be configured or to use the software in offline mode.
LogGraph The setup window contains four categories: Start/Stop/Measuring interval, Limit values, Display/Use and Names Load and Save: "Load and Save" allows you to load the old logger settings and save the current logger settings under any file name with the default extension "Set". All settings, except the absolute start and stop time indications, can be reused for subsequent setups.
Starting the software 45 described in the manual of the logger. Close Close allows you to quit the programming. If changes have been made and they have not yet been transferred to the logger, a warning message appears. Transferring the settings The settings made are sent to the logger and the setup window is closed. Only modifications are transferred. If no changes have been made, a corresponding message appears.
LogGraph performed via software (with a previous overwrite warning). Stop settings: The logger stop can be performed by simply pressing a button (start/stop button) or by using a Reed contact (option). This function can be disabled by unchecking the appropriate boxes.
Starting the software 47 Temperatures and humidity: The limit values are available as lower limit (Lo) or upper limit (Hi) for each measuring channel. With LOG-100, these are only temperature limit values, With LOG-110, these are temperature and humidity limit values. An external sensor can only be used when the "Use an external sensor" box is activated. The entered limit values are only used when the corresponding boxes are activated.
LogGraph beeper has not been disabled in the power saving options (Use the LED displays / Use the beeper).
Starting the software 49 Display/Use: The general settings for the logger operation are summarized in the category Display/Use. Logger time: The date and time of the internal logger clock are displayed. After clicking on the "Set" button, you can synchronize the logger time in the "Set the logger date and time" window. While recording, it is not possible to modify the logger time.
LogGraph remain blank (until you use the buttons again). LED displays green/red: The LED displays are only used when the "Use the LED displays green/red" box is enabled. The green LED always flashes at the sample rate when the "Flash in green at the sample rate" option is activated. With regard to the red LED, a flashing (in addition to the settings made under Limit values) can be activated, if errors have occurred in the logger or arming occurs.
Starting the software 51 Enter here any names that will allow you to clearly identify the logger. 4.3 Reading out the logger The readout of recorded data is launched via the menu item "Logger->Read out the data" or the shortcut key "Read" in the toolbar. First, the operational readiness of the logger is checked and all the logger parameters required for programming are retrieved. It takes a few seconds before all the data are uploaded and the readout window appears.
LogGraph The number of the available records, their start and stop time, the duration and the measuring interval set are displayed in the overview. Pressing the "Read out the Data" button causes the reading of the records to be started. In the lower part, the progress bar gives you an overview of the number of the already read records. It is possible to end prematurely the readout operation using the "Cancel ... " button.
Starting the software 53 The file extension is always. dbf (a file compatible with dBase III). The status information is saved under the same name but with the extension. set. Press "Save" to save the files. After saving the records, the values can be displayed in graphical/tabular form. For this purpose, click on "Display the graph". The data appear in a window of the graph area and can be further processed.
LogGraph "Close" allows you to quit the readout program. 4.4 Setting the logger time The synchronization of the logger internal clock is performed via the menu item "Logger->Set the time" or the shortcut key "Time" in the toolbar. While recording, it is not possible to modify the logger time. The window displays the current logger time and, for purposes of comparison, the current PC time. Depending on selection, o the PC time can directly be accepted or o set to any other value.
Starting the software 55 The categories "Hardware", "Status/Start/Stop" and "Alarms" contain information on the logger which was obtained by the same logger when recording (Status /Start/ Stop), or which is invariably linked to the logger (hardware). During the recording process, some values may vary. Clicking on "Update" allows you to update the information contained in the currently displayed page. When "Read all ... " is highlighted, all status information is read again.
LogGraph Status/Start/Stop Alarms/errors 4.
Starting the software 57 and the PC. Before executing the detailed tasks (programming, reading out the records, displaying the status, ...), the operational readiness of the logger is always checked and the complete set of parameters is always retrieved. The performed operations are displayed in the meantime. In case of communication errors, appropriate hints are issued. It takes a few seconds before all the data are uploaded and the window of the detailed task called up appears.
LogGraph 5 Presentation of graphs and tables As soon as the presentation of graph and/or table is opened, other processing points are available in the program menu. They are used to change the visualizations, to enter key values for presentation, and to export data or graphs from measurement tables.
Presentation of graphs and tables 59 5.1 Graph and table The presentation can be displayed either as a two-dimensional line graph or in 3D view. With regard to the 2D presentation the line widths can be changed. The table can optionally be displayed next to the graph or below the graph. Minimum, maximum and average value The minimum, maximum and average values of the recorded data are displayed next to the table (in 5.1.1) or above the table (for 5.1.2).
LogGraph 5.1.2 Table below graph The table is shown below the graph. The table height is always about one-third of the total window height.
