Frequently Asked Questions About the NI DIAdem Free Trial

  • The initial trial period is seven days, and the trial can be extended for an additional 45 days.

  • The DIAdem free trial gives you access to all the standard functionality in the DIAdem Professional edition.

  • Yes. If you saved your report files and scripts, you can pick up where you left off in the trial.

The DIAdem panels constitute the main level, where functions are grouped into related areas. The panels are arranged on the panel bar on the left side of the screen and are always visible, enabling you to switch from one panel to another.


DIAdem includes the following panels:

Use DIAdem NAVIGATOR to navigate in different file types and in different data stores, to search for data, and to drag and drop data into DIAdem.

Use DIAdem VIEW to view your data as curves or to edit single values in tables. You can add text, graphics, or videos to these displays.

Use DIAdem ANALYSIS to mathematically evaluate your data with standard functions from the extensive mathematics library or with your own formulas.

Use DIAdem REPORT to generate reports of your test data and analysis results.

Every DIAdem panel provides exclusively the functions the panel needs to fulfill the allocated sub-task. When you select a DIAdem panel, the group bars, function groups, and menus appear for quick access to the functions you need. Each DIAdem panel has its own group bar to the right of the panel bar. Click a function bar button in the group bar and select the function you want when the function group opens. The workspace also changes with the DIAdem panel and displays a folder hierarchy or a worksheet. Each panel has its own toolbar and context menus, which contain frequently used functions.

All the panels work with the data you load into the Data Portal. DIAdem VIEW, DIAdem ANALYSIS, and DIAdem SCRIPT can modify data and store the results in the Data Portal. 

DIAdem Functions

DIAdem VIEW panel structure with expanded function group

When you click a panel, the respective group bar appears next to the panel bar. This second level contains groups of related functions. Click an item on the group bar to open a function group and select a function. For example, you can select worksheet partitions in DIAdem VIEW, axis systems and tables in DIAdem REPORT, or select mathematical functions in DIAdem ANALYSIS. 


DIAdem NAVIGATOR

Use DIAdem NAVIGATOR to search for data and to load data selectively or completely into the Data Portal, to register data, to import data, and to save data selectively or completely. Navigate in data files, file folders, and databases to find your external data. The properties display shows the properties of a selected data set. To search for specific data, define a query in the search.


You can use the search bar to find data based on the file, group, and channel names and properties. When you find the data you want to use, drag and drop it to the Data Portal.


DIAdem VIEW

You can use DIAdem VIEW to inspect, measure, and edit the data of the Data Portal. Curves in 2D axis systems give you an overall view of the channels. You examine the curves with a cursor, zoom curve sections, and delete or replace curve points. List numeric channels, waveform channels, time channels, and text channels in channel tables where you can view and edit single values. 


If you modify curves or edit channels, DIAdem saves the changes in the Data Portal. If you record a video of a test while recording data, you can compare the video with the data, which is displayed as curves. You can illustrate the view of your data with diagrams and text. You can also project your data as color shading or deformation onto a 3D model of the test object. Use contour displays to display and analyze 3D data as characteristic diagrams. Use map displays to explain geographical data.


Select a worksheet partition in the group bar to align the axis systems, channel tables, and text boxes in the worksheet. The function groups offer different combinations of worksheet partitions. A VIEW layout may contain several worksheets with different views of your data. Select Insert > Worksheet to create a new worksheet. The toolbar contains various graphics cursors and cursor types for inspecting curves and accessing characteristic curve points. The toolbar also contains the buttons for enabling and disabling the coordinates window, for defining the curve display, and for loading and saving layouts. You can print the current worksheet or transfer it to a report.


DIAdem ANALYSIS

With DIAdem ANALYSIS you analyze the data of the Data Portal mathematically to reveal correlations and to derive further information from the data.


DIAdem ANALYSIS contains extensive libraries with mathematical standard functions that are located in various function groups. The function groups include basic mathematics such as differentiation, signal analysis such as FFT, and 3D analysis such as isoline calculations.


To use a standard function, click the group bar button and select a feature in the function group that opens. Set the parameters for your calculation in the dialog box that opens. DIAdem stores the calculation result in new channels of the default group, in the Data Portal. You specify the default group in the context menu of the Data Portal structure view. If you select Store result in original channel in the dialog box, the function stores the result data in the original channels and overwrites the original data. If you call another standard function, DIAdem prompts you to apply the function to the results of the last calculation. You can use all the numeric channels, waveform channels, and time channels in the Data Portal to execute calculations.


The DIAdem ANALYSIS workspace shows you which calculations you have executed with which channels. The toolbar has a button that opens the Calculator. You can use the Calculator to run your own calculations with channels and to generate new channels. You can also use the Calculator to calculate and to display single values and to assign values to variables. The toolbar also contains buttons for creating and managing calculation templates which you can then execute repeatedly without much effort.


DIAdem REPORT

Use DIAdem REPORT to generate a report that documents measurement data and results. You can access all the data in the Data Portal and present the data in a variety of ways. You can use any combination of axis systems, tables, text, and graphics in a report. Axis systems display data in curves or bar diagrams, and tables list channel contents. You can label your report with text and comments and illustrate your report with graphics and lines.


The various graphical display objects are grouped into function bars: 2D and 3D axis systems, 2D and 3D tables, polar axis systems, graphics, and decorations. The respective function groups contain various prepared types of these objects.


A report may consist of several worksheets with different displays of your data. Select Insert > Worksheet to create a new worksheet. The toolbar contains functions for loading and saving layouts, and for printing the report. The toolbar also has functions for aligning selected objects, and for refreshing the report.


DIAdem SCRIPT

Use DIAdem SCRIPT to automate recurring processes, such as standard evaluations and serial evaluations in a script. Each action and function in DIAdem has a command. A script consists of a series of commands that DIAdem executes consecutively. The easiest way to generate a script is in Recording mode, which you can select to generate code in VBS or Python by recording in the script editor the commands and the variable assignments for each interactive editing step. You can edit, extend, save, and test the recorded script. You use scripts to complete complex operations at the push of a button, starting with data loading over data analysis to the finished report. You can customize DIAdem to meet user requirements.


Use DIAdem SCRIPT to automate recurring tasks with scripts—from loading, to analyzing, and finally documenting the data.
