DM2000 screenshot gallery

This page contains links to the Data Master 2000 screenshots and illustrates various features of Data Master 2000.

Data acquisition with DM2000 (22 929 bytes)

Several experimental facilities were successfully automated with DM2000 (including low-temperature spectroscopic and galvanomagnetic measurements). This picture demonstrates real data acquisition process: resistivity of carbyne samples measured in the wide temperature range from room to liquid helium temperatures. Data from experimental hardware recorded by special application running in the foreground window (see more details about data acquisition).

Script window example (7 734 bytes)

DM2000 includes two special windows that can utilize Windows scripting engines: minibrowser (scripts are invoked from HTML code) and script window. This tool especially convenient for debugging purposes: you can compile script and simply run selected procedure. Notice that more powerful and convenient script debuggers included in various Microsoft products.

HTML scriptlet in the Minibrowser (10 174 bytes)

DM2000 exposes its object model to any COM-compatible automation controller. For example, this screenshot demonstrates how to run HTML and script - based applications within DM2000 minibrowser window. This application ("scriptlet") can contain various UI controls, including ActiveX instrument drivers, and it has access to DM2000 windows, worksheets, data elements etc. See also Impedancemeter simulator page.

Carbyne Ro(T) and TEMF analysis (37 100 bytes)

This project contains conductivity and TEMF data for a series of quenched under high pressure carbyne samples. Sig(T) and TEMF(T) curves may be decomposed into several contributions with the specific nonlinear fitting procedure (see also next picture).

Fitting carbyne TEMF (14 709 bytes)

DM2000 includes 3 fitters: one linear ("exact" fitting: parameters calculated by solving a system of linear equations) and two non-linear (iterative, Levenberg-Marquardt algorithm): for arbitrary function and for lorentzian peaks (calculates initial parameter approximations). You have full control over the fitting session: you can manually set parameter values, fit only selected points, and do many other things.

Base line subtraction tool (13 331 bytes)

Microwave transmission spectrometer uses low-temperature bolometer instead of resonator cavity. This feature allows wide-band frequency measurements (typically 20-120 GHz for our generators), but the base lines for field scans become more complex. Usually it is necessary to subtract base line from MW transmission (or absorption) spectra for future fitting (see above). This picture demonstrates base line subtraction tool: you can see original curve (green, top pane), cubic spline calculated by manually created points (red) and result plot (bottom pane, blue) of subtracted spectra.

Plot series manager window (11 978 bytes)

Plot series manager window works as a detailed plot legend and allows user to apply standard Copy/Paste/Cut/Delete commands on the list of Series objects. With this tool, series management becomes more convenient, intuitive and "object-oriented".

Curve translation tool (5 858 bytes)

When you work with electrical contacts in the wide temperature range (1.7-300 K) you may frequently observe various contact instabilities. Sometimes your data seems to be multiplied by (approximately) constant factor, or linearly displaced, as shown at this picture. In this case you may easily "repair" your curve with curve translation tool: just select "bad" points and drag them at the right place.

MetaBase property pages (6 500 bytes)

MetaBase software briefly described at the MetaBase User's guide page. This picture illustrates how DM2000 MetaBase can interact with Windows shell: right-click associated with property page handler file icon, select "Properties" from the popup menu and get full information about this file. Note that property pages constructed manually from resources in DM2000 application.

DM2000 project loaded into Delphi 6 (25 986 bytes)

This picture illustrates development process with Delphi 6. You can see opened DM2000 main form, appropriate *.pas file loaded into editor window and code explorer. Enjoy!

DM 6.0 for MS DOS screenshot (27 008 bytes)

Note that DM2000 project has a long history: it was started at 1993! That's why its current version is 10.x.
