Provides a real-time diagnostic of a Dissolve Gas Analysis (DGA).

The UI is quite intuitive. Use only the mouse. The cursor acts as a toggle button. The first click activates the abacus, and lets you finely adjust the three parameters (C2H2, CH4 and C2H4). When you are done, you can freeze your settings by clicking a second time within the triangle area.

Of course, you can restart with another click and toggle again in active mode.

How can I use?

Can you please advise me on how to input the gas concentrations from an Excel file and get the "fault type" as an output?
If you have such a program to read excel file for gas values, determine the fault and to output the results (faults), can you please share and help.
