Interactive Lab Assistant: Current and voltage converters

The experiment instructions come in the form of an Interactive Lab Assistant course. This multimedia course is a step-by-step guide through the topic of modern energy systems. The fundamentals are conveyed using easy to understand animations. The Interactive Lab Assistant in conjunction with the SCADA Viewer constitutes a comfortable experimenting environment.

Special features:

• Interactive experiment setups
• Measured values and diagrams can be stored in the experiment instructions per drag and drop
• The SCADA Viewer can be started directly from the experiment instructions
• Includes questions with feedback and evaluation logic for progress monitoring
• Documents can be printed out for hardcopy of experiment instructions including solutions
• Labsoft browser, course software and SCADA Viewer
