Description

From the listing uploaded by “appupdater”.

This app is a simple utility/game for learning electrical troubleshooting with a voltmeter. A voltmeter is one of the most valuable tools that an electrical troubleshooter can use. This is because most electrical problems are loose connection (open circuits), shorted devices or operator errors (no electrical problems). There are ten circuits in each game. Each circuit consist of an "Open", "Short" or "NoProblem". Solve the problems of the ten circuits with the fewest number of tries and shortest amount of time. If you do well, you receive the prestigious certification of a "5 Star Troubleshooter". Are you a 5 Star Electrical Troubleshooter?
