Electrical Troubleshooting MS vs EPA 608 Pro

Totally FREE! No ads or pop-ups! How this App Works: This app has 17 different electrical problems that are randomly selected to provide a fun and challenging learning experience. It is certain to help you become more proficient in troubleshooting with a voltmeter. The motor starter is animated so that you can SEE the different contact configurations between forward and reverse. Another unique feature of this app is the ability to instantly switch back and forth between the control schematic and the real time PLC logic. There is also a "Troubleshooting Assistant" to help test the control circuit and find the problems. The app is initially in normal mode. This allows you to experience: - How a reversing starter works. - How to use the virtual voltmeter probes to measure voltages at various test points (small black squares, which turn red when the voltmeter makes contact with them) in the control circuit. - Analyze the PLC logic, when the starter is in various control modes Run (FWD & Rev), Off and Auto (FWD & REV). The HMI only has control in Auto. The selector switches work as indicated by control circuit. After the you understand how the motor starter works in the various control modes, you can check your troubleshooting skills by going to "Settings" (touch the 'More' button (at the top of the app) and then the gear icon) and selecting troubleshooting mode. Touch the "Arrow Back" icon to return to the control schematic. You will notice that the screen background has turned a light green, indicating that it is in troubleshooting mode and has a problem that needs to be found. Use the "Troubleshooting assistant" at the top, right side of the control schematic to help set the operator switches for testing. Use the voltmeter probes and PLC logic screen to identify the problem. Once you believe that you have identified the problem, touch "Problem Identified" button at the top of the app. A list of possible problems will appear. If you cannot determine the problem, at the bottom of the list, there is an item to provide the answer. If you desire to put the control system back in to normal (Non Troubleshooting Mode - No electrical problems) to learn more about how it is suppose to work, go to the settings section and unselect "Troubleshooting Mode". It is truly a great learning tool for anybody that wants to be able to fully utilize a voltmeter to troubleshoot a control circuit.

Getting your EPA 608 card comes down to four sections and one number: 18 out of 25 on each one. EPA 608 Pro gets you there with 1,025 questions, full exam simulators, and explanations that tell you why an answer is right instead of just marking it wrong. EXAM SIMULATORS Core, 25 questions Type I Certification, 50 questions Type II Certification, 50 questions Type III Certification, 50 questions Universal, 100 questions Core is required for every certification, so testing for one Type means sitting 50 questions rather than 25. The simulators match that. Each section is scored on its own, so you find out you are solid on Core and shaky on Type II while there is still time to do something about it. 1,025 QUESTIONS Seven categories and 41 subtopics: ozone science and federal regulations, refrigerants and refrigeration fundamentals, recovery and evacuation, safety and cylinders, and all three appliance Types. Every question comes with an explanation, and most of them name the exact mistake the question was written to catch. The 80 and 90 percent recovery rules, Table 1 evacuation levels, leak rate thresholds, the 200 pound line, 25 mm Hg absolute. These are the details people fail on, and they are covered. STUDY TOOLS Flashcards for every category, one fact per card Practice tests with answers and explanations as you go A diagnostic test that finds your weak spots Missed question review that keeps working what you got wrong Topic quizzes for any of the 41 subtopics Custom quizzes across whichever categories you pick A glossary for the abbreviations and jargon in the questions Progress tracking by category and subtopic WORKS OFFLINE Every question, explanation, and diagram lives on your device. Study in a mechanical room, a basement, the van, or anywhere else with no signal. FOR HVAC techs, apprentices, trade school students, and anyone testing for Core, Type I, Type II, Type III, or Universal certification.
