Using Blueprints to Troubleshoot a Defective Water Pump
In this simulation activity, an electrician troubleshoots a defective water pump that will not start. To find the problem, the learner selects the appropriate blueprints that must be referred to while performing the troubleshooting steps. Then safety protocols will be followed, such as making lockout-tag out installations and donning PPE items before taking measurements with a multimeter to locate the faulty component.
Using Blueprints to Troubleshoot a Defective Compressor Motor
In this simulation activity, an electrician troubleshoots a defective compressor motor that will not start. To find the problem, the learner selects the appropriate blueprints that must be referred to while performing the troubleshooting steps. Then safety protocols will be followed, such as making lockout-tag out installations and donning PPE items before taking measurements with a multimeter to locate the faulty component.
Learners read a description of the function of the coupling switch on an oscilloscope and how its setting affects measurements of DC, AC, and combined voltages. A brief quiz completes the activity.
Temperature Emissivity of Non-Blackbodies (Screencast)
Learners study the effect of reflected and transmitted energy on the measurement of emitted energy by a non-blackbody. A short quiz completes the activity.
Students follow the procedure to measure voltage with an analog voltmeter. They examine the use of the Function Switch and the Range Switch. A brief quiz completes the activity.
In this animated learning object, students view the operation of an oscilloscope that is used to measure AC voltages. A brief quiz completes the activity.
Learners examine dew point and the two types of humidity values, absolute and relative, along with the types of instruments used to measure them. The activity includes a video clip and a quiz.
Students examine the procedure to measure current with an analog ammeter. The use of Function and Range switches is explored along with reading the needle position on the meter scale. A brief quiz completes the activity.
