Students read how to set up the optical comparator edge detector in this interactive learning object.
The learner tests his/her ability to set up the optical comparator edge detector using a virtual simulation of the machine.
Learners examine the theory of operation for a combustible gas detector. A brief quiz completes the activity.
Learners examine how metal detectors function. This object includes animation and sound.
Learners study animations to see the connection between temperature and resistance as they examine the operation of an RTD. A table is used to convert resistance readings to the corresponding temperatures. A brief quiz completes the activity.
