In this screencast, learners follow steps to determine the proper starting belt length for a timing, flat, or v-belt drive.

Learners read an explanation of the RL time constant and examine the formula for calculating the instantaneous current value. The current is graphed as it climbs to maximum or drops to zero. Note* In the formulas in this module, the Greek letter epsilon should be the mathematical constant 'e'.

Understand the pseudocode structure of variable declarations, a vital component of programming computer and industrial applications.

Learners view the operation of a full-wave rectifier which has two diodes.

In this animated object, learners study how displacement level sensors are used to measure the level of liquid in a tank.

In this animated object, learners observe the operation of a J thermocouple with a cold junction. A table is used to convert the voltage it produces to a corresponding temperature. A brief quiz completes the activity.

In this animated learning object, learners examine how an ultrasonic flowmeter measures the flow of liquids through a pipe using ultrasonic sound waves. A short quiz completes the activity.

Learners study the method of using more than one track and quadrature modes to improve the resolution of an optical encoder. A brief quiz completes the activity.

In this animated activity, learners examine the operation of an ultrasonic sensor and the procedure to perform zero and span adjustments. A brief quiz completes the object.

Match the steps in the GCMS (gas chromatograph and the mass spectrometer) process with the correct stage in the procedure.

Review your understanding of fumes and particulates safety in welding.
