The schematic symbols of logic gates used in digital circuits are shown.
Analog Ammeter Operation
By Terry Bartelt
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.
Review - Radial Drill Press Parts Identification
By Kelly Curran
This interaction tests the student's knowledge of parts on a radial drill press.
Print Reading: Step Block
In this animated print reading exercise, the learner calculates missing dimensions and identifies surfaces on projected views.
Parallel Resistance Practice Problems
By Patrick Hoppe
Students work practice problems in which the total resistance of the circuit is calculated. Feedback is provided.
Analyze a Part Drawing
By Glenn Sokolowski
In this interactive object, learners answer 25 questions regarding part or assembly drawings. The basic areas of blueprint reading are covered.
Selector Switch Labeling
In this animated object, learners examine the method of interpreting the truth tables for two-position and three-position selector switches on ladder logic circuit diagrams.
In this animated object, learners examine how PLC up/down-counters are used to control an automated parking lot gate.
PLC Timer Instructions
Learners examine the animated Timer-On Delay instruction and the Timer-Off Delay instruction of a PLC timer. A brief quiz completes the activity.
Equivalent Gates/Ladder Logic Circuits
By Terry Bartelt, Terry Fleischman
Learners will identify ladder logic diagrams and the logic functions they perform.
You'll focus on terminology related to designing a hypothetical program.
Nondestructive Examination Symbols
You'll learn to identify nondestructive examination abbreviations and they use in examination symbols.
