In this screencast, learners read an explanation of the color code used on schematic diagrams for hydraulic circuits. Circuit examples for each color are shown.

In this learning activity you'll build a resistor's color code based on the bands.

In this animated and interactive object, learners use a color code to understand the operations of a hydraulic circuit. A brief quiz completes the activity.

This interactive learning object is designed to help learners memorize the color code used on some hydraulic schematic diagrams. Learners quiz themselves using electronic flashcards.

In this interactive object, students complete progressively more difficult exercises as a way to improve their ability to recognize resistor color code values.

Students examine how to interpret resistor color code bands to determine resistance values and tolerance ranges. This interactive learning object has audio content and includes exercises.

In this interactive activity, students read about the colored stripes on a resistor and interpret the placement of those colors to determine the value of four-band resistors.

Learners follow steps to convert numbers from Gray code to binary code. They then view steps to change binary values to Gray code numbers.

The learner will understand how to correctly wire a three-wire sinking and sourcing sensor.

In this animated object, learners study what happens if the maximum switching speed of a proximity sensor is exceeded.

Learners consider the factors that determine how well an inductive proximity sensor can detect an object. Those factors are size, position, and the material from which the target is made. A brief quiz completes the activity.

In this learning activity you'll review the historical progression of standards to learn what makes a good standard.

In this animated object, students examine the shades that result from mixing primary and secondary colors. Color tone and level are also defined.

In this learning activity you'll read descriptions of military standards, ANSI, ISO, calibration system standards and audit system reference standards. These topics would be important for the CQT (certified quality technician).

In this animated object, learners study the effects of making sensitivity adjustments to a capacitive sensor.

Students view maps and answer questions about the newest nine members of the European Union.

Learners view practical examples of how a Hall-effect sensor is used.

Learners identify the countries waiting to be admitted to the European Union. A map exercise completes the activity.

Learners examine the operation of various circuits that are internal to the capacitive proximity sensor.

Learners study how a hydrocarbon gas sensor operates and why it is used. A short quiz completes the activity.
