Learners follow steps to calibrate a transmitter used in process control applications. A brief quiz completes the activity.

Learners examine animations of the most common transmission signals used in automated systems, such as 4 mA to 20 mA, 3 psi to 15 psi, and 0 to 10 volts. A brief quiz completes the activity.

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

Learners observe that the volume of one mole of any gas is 22.4 L at standard temperature and pressure. An illustration shows that only the mass of the molar volume differs with the identity of the gas.

In this learning activity you'll identify and calculate the area under the normal curve specified by given z-scores.

In this learning activity you'll calculate the numeric value of an area when given the z scores.

The learner will recognize standard-position angles and find the reference angle for any standard-position angle.

In this animated and interactive object, learners view American National Standard and International Standard sheet sizes. A quiz completes the activity.

Learners convert a number from standard form to engineering notation.

As a welder, you'll need to know how to convert between standard and metric measurements. Try this activity to practice converting between these two measurements. A conversion chart is provided to help you complete this work.

Learners calculate gas density from the standard molar volume and observe how the density increases with the increasing molecular weight of the gas.

In this learning activity you'll explore normal distribution and enter values for the mean and the standard deviation of normally distributed data and observe the resulting changes in the shape of the normal curve.

Learners examine the proper way to set up standard and metric micrometers to measure the wear on a brake drum.

Students read about the basics of using an indicator.

In this learning activity you'll use the Empirical Rule to calculate the percentages of data between two data points.

Learners review guidelines for the proper use of a dial caliper. Illustrations appear throughout the learning object.

In this interactive object, learners examine simplified sampling plans and tables based on the ANSI/ASQ Z1.4 standard. An exercise completes the activity.

This learning object has been created to educate workers about the occupational risks of being exposed to bloodborne pathogens as described in the U.S. Occupational Safety and Health Administration (OSHA) 29 CFR 1910.1030- Bloodborne Pathogen Standard.

Students examine standard pressure in this interactive object.
