Objectives
When you have completed the experiments in this manual and listened to the accompanying audio tape you will know:
• How to make AC and DC voltage measurements.
• How to make resistance measurements.
• How to measure circuit current.
• Which measurements are made in series and which measurements are made in parallel with the circuit.
Introduction
Please refer to the figures in this booklet as you listen to NRI's Action Audio Cassette, which you received as part of your training unit 4976K. Before you begin the tape, make sure you have your DMM handy.
The tape leads you step-by-step through the basic operation of your DMM. You'll be asked to perform various operations and to make visual observations with your DMM as you listen to the cassette--that's NRI's Action Audio Learning.
This Action Audio Learning Unit was written and produced by the NRI development staff for the exclusive use of NRI students. I think you'll find this NRI Action Audio Learning Unit an exciting way to learn electronics.

NRI Graduates Say... "Through NRI I not only received the experience I was looking for, I also gained the confidence I sought to return to college and upgrade my skills and further my career ambitions. I particularly enjoyed the way you structure the course into smaller sections; it provided me the opportunity to move through the lessons at my own pace without fear of missing something important.
I chose NRI because right from your first correspondence with me I felt as though I had to mail out my application right away It sounded so exciting, I couldn't wait to get started, which is what I did. I looked forward to each new lesson because it felt so good to read and comprehend almost immediately, and those times I didn't understand, after one or two re-reads, I got it. I only needed the help of an instructor once, but his reply was prompt and clear. I was almost sorry once I had completed the course, but I've since enrolled in college and my studies continue. Would I recommend NRI to others? I already have! I sing your praises often to workmates and I think a couple of them have applied.
So all I can say is thanks to you I am far better off than I was three years ago, and my future looks bright. I'm sure there are many others who feel as I do."
