Technical data

Introduction

The purpose of this lab book is to provide hands-on experience to reinforce the electronic theory data

learned in this course. Students will improve their critical thinking skills by connecting circuits from

schematics, making measurements with a digital multimeter, organizing data, and analyzing

observations.

Most of the projects in this lab manual promote understanding of the intended points made by

performing calculations and making measurements. The results are then compared and conclusions

are drawn at optimum times during the project.

The projects in this lab manual are designed to help students develop and improve their abilities to:

• Follow instructions carefully.

• Make accurate measurements and calculations.

• Analyze technical data appropriately.

• Draw logical conclusions from their observations and calculations.

When performing each lab experiment make sure the meter and test instruments are set to the correct

function and range to ensure an accurate meter reading. There are also many calculations and

measurements in these lab projects that will require rounding of decimal points. To ensure a correct

answer, make sure each number is rounded to the nearest hundredth (two decimal places). For

example, if an answer calculates to 3.457 mA, the correct answer would be 3.46 mA. If an answer

calculates to 21.3523 k, the correct answer would be 21.35 k. If the answer is a whole number or if

the hundredths place is a zero, the extra zeros do not need to be added. For example, an answer of 10

volts does not need to be written as 10.00 V.

The answers must also be written in metric prefix form with the correct unit label. For example an

answer of 11270  should be written as 11.27 k. An answer of .482 A should be written as 482 mA,

etc.

For your convenience the Ohm’s Law formulas have been added toward the back of this lab manual.

Also included is an instructor sign-off sheet. Have your instructor initial and date this sheet in the

appropriate location when the corresponding project is correct and complete. This will help both you

and your instructor track your progress throughout the experiments.

We wish you great success during these hands-on experiences and hope that this manual will be both

interesting and educational as you prepare to enter the technical world of electronics
