So whenever you use them please observe the following rules: 1 Do not switch on (or connect) the power supply to a circuit until your connections have been checked by the teacher or laboratory technician. 2 Starting with all meters switched to the OFF position, select the highest possible range, and then carefully select lower ranges until a suitable defl ection (analogue instrument) or fi gure is displayed (DMM). 3 When taking a series of readings try to select a range that will accommodate the whole series. This is not always possible. However, if the range(s) are changed and the results are used to plot a graph, then a sudden unexpected gap or ‘ jump ’ in the plotted curve may well occur. 4 When fi nished, turn off and disconnect all power supplies, and turn all meters to their OFF position. 1.7 Communication It is most important that an engineer is a good communicator. He or she must be capable of transmitting information orally, by the written word and by means of sketches and drawings. He or she must also be able to receive and translate information in all of these forms. Most of these skills can be perfected only with guidance and practice. Thus, an engineering student should at every opportunity strive to improve these skills. The art of good communication is a specialised area, and this book does not pretend to be authoritative on the subject. However, there are a number of points, given below, regarding the presentation of written work, that may assist you. The assignment questions at the end of each chapter are intended to fulfi l three main functions. To reinforce your knowledge of the subject matter by repeated application of the underlying principles. To give you the opportunity to develop a logical and methodical approach to the solution of problems. To use these same skills in the presentation of technical information. Therefore when you complete each assignment, treat it as a vehicle for demonstrating your understanding of the subject. This means that your method and presentation of the solution, are more important than always obtaining the ‘ correct ’ numerical answer. To help you to achieve this use the following procedures: 1 Read the question carefully from beginning to end in order to ensure that you understand fully what is required. 2 Extract the numerical data from the question and list this at the top of the page, using the relevant quantity symbols and units. This is particularly important when values are given for a number of quantities. In this case, if you try to extract the data in the midst of calculations, it is all too easy to pick out the wrong fi gure amongst all the words. At the same time, convert all values into their basic
