E. 9 COMPUTER SYSTEMS SERVICING Quarter 2 Self-Learning Module 3 Measuring Tools Introductory Message For the Facilitator: Welcome to the (Technology and Livelihood Education 9) Self-Learning Module on (Measuring Tools)! This Self-Learning Module was collaboratively designed, developed and reviewed by educators from the Schools Division Office of Pasig City headed by its Officer-in-Charge Schools Division Superintendent, Ma. Evalou Concepcion A. Agustin, in partnership with the City Government of Pasig through its mayor, Honorable Victor Ma. Regis N. Sotto. The writers utilized the standards set by the K to 12 Curriculum using the Most Essential Learning Competencies (MELC) in developing this instructional resource. This learning material hopes to engage the learners in guided and independent learning activities at their own pace and time. Further, this also aims to help learners acquire the needed 21st century skills especially the 5 Cs, namely: Communication, Collaboration, Creativity, Critical Thinking, and Character while taking into consideration their needs and circumstances. In addition to the material in the main text, you will also see this box in the body of the module: Notes to the Teacher This contains helpful tips or strategies that will help you in guiding the learners. As a facilitator you are expected to orient the learners on how to use this module. You also need to keep track of the learners' progress while allowing them to manage their own learning. Moreover, you are expected to encourage and assist the learners as they do the tasks included in the module.  For the Learner: Welcome to the (Technology and Livelihood Education 9) Self-Learning Module on (Measuring Tools)! This module was designed to provide you with fun and meaningful opportunities for guided and independent learning at your own pace and time. You will be enabled to process the contents of the learning material while being an active learner.

The word “measurement” means determining a dimension, capacity, or quantity of an object, or the duration of a task. These measurements include whether a storage medium has enough space to store a file in its memory, current temperature, speed and performance of the CPU. Measuring tools A measuring tool is a device used to calculate a measurable quantity. It is also used to take a count of quantitative data, such as weight, length, time and temperature. Rulers and scales are two common types of measuring tools used in Computer Aided Design (Auto-CAD). The types of rulers include yardsticks and tape measures, that can measure different distances. Rulers are useful because they can have multiple measurement systems, such as metric and imperial units which are simple to use because it has marks denoting subdivisions. On the other hand, the instruments used to measure any quantity is called measuring instruments. It measure the basic electrical quantities, such as voltage and current. Multimeter is the most commonly used instrument in computer technology to measure the quantities such as voltage, current, and resistance one at a time. It can be used to measure DC & AC voltages, DC & AC currents and resistances of several ranges. Types of Basic Measuring Instruments The basic measuring instruments are classified into two: 1. Voltmeter 2. Ammeter Voltmeter It is a measuring instrument which measures the voltage across any two points of an electric circuit. The units of voltage are volt and the measuring instrument is meter. Hence, the word “voltmeter” is obtained by combining the two words “volt” and “meter”. We can classify the voltmeters into the following two types based on the type of voltage that it can measure: 1. DC Voltmeter- measures the Direct Current voltage across any two points of an electric. https://www.tutorialspoint.com/electronic_measuring_instruments/measuring_instruments.htm 2. AC Voltmeter- measures the AC voltage across any two points of an electric circuit. https://www.tutorialspoint.com/electronic_measuring_instruments/measuring_instruments.htm Ammeter It is a measuring instrument which measures the current flowing through any two points of an electric circuit. The unit of current is ampere and the measuring instrument is meter. The word “ammeter” is obtained by combining “am” of ampere with “meter”. Ammeter can also be classified into two types based on the type of current that it can measure: 1. DC Ammeter-can be used to measure the DC currents from 0 to 50 amperes. https://www.tutorialspoint.com/electronic_measuring_instruments/measuring_instruments.htm  2. AC Ammeter-measures the AC current that flows through any two points of an electric circuit from 0-100 amperes. https://www.tutorialspoint.com/electronic_measuring_instruments/measuring_instruments.htm CLASSIFICATION OF MEASURING INSTRUMENTS The measuring instruments are classified into three types: 1. Electrical measuring instruments- are used for measuring electrical quantities such as current, voltage, power, and others. The good examples of electrical instrument are ammeter, voltmeter and wattmeter. https://www.pinterest.ph/pin/582794008007842859/ 2. Mechanical measuring instruments- are used for measuring the physical quantities which have static and stable condition. https://www.howmechanismworks.com/2017/09/top-20-interview-questions-on.html 3. Electronic measuring instruments-are used to measure anything that gives quick response time. This electrical and mechanicals instrument provide quick response as compared to the mechanical and electrical instrument. https://www.elprocus.com/types-of-electronic-testing-equipments/  ACTIVITIES Activity 1: Directions: Arrange the jumbled letters to form a word. 1.
