Key Message

For Educators:

Learning is a constant process. Amidst inevitable circumstances, the Department of

Education extends its resources and looks for varied ways to cater to your needs and to

adapt to the new system of Education as a fortress of the Learning Continuity Plan. One of

the probable solutions is the use of Teacher-Made Educational Modules in teaching.

You are reading the Electrical Installation and Maintenance for Grade 8: First

Quarter Alternative Delivery Mode (ADM) Module on “Perform Mensuration and

Calculation” as written and found in the Competency-Based Curriculum – Strengthened

Technical-Vocational Education Program.

The creation of this module is an effort of competent trainers from Bitoon National

Vocational High School of the Department of Education-Cebu Province during this

pandemic period. In addition, this module is meticulously planned, organized, checked, and

verified by knowledgeable educators to assist you in imparting the lessons to the learners

while considering the physical, social, and economic restraints in the teaching process.

The use of the Teacher-Made Educational Module aims to surpass the challenges of

teaching in a new normal education set-up. Through this module, the students are given

independent learning activities, which embodies in the Most Essential Learning

Competencies based on the K-12 Curriculum Competencies, to work on in accordance with

their capability, efficiency, and time. Thus, helping the learners acquire the prerequisite 21st

Century skills needed with an emphasis on utmost effort in considering the whole well-being

of the learners.

As the main source of learning, it is your top priority to explain clearly how to use this

module to the learners. While using this module, learner’s progress and development should

be recorded verbatim to assess their strengths and weaknesses while doing the activities

presented independently in the safety of their homes. Moreover, you are anticipated to

persuade learners to comply and to finish the modules on or before the scheduled time.

For the Learners:

As a significant stakeholder of learning, the Department of Education researched and

explored innovative ways to address your needs with high consideration on social,

economic, physical, and emotional aspects of your well-being. To continue the learning

process, DepEd comes up with an Alternative Delivery mode of teaching using Teacher-

Made Educational Modules.

TYPES OF ELECTRICAL MEASURING INSTRUMENTS

There are types of measuring tool which are commonly used to perform electrical work.

There are two ways on how tools can be utilized. Tools like vernier caliper, metric rule, steel

rules are tools used to perform layout and installation of a particular wiring materials. The

tools like multi meter, clamp meter, electric meter are common examples of tools used for

measuring electrical magnitude like the voltage current resistance or even the power

consumption of particular electrical appliances.

Multimeters are very useful test instruments. By operating a multi-position switch on the

meter they can be quickly and easily set to be a voltmeter, an ammeter or an ohmmeter.

They have several settings called “ranges” for each type of meter and the choice of AC or

DC. Some multimeters have additional features such as transistor testing and ranges for

measuring capacity and frequency.

Choosing a multi-meter

The photographs below show modestly priced multi-meters which are suitable for

general electronics use. A digital multimeter is the best choice for your first multimeter. Even

the cheapest will be suitable for testing simple projects.

If you are buying an analog multimeter make sure it has a high sensitivity of 20k /V or

greater on DC voltage ranges. Anything less is not suitable for electronics. The sensitivity is

normally marked in a corner of the scale, ignore the lower AC value (sensitivity on AC

ranges is less important), the higher DC value is the critical one. Beware of cheap analogue

multimeters sold for electrical work on cars because their sensitivity is likely to be too low.

Clamp meter is another type of measuring instrument which is specialized to measure

the value of electric current indirectly in an electrical circuit. This can also be a voltmeter,

and an ohmmeter. They have several settings called “ranges” for each type of meter and the

choice of AC or DC. It is also available either in digital type or analog type. (See picture at

next page)

Digital multi meter

Electric meter is an electrical device used to record the amount of electrical energy

consumed by an appliance or electrical system in a particular period of time

Insulation tester (megger) is an electrical measuring instrument intended to measure

the insulation resistance of electrical conductor. It is particularly used to detect the condition

of the coil of an electric motor. Below are pictures of a digital and analogue type insulation

tester.

The steel rule is considered to be the most convenient size to carry around. Many steel

rules have a "hook" feature that provides an accurate "stop" at the end of the rule. This can

be used to set calipers, dividers, etc. and to take measurements where it is not possible to

make sure that the end of the rule is even with the edge of the work. Some workers refer

steel rules as "machinists scales."

Metric rule is a tool used measure short and long distances. It is very important when

performing a layout and installation of electrical wiring fixture.

Caliper rule can be either vernier or micro meter. These tools are commonly used to

measure the diameter of a wires or thickness of steel plates . It can also be used to measure

the inner distance of a hole.
