Criteria for Testing Electronic Components.pdf
- 3. OBJECTIVES At the end of the lesson, you should be able to: Determine criteria for testing electronic components, Plan an approach for testing components, Test the components, Evaluate the testing process.
- 4. TESTING ELECTRONIC COMPONENTS Testing of electronic components is the first thing that we do whether we are still a beginner in electronics or a professional. It is necessary for us to plan and know thoroughly the correct way to test the components and the right way to determine accurate test result most especially when troubleshooting, repairing and maintenance of electronic device like computer.

CRITERIA FOR TESTING ELECTRONIC COMPONENTS
- 6. Disconnect the power source before checking, servicing, repairing or installing electrical equipment and devices. Always select the higher value in Digital or Analog Multitester, and then, gradually reduce it to the proper value. Never try to work on electricity without proper guidance and care. Read all instruction and cautions and follow them strictly. 1. FOLLOW OCCUPATIONAL HEALTH AND SAFETY PROCEDURES
- 7. A job order is a form containing specifications of a task to do and it usually includes instructions, date, and time to execute the order, address or location of the worksite, the name of the client and his contacts, and the name of the technician. Either you’re a test personnel in an industry or a technician in a shop, testing always uses the job order or the client requirements as the guide. 2. OBTAINING THE JOB ORDER
- 8. Sample of a Job Order Form
- 9. If you are working in a manufacturing industry of electronics components, the responsible personnel or the supervisor in your technical department gives you the work instructions in a form of job orders to specify the task to do. On the other hand, testing on repair shops sometimes refers to job orders given by the clients or customers. It is the client who gives the job, but most of the time, technicians already know what to do if the shop is already following standardized procedures.
- 10. 3. COMMUNICATING OR REPORTING OF THE DESIRED METHOD TO USE. Before performing the desired method / procedure for testing the component, you must communicate or report it to the supervisor or to the person in charge to verify or approve the plan/procedure to ensure an efficient workflow and success of the testing procedure.
- 11. 4. USING THE APPROPRIATE METHOD When a method and tools are approved for testing, it is considered the most appropriate method and tools to use. The selection of the methods and tools is usually based on the component’s specification and manufacturer’s instructions. This is a standard practice among industries, which aims to produce quality services, efficient workflow, effective tools, and safe working environments.
- 12. 5. REC RDING THE TEST PROCESS The testing does not only require complying with the job order, consulting to the responsible personnel, selecting the efficient method, or preparing effective tools. It also requires recording the test process for evaluation purposes. The technician must identify or document the testing process performed and record technical problem encountered for an accurate data gathering and evaluation.
