Testing electronic components is important to do correctly whether as a beginner or professional. There are criteria to follow which include following safety procedures, obtaining the job order, communicating the testing method, using the appropriate method, and recording the test process. The key steps are to obtain the job order which specifies the task, communicate the testing method to get approval, and use the most appropriate method based on the component's specifications. It is important to record the test process for evaluation.

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.
