The document provides a comprehensive overview of multimeters, essential for anyone working with electrical and electronic circuits. It details the two main types of multimeters (analog and digital), their components, and how to perform measurements effectively. Additionally, it emphasizes the importance of proper use and interpretation of readings for troubleshooting electrical issues.

10. QUESTION:
WHAT DOES THE PICTURES
DEPICT?
WHAT IS COMMON WITH ALL
THE PICTURES SHOWN?

11. KNOWING FUNCTION OF MULTI
TESTER AND THOROUGH
UNDERSTANDING AND
ACCURATELY INTERPRETING
MULTIMETER READINGS IS
ESSENTIAL FOR ANYONE
WORKING WITH
ELECTRICALAND ELECTRONICS
CIRCUITS AND SYSTEMS.

12. WHETHER YOU'RE A PROFESSIONAL
ELECTRICAL AND ELECTRONICS
SERVICEMAN/TECHNICIAN, AN
ELECTRICAL/ELECTRONICS STUDENT, A
COMPUTER TECHNICIAN, ROBOTIC
PROGRAMMER, AN ELECTRONICS
ENTHUSIAST, OR JUST SOMEONE TRYING
TO TROUBLESHOOT A HOUSEHOLD ISSUE,
THE ABILITY TO USE AND INTERPRET
MULTIMETER MEASUREMENTS IS A
FUNDAMENTAL SKILL.

13. WHAT IS
MULTIMETER?

14. WHAT IS MULTI-METER?
A multi-meter or a multi-tester, also
known as a VOH (volt-ohm-milliameter),
is an electronic measuring instrument
that combines several measurement
functions in one unit.
A typical multi-meter can measure
voltage, current, and resistance.

15. TYPES
There are two basic types of multimeters:
A. analog multimeters
B. digital multimeters

16. ANALOG

17. DIGITAL

18. WHAT IS THE MAJOR DIFFERENCE
BETWEEN ANALOG AND DIGITAL MULTI-
TESTER?

19. An analog multimeter uses a needle
that moves along a scale to indicate
the measurement.
A digital multimeter uses a
numeric display to show
the exact value of the measurement.

20. PARTS OF ANALOG MULTIMETER

21. PARTS OFANALOG MULTIMETER
This is the
needle-shape
rod that moves
over the scale
of multimeter

22. PARTS OFANALOG MULTIMETER
This part which
is also known
as the dial or
infinity knob. It
allows you to
adjust the
pointer to the
infinity/zero
position of the
scale.

23. PARTS OFANALOG MULTIMETER
The “zero
adjustment knob
of analog
multimeter is a
control mechanism
used to calibrate
the meter’s pointer
to read exact
reference point of
zero.

24. PARTS OFANALOG MULTIMETER
To perform a zero
adjustment is a
must when
measuring
resistance.

25. PARTS OFANALOG MULTIMETER
How?
Set the meter range to
resistance function and
touch the two test
probes together to
create a zero resistance.
If the pointer does not
align perfectly with zero
on the scale, turn the
Zero Adjust knob until it
lines up precisely with
zero.

26. PARTS OFANALOG MULTIMETER
The “Range
Selector Knob”
also known as
selector switch. It
allows you to
adjust or select
the desired
setting during
testing.

27. PARTS OFANALOG MULTIMETER
In some analog
multimeter, the
continuity test
function is often
present. “BUZZ” It is
a feature that allows
you to quickly check
if an electrical circuit
is complete or there
is a break in the
circuit.

28. PARTS OFANALOG MULTIMETER
(ACV) or Alternating
Current Voltmeter
This range is a set of
measurement
options which allows
you select a specific
voltage range when
measuring ac
voltages.

29. PARTS OFANALOG MULTIMETER
(DCV) or Direct
Current Voltmeter
This range is a set
of measurement
options which
allows you select a
specific voltage
range when
measuring dc
voltages.

30. PARTS OFANALOG MULTIMETER
Voltmeter Scale
refers to the
range for reading
of voltage
measurements
during voltage
testing.

31. PARTS OFANALOG MULTIMETER
Ohmmeter Range
refers to the range
position when
reading
resistance. It is
basically
represented by X1,
x10x x100, x1k
and x10k

32. PARTS OFANALOG MULTIMETER
Ohmmeter Scale
refers to the scale
located at the
most of
multimeter scale
and used in
reading
resistance value.

33. TO CONCLUDE:
ALWAYS REMEMBER TO SELECT THE
APPROPRIATE MEASUREMENT MODE, ENSURE
PROPER CONNECTIONS, AND TAKE SAFETY
PRECAUTIONS WHEN WORKING WITH
ELECTRICITY.
WITH CONSTANT PRACTICE AND A GOOD
UNDERSTANDING OF THE PRINCIPLES BEHIND
MULTIMETER READINGS, YOU'LL BE BETTER
EQUIPPED TO DIAGNOSE AND RESOLVE
ELECTRICAL/ELECTRONICS PROBLEMS
EFFICIENTLY AND SAFELY.
