A multimeter is an electronic measuring device that combines the functions of a voltmeter, ammeter, and ohmmeter. It allows electricians to accurately measure voltage, current, and resistance. There are two main types: analog multimeters display measurements using a pointer on a scale, while digital multimeters display results numerically using an LED screen. A multimeter has various parts that perform specific functions like selecting the measurement type and adjusting readings.

1. PERFORM
MENSURATION AND
CALCULATION
(MULTITESTER)

2. Measuring Equipment with
the aid of electronic
measuring device gives an
electrician the exact
measure of voltage and
resistance of the electrical
components.

3. MULTITESTER
is an that
combines the
functions of
voltmeter,
ammeter and
ohmmeter.

4. KINDS OF
MULTIMETER

5. ANALOG
MULTIMETER
This measures
current,
resistance and
AC and DC
voltage.

7. DIGITAL
MULTIMETER
This is a tool
used to
measure amps,
voltage, and
ohms that
displays results
via an LED
display.

8. PARTS OF A VOM
FUNCTIONS OF EACH PART

10. INDICATOR POINTER
This is used as a
reference of where to
read the measurement

12. ZERO-OHM ADJUSTER
This is used to adjust
the indicator pointer to
zero when used as an
ohmmeter.

14. RANGE SELECTOR
This knob is used to
select the desired
function of the
multimeter.

16. PANEL
This is used to measure
voltage, current and
power line frequencies

18. NEGATIVE TERMINAL
This is where the black
probe is connected.

20. MIRROR
This is used to help
reduce parallax viewing
error.

22. ZERO-POSITION
ADJUSTER
This is used to adjust
the indicator pointer to
zero position at the left
side of the scale.

24. OUTPUT TERMINAL
This is used to buffer the
input for monitoring
purposes.

26. POSITIVE TERMINAL
This is where the red
probe is connected.
