2. 10 Types of Electrical
Measuring Instruments and
Their Functions

3. Electricity is a flow that contains an
electric charge and is related to physical
phenomena. Until now, electricity had
various purpose in supporting daily
activities. In using electricity for your
daily life, you need a device to measure
electric voltage.

4. This type of measuring instrument has a
function to measure electrical quantities
which include:
• Current magnitude
• Endurance
• Electrical power
• Light power
• Voltage
• Frequency

5. Well, here are some of the types of
electric tools and their functions:

6. 1. Ohm Meter
Ohm meter is a device that
functions to measure the
amount of electricity from a
switch. According to ohm’s law,
the circuit of electric current is
directly proportional to the
voltage. This device focuses
more on resistance only.

7. 1. Ohm Meter
Ohm meters are divided into
two, one of them is analog ohm
meters. It is a simpler device
because it measures with a
needle, so you have to be more
precise in seeing where the
number is located.

8. 1. Ohm Meter
Digital ohm meter is an ohm
meter that provides more
accurate and detailed results.
The disadvantage of this digital
ohm meter is that it is difficult to
monitor when the voltage
fluctuates.

9. 1. Ohm Meter
This ohm meter also has the
function of knowing the damage
to an electrical circuit, so it can
help your work faster.

10. 2. Frequency Meter
The next type of electric
measuring instrument is the
frequency meter; this device has
a function to measure the
repetition of periodic movements
per second.

11. 2. Frequency Meter
The frequency meter also
consists of analog and digital,
where the analog meter
frequency works by manual
needle, and digital frequency
meters use more detailed
numbers.

12. 3. Volt Meter
The next measuring instrument
is a volt meter; this device has a
function to measure the amount
of voltage of an electric current
flowing per second.

13. 3. Volt Meter
This volt meter can measure the
electric voltage within a
predetermined maximum limit.
If the voltage exceeds the limit
it will cause damage to the
device.

14. 3. Volt Meter
Volt meters also consist of two
types, they are analog volt
meters and digital volt meters.
Analog volt meter works by
using a needle, while digital volt
meter can show you the number
in detail.

15. 4. Ampere Meter
The fourth type of electric
measuring instrument is the
ampere meter. This tool serves
to measure the electric voltage
current in a closed circuit. You
only need to attach this ampere
meter to the circuit of electric
current you want to measure.

16. 5. Watt Meter
The watt meter has a function to
measure direct current power.
This electric measuring device is
a combination of an ampere
meter and a volt meter.

17. 5. Watt Meter
Besides being able to measure
direct current power, the watt
meter can also measure the
power of a single phase
alternating current and measure
the power of a three-phase
alternating current.

18. 6. Megger
Megger stands for mega ohm
meter. Megger is a measuring
device to give you information
whether the conductor of the
instances has a direct connection.
Its general function is to measure
the insulation resistance of power
tools. The minimum is 1000 x
working voltage.

19. 7. Kwh Meter
Kwh meter works by using
magnetic field induction that
moves the aluminum plate. Kwh
meter is used to calculate
electrical energy consumption.
Meanwhile, the induction of kwh
meter is one of the type that is
useful for calculating household
electrical power.

20. 7. Kwh Meter
In general, this kWh meter is
easy to find in every house,
because this kWh meter is
required to know each electricity
consumption in households and
other buildings that use this
device. The usage will be a bill
that must be paid every month.

21. 8. Taco Meter
The next type of electric
measuring instrument is the taco
meter. This device has a function
to measure the engine rotation
of vehicles, such as cars and
motorbikes.

22. 8. Taco Meter
This device has a screen where
it displays the speed of the
vehicle. In addition, the taco
meter is also used to measure
the safe point that shows the
vehicle rotation speed.

23. 9. Oscilloscope
This device has a function to
map the signal from electricity.
This type of electric measuring
device consists of a physical
frequency component.

24. 9. Oscilloscope
Oscilloscope has measurement
results based on digital as well
as graphs that are easy to read.
There are so many benefits of
this oscilloscope, such as
differentiating AC and DC
voltages in electrical
components, knowing noise and
checking electronic circuit

25. 10. Avo Meter
Avo meter stands for ampere,
voltage and ohm meter. Avo
meter is a multifunctional
electric measuring instrument
for measuring electric current,
voltage and resistance of
electronic components.

26. 10. Avo Meter
Avo meter consists of analog
and digital. The analog avo
meter uses a needle as a pointer
to the result. Where the digital
avo meter displays a more
accurate number behind the
comma.
.

27. 10. Avo Meter
Those are some types of electric
measuring instruments that can
be used as needed. This need
can be adjusted by using the
required electric measuring
instrument.
