How to use Analog Multimeter

Jun 13, 2020
Hi blogger fans, In this blog post we will learn about analog multimeter we will study its principle of working and we will see that how to use analog multimeter for measurement of voltage, current, Ohms, Resistance, and Continuity or Beep Testing in the mobile phone repairing field. so let us start learning.

Analog Multimeter Reading

Analog multimeter is most commonly used by mobile engineers and technicians in the mobile phone workshop and for the repair of mobile phones and smartphones.

best analogue multimeter
Now this best analog multimeter as the name suggests that it is a multimeter multi means that many and meter means measurements so this analog multimeter is an instrument that is used for making
multi measurements on the mobile phone and its PCB. various types of measurements can be done with analog multimeter sanwa. these measurements include the measurement of dc current and resistance in the area of mobile repairing. the analog multimeter can measure online voltage and offline resistance of various ranges on the mobile phone PCB. that is the definition of the best analog multimeter. Now let us understand how we can use the analog meter and what are the safety features that you need to keep in mind.

Analogue and Digital Multimeter Difference

comparison between analog and digital instruments
advantages and disadvantages of analog and digital multimeter

As we know there are two types of multimeter. 
  1. digital multimeter 
  2. analog multimeter 
The difference between these two multimeters is that digital multimeter is going to give us the output in the digital form whereas the analog multimeter gives the output in the analog form. Today we live in a digital age and mobile phone technician always wonder why do I need to use an analog multimeter to diagnose faults in mobile phone PCB when I can have a digital multimeter well there are some things that an analog multimeter can do that a digital multimeter can't. I hope you understand the basics of What is multimeter and its types? and we'll demonstrate that as we go through this article so read it completely.

definition of ammeter

and the instrument which measures resistance is called ohmmeter. 

what does a reading of 0 ohms mean
ohmmeter definition and function

because the voltage is the unit for voltage is volt the unit for current is ampere and the unit for resistance is ohms so based on that instruments are called voltmeter ammeter and ohmmeter.

Analog Multimeter Probes

you need to understand what probes are. probes are also called analog multimeter leads. As you can see in the picture
needle tip multimeter probes
fluke multimeter probes
There are two probes which are commonly used with all analog multimeter. they will be two leads one lead is red in color and the other lead is black in color. so red is taken as for the positive connection and black is taken as negative or analog multimeter use we will be having two leads red and black.

analog multimeter function
This is what we call the measurement scale on the analog meter. Now lets us understand what are these other readings are displayed on the measurement scale of analog multimeter. Now, on the left-hand side, you'll see something written as DCV.  this is the symbol of DC Current in the analog meter. when you turn meter knob to the left you will able to use the dc voltage meter on this Sanwa multimeter.

dc voltage meter
how to read dc voltage on an analog multimeter

where the range is between 2.5Volts to 1000 Volts. you can check DC voltage by placing the knob at the respective voltage point. if you have a smaller voltage to be checked you can place it at 10Volts and higher Voltages you can go on up to 1000 Volts to measure DC Voltage. On the right side of the meter, you see written as ACV. this is the symbol of AC Current in the analog meter. when you turn meter knob to the right you will able to use the ac voltage meter in this fluke analog multimeter.

How do you check AC voltage with a multimeter
where the range is between 10Volts to 1000 Volts. you can check AC voltage by placing the knob at the respective voltage point. for AC smaller equipment which requires 200 Volts or less, you can place meter knob at the 250 volts point and for Higher value, AC equipment you can measure using the 1000 Volts point. you can select ACV you can select DCV. AC means alternating current and DC means direct current. you can't get AC value on DCV. DC value on ACV.

How to read DC Voltage on Analog Multimeter

you can read battery voltage on the label of the mobile battery. Most mobile phone batteries are 3.7V or 3.8Volts. For how to use analog multimeter to test battery place the analog multimeter knob on DCV 10 volts. leads will be connected with the battery terminals positive to battery positive and negative to battery negative. follow the picture below to touch the probes of the multimeter on the terminal of the battery.
How to read DC Voltage on Analog Multimeter
How is DC voltage measured
the meter shows reading on the scale. is slightly from the AC scale. follow the picture below to analog multimeter reading.
How do I test if my multimeter is working
dc voltage reading

if the reading scale on the meter shows more than 3.7volts then the battery is fully charged. And if it is less than 3.7volts you will have to charge the battery with a charger. so that's how you read the DC scale here.

Note: If the battery is drained and showing 0 voltage the battery is dead.

How do you check AC Voltage with a multimeter

when you want to test and read a voltage if you don't know the voltage always select the highest scale but if you know your voltage select the appropriate scale, for alternating current examples, let's say I was going to work on 220 volts I would select the 250-volt scale put it on my AC if that's what we're going to read first and that is this scale right here the red one. so that's how you read the AC scale here.
AC voltage measurement
AC Volts
when AC voltage measurement is to be done then again we were having the two leads. place the meter knob on 250 volts ACV. one lead is connected to the ac phase and the other lead is connected with ac neutral wire on the electric socket. meter show reading on the reading scale. we will connect this to the main power plug to check the voltage. in your room, there are switches that are available on the board. for checking AC Volts you can plug points on this board.

how to measure ac voltage
Now, going further down on the right-hand side on the analog meter you'll see a few more micro readings that are multimeter resistance measurement principles. However, let us focus on only those readings that are very important during mobile repairing that we commonly take using an analog multimeter. Now let me show you how to measure ohms resistance on a multimeter to get reading in the felid of mobile repairing.

How do you read Ohms on an Analog Multimeter?

right below on the AC voltage, you'll see a few Ohm readings given there. This is where you place the dial to check the value of resistance.
how to measure ohms resistance on a multimeter
multimeter resistance measurement principle
when you check basic electronic components which ranges from 10 Ohms to 10 Kilo Ohms and that is how you turn the knob there you can place it at the respective point and check the resistance value.

then we'll take our ohmmeter range switch bring it over to the highest range our times 10,000 are being resistance and then we'd put our test probe together now the needle is going to fluctuate here
continuity test for cables
how to test continuity with analog multimeter
what we want to do is we want to zero this out so we have our zero ohm adjuster dial here. also called zero ohm adjustment knob.
How do you adjust the zero ohms on a VOM

you want to bring the zero ohm adjustment knob down until it zeros right to there and that way you've zeroed out your meter. the answer of How do you zero an analog ohmmeter.
How do you adjust the zero ohms on meter
multimeter continuity symbol
Now you have a question. What is the purpose of the 0 ohm adjust knob on an analog meter?
what is the purpose of range selector switch
analog meter
well if I want to get an accurate resistance reading I have to calibrate it the reason I have to calibrate the meter is that there's a battery in there and as the battery weakens it's going to change the values that it reads so now once we've got our meter zeroed out we can pick a range scale to go on depending on what we think that ohms value is. What does a high ohm reading mean? What is the purpose of range selector switch?
What is the purpose of range selector switch
range selector knob
we have our x one so if I came up to here and I'm on the 10 that would be 10 ohms when I'm on our x one if I was our x 100 that would be a thousand ohms and if I was our x 10000 that would be 100 thousand ohms so this is how you read it from right to left on the top. reading ohms value on the analog meter. the answer of What is the purpose of range selector knob on analog multimeter.
I hope now you have your two questions answers in this article how does a multimeter measure resistance and How to read resistance on a multimeter.

How to test Continuity with Analog Multimeter?

The next we will understand in the analog meter is where the continuity or beep testing comes and I give you the answer How do you check continuity with a multimeter. This is a very essential component when you do jumper testing on mobile phone PCB this is very essential testing when you are doing tracing mobile phone PCBs tracks. 
What is the symbol of continuity in a multimeter
wire continuity
On the analog meter, this point is called beep or Buzzer. when you place it here and touch the probes together, you will hear a beep sound.
what does a 0 reading on an ohmmeter mean
How do you check continuity with a multimeter
Now we try to understand what is the reason behind this beep sound. Why we need to do this continuity testing. To understand beep testing reason we have a house wiring continuity check example here in this blog post. when we are checking any wire with a multimeter and you want to check whether the wire is broken in-between. whether the wire is broken from inside. you will not be able to find it out looking at it from the outside. most peoples ask

How do I test my house wires with a multimeter? 

how to check continuity in a long wire. in the order to check a wire you need to check current continuity on it. that's why we use beep (buzzer) or continuity mode on the analog meter. to check wire we set meter knob at buzzer mode.
how to check continuity in a long wire
house wiring continuity check
then we touch meter both probes on both ends of the wire. which means you touch black to one end of the wire and red to another end of the wire.

how to check for a broken wire with a multimeter

if you hear a beep sound which means that the circuit is not open the wire is proper. typically broken wires are called open wires in the mobile repairing field.
principle of analog multimeters in mobile repairing
uses of multimeter

But, if you don't hear a beep it means the wire is broken from the inside. the method for continuity test for cables you see in this continuity test results is the same. you can use it for any wire testing. the method is the same while doing tracing on a printed circuit board (PCB) to check whether two points are connected properly. when setting analog meter knob on beep mode. testing anything it doesn't matter for you to place the meter negative probe to negative and positive probe to the positive lead.
I came across quite a number of questions about Analog Multimeter so that's why I publish this blog post. I hope you like it

What Android Operating System

Nov 28, 2019
what android operating system is and who made it
what is android
Today I am going to tell you about "what android operating system is"  and who made it? "Android operating system" is being used by 80% of people "worldwide". Android mobile phones were launched in the year 2003 and it is hugely used till the year 2008.
Nowadays, this is not only used in mobile phones but also in television smartwatches and cameras. It has more than 80% of shares in the global market

How was Android OS created?

The android operating system was developed in the year 2002 by four programmers:

  1. Andy Robin, 
  2. Rich Minar, 
  3. Nick Seras and 
  4. Chris White
These four scientists aimed to make an operating system for the camera but soon changed their minds to mobile due to less market value of the camera. It was only 5 months working on the Android operating system, they got an offer from Google to join.

who made the first android phone

In the year 2007, they launched the 1st android phone while it was a testing product to get the market and public value. The result was "positive" public liked the set very much and they get "huge feedback" At the time there were only two gigantic mobile companies windows and Nokia. Soon after Google launched android HTC. In 2011, the android operating system has used for television games as well as all the mobile phones. It's popularity grown-up from time to time. According to the Google survey, there are more than 2 billion people worldwide are using the android operating system. Android's logo was designed by graphic designer Elina Bloch. As you know all the android versions have always been launched on a specific desert name, the reason behind is very simple that all the version must be added sweetness in your life.
