Hello guys, hope I meet you all going good?
I finally decide to purchase a new multimeter because I got tired and frustrated of not been able to successfully carry out a repair.
I know some might be wondering why I then called it an investment. Well, for an engineer, it is and you'll get to know why as you continue reading. A multimeter is one the essential tool an Engineer should own, most especially the electrical/electronic engineers. A multimeter is an electronic measuring instrument that constitute of several measurement functions in one unit, and a typical multimeter can measure voltage, current, and resistance. It comes in two types. The digital type and the Analog type. The one I got is the Digital type. As you'll all agree, the digital type is the best. Analog multimeter have several limitations. A multimeter is also called a multitester, so, wherever you see me make mention of multitester, I'm still referring to a multimeter.
I initially got my first multimeter when I was about starting my Industrial Training (IT) last year. I got it then because I knew I was going to be needing it while learning electronics. But it got stolen not quite long after I purchased it. The theft case was quite a funny one tho. Although before I got my personal multimedia then, I already learnt how to use a multimeter when I was undergoing my Student Industrial Work Experience Scheme (SIWES) three years ago. I got familiar with the functions, use, and care then.
Now, here's why I've said purchasing a multimeter is an investment to me. In general, we all know investment to a be "A placement of capital in expectation of deriving income or profit from its use or appreciation." So is the same as the investment I'm talking about in this context. As an electrical/electronic engineer, especially one who deals with maintenance and repairs (home appliances), in which I am one. To successful carry out any repair, a multimeter must be involved. You're thinking not in all cases right?
Well, whenever an appliance develops a fault, there are two ways of troubleshooting the fault as an engineer. One is by 'visual test', i.e. by checking through the appliance for any abnormality. And the second method is 'Master test', i.e. by checking each component terminals with a multimeter to examine if it input/output voltage and current are in accordance with its ratings.
But some individuals wrongly call this test a 'Meter test' due to the fact that it's a test carried out with a multimeter. So, even if the cause for the fault was identified with a visual test, a master test is still required to know what actually resulted to that fault only in mirror cases when it might just be a disconnection. So, it is always advisable to have a multimeter whenever you think of carrying out a repair on appliances.
The full content of the pack
Sorry I had to digressed a bit. It was to help you see things in the perspective I want you to see it. So as a potential engineer, my need for owning a multimeter can no longer be overemphasized. I've missed several chances of checking out home appliances repair jobs because I didn't have the tool I needed. Even to carry out personal repairs and build new circuits were problem to myself. But now that I've a multimeter, I would definitely be able to seize any chance the comes my way in checking out a home appliances repair services. So, on a long run, carrying out repairs with the aid of my multimeter and designing new circuits will earn me some money.
That's why I called purchasing a multimeter an investment on my path!!
Now to the content of the pack
An Operator's Instruction Manual
Here is an Operator's instruction manual. To be sincere I've never gone through an operator's instruction manual for a multimeter. But I'm hoping I won't be lazy, or rather feel reluctant to go through this specific multimeter operator's instruction manual. The operator's instruction manual contains all the general information about the multimeter such as; It model, specifications, functions, use, don't and does, etc. I know I'll definitely feel reluctant or find it boring reading the operator's instruction manual because I'm basically aware of these information regarding to a multimeter. But different product have different guide, so I might just be forced to.
Testing Leads
Here are the Test leads (a.k.a Probes). They basically servers as a connection between the device to be tested and the multimeter itself. One of its end will be plugged directly into the multimeter while the other end will serve as the testing end. The test leads are fragile and requires extra care while been handled. I knew this from my experience working with a multimeter.
The Multimeter
And lastly, the Multimeter. The multimeter as have said earlier on is an electronic measuring instrument that constitute of several measurement functions in one unit. And I also said that a typical multimeter can measure voltage, current, and resistance. A multimeter is just limited to measuring voltage, current, and resistance. There are more electrical/electronic quantities it can measure. So, for this particular meter I got, the quantities it can measure are as follows;
- DC & AC Voltage Measurement
- DC Current Measurement
- Resistance Measurement
- Diode Measurement
- Transistor hFE Measurement
- Temperature Measurement
- Audible Continuity Test
- Test Signal Use
- Battery Test
With all the above listed specification, you can tell it's a great multimeter for a potential engineer.
Putting the multimeter to test
I decided to carry out some test/measurement with the multimeter to confirm its working state. So I carried out three different test.
A DC voltage measurement
A resistance measurement
A continuity test
The first test is to measure the amount of voltage the battery can supply. The second test is to determine the value of the resistor. The third test is the check if there's in no unseen cut/break within the wire. At the end of each test, I was able to verify that the multimeter works perfectly fine.
Whenever you want to purchase anything, ensure it's something that with return value (not necessarily money) to you on the long run. Food is a case study 🙂. I'm looking forward to start working with my multimeter and hopefully earn something in return. Till then .....🖋

I think that here it is better not to delay necessarily to appeal to the experts if you need some serious comprehensive repair of household appliances. I remember trying to fix the stove myself and almost broke it to the end. Because the good thing is that then decided to look for somewhere to turn and found here https://jsbappliancerepair.com/simi-valley-appliance-repair help, they were able to come and help even in Simi Valley, so you can safely call them and they will promptly come and do as necessary.
