How to choose a multimeter? What is the best multimeter? What to observe when choosing a multimeter? In this article, I will show you the essential features that make this multimeter very useful. The primary focus of this article is mainly the structural characteristics of the equipment, so come on, guys!
Digital multimeter, how to choose?
We have already done several articles about multimeters here in the World of Electrical, if you want to know about the functionality, categories, comparisons with clamp meters and much more, it is worth checking out these other publications and training yourself further in your area.
Every time I talk about multimeters, several questions arise! The first tip I will give you is to compare the equipment, noting the positive and negative points of each option. So, let us now know the five main structural characteristics that I think it is essential that a multimeter has.
One function that is very useful in a multimeter is the backlight! It can be essential in emergencies. So choosing a multimeter with a backlight is one of the first tips, and I will now explain how this is a huge advantage.
Imagine that you are taking a measurement in electrical installation and suddenly a circuit breaker trips and everything goes dark? At that time, the multimeter’s backlight will be super important for you to continue your work, as shown in the image below.
And note that this is just one of the situations in which the backlight can be very important. Another example is when you need to take measurements in very bright locations, and the display light helps a lot in visualizing the analysis.
Multimeter: Stand for standing
This support is the second tip, and as much as it seems silly, you will notice the importance of this when you need it; that is, if you choose a multimeter without this support, you will have great difficulties in some situations like the ones we will quote now.
The bracket at the rear of the multimeter can be used in two ways. The first is to keep the multimeter upright, as the working position sometimes makes viewing the measurement very difficult.
In this case, if the multimeter were lying down, it would be almost impossible to visualize the measurement, so the support was already a great ally. The other function of this multimeter support is to fit it somewhere to keep your hands free, which indeed ends up making work and measurement much more comfortable.
Multimeter: Handle to carry
Keeping your hands free while working is essential to ensure agility, practicality, and safety! Therefore, the third tip is to choose a multimeter that has a place to put the carrying handle.
Not every multimeter has it, but I always prefer to buy a multimeter where I can put a carrying handle. See how a carrying handle makes travel much more comfortable, especially when working at height.
In addition to allowing more agility and freedom when carrying out work at height, there is also the issue of safety. In this type of performance, it is essential to keep all items tightly attached to the body, and with the multimeter, it would be no different.
Therefore, with the use of the handle, you have more practicality in handling the equipment and still prevent falls from the multimeter that can damage the computer or, even worse, hurt someone who is below.
Multimeter: Rubberized protection
Speaking of falling, the fourth tip is directly related to that! Always choose multimeters with rubberized protection, because this protection is crucial to ensure a long equipment life.
As much as you are careful and use the handle to transport the multimeter, eventually, the equipment may fall. Therefore, having rubberized protection dramatically reduces the possibility of your multimeter breaking or damaging.
Multimeter: Category and certification
The multimeter has to be safe! So, our fifth tip is about the multimeter category and its certification. What guarantees that a multimeter will be safe is if you are using it in the right category, but how do you know that?
The answer is quite simple! Every quality multimeter has marked the category of work on the body of the equipment and what certifications it has. In this multimeter in the example below, we can see that it meets category 3, in addition to having several certifications.
Therefore, always look at the multimeter and the equipment manual for the certifications it has. This is essential to ensure your safety, which, as we speak, must always come first.
