Which multimeter, digital or analog, is better suited for use by electricians?
The multimeter is one of the commonly used electrical tools. There are two common types of multimeters on the market: pointer multimeters and digital multimeters. Which of these two is more suitable for electricians? Some people say to use numbers, some say to use pointers. Let's talk about this issue:
1. Each display method has its own strengths:
What is the reaction of many people when they see a digital multimeter? You will definitely think, wow, how good this multimeter is, it can be directly displayed in numbers after the measurement, and I don’t need to read it, how convenient! Well, this sentence was heard by an electrician who likes to use an analog multimeter, and he retorted. The advantage of the pointer table is that its pointer swings, which can very intuitively reveal the property changes of the measured object, which is more convenient than the digital table.
From the above point of view, it can be said that they are indistinguishable. However, digital watches also have a more prominent feature, that is, they can generally be made compact and portable, which is slightly better than pointer watches. As for the backlight problem, I think there are some better pointer watches, so that doesn't count.
2. The design uses are different:
Generally speaking, everyone subconsciously thinks that digital multimeters are tools suitable for measuring precision instrument components. Compared with pointer multimeters, the accuracy of digital multimeters is relatively intuitive and more accurate for applications such as small overload. The pointer multimeter is suitable for measuring large overloads (this has something to do with the working principle of the pointer). So it depends on the nature of the electrician's work and what the common measurement objects of the multimeter are. As for the problem of resistance to falling, I personally think that the digital watch is slightly better. After all, the swinging pointer is a precise and flexible physical device.
