Which is more suitable for electrician operators, a digital or pointer multimeter?
A multimeter is one of the commonly used electrical tools. Currently, there are two common types of multimeter on the market: pointer multimeter and digital multimeter. Which of these two is more suitable for our electrical use? Some people say they want to use numbers, while others say they want to use pointers. Let's talk about this issue below:
1. Each display method has its own strengths:
What is the reaction of many people when they see a digital multimeter? I would definitely think, wow, this multimeter is so good. When measured, it can be displayed directly in numbers without me having to read it. How convenient! Well, this sentence was heard by an electrician who likes to use a pointer multimeter, and he retorted. The advantage of a pointer meter is that its pointer swings, which can intuitively reflect the changes in the properties of the measured object, and is actually more convenient than a digital meter.
From the above points, it can be said that it is difficult to distinguish between the two. However, digital watches have a more prominent feature, which is that they can generally be made very small and portable, which is slightly better than pointer watches. As for the issue of backlighting, I think some better forehead gauges are also available, so that's not a big deal.
2. There are differences in design purposes:
Generally speaking, subconsciously, people tend to think that digital multimeters are suitable tools for measuring precision instrument components, and for applications such as small overloads, their accuracy is relatively intuitive and more accurate compared to pointer multimeters. People think that pointer multimeters are suitable for measuring large overloads (which is also related to the working principle of pointers). So it also depends on the nature of the electrician's work and the commonly used measuring objects of the multimeter. As for the issue of resistance to falling, I personally think a digital watch is slightly better, after all, the swinging pointer is a precise and flexible physical device.
Or do carrots and vegetables have their own preferences, but what if it's a junior electrician? Based on the characteristics of the pointer multimeter, the author believes that it is more suitable, although it is relatively cumbersome and not intuitive enough. However, our goal is to learn and facilitate understanding of the numerical changes of the measured object, so it is still recommended for beginners to use.
