Which is more suitable for electrician operators, a digital or a 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 types is more suitable for our electricians? Some people say they want to use numbers, while others say they want to use pointers. Let's talk about this issue:
1. Each display method has its own advantages:
What is the reaction of many people when they see a digital multimeter? I would definitely feel like, wow, this multimeter is so great. Once measured, it can be directly displayed in numbers without me having to read it. How convenient! Okay, this sentence was heard by an electrician who likes to use a pointer multimeter, and he retorted. The advantage of a pointer watch is that its pointer swings, which can intuitively extract changes in the properties of the measured object, and is actually more convenient than a digital watch.
From the above point of view, it can be said that it is difficult to distinguish between the two. However, a digital watch has a more prominent feature, which is that it can generally be made very small and portable, which is slightly better than a pointer watch. As for the issue of backlight, I think some better forehead pointer watches are also available, so that's not a big deal.
2. There are differences in design purposes:
Generally speaking, people subconsciously believe that digital multimeters are suitable tools for measuring precision instrument devices. For purposes such as small overloads, the accuracy of digital multimeters is also 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 a multimeter. As for the issue of resistance to falling, I personally think a digital watch is slightly better, as the swinging pointer is a precise and flexible physical device.
Or do carrots and vegetables have their own preferences, but what if they are a junior electrician? The author believes that the characteristics of a pointer multimeter are more suitable, although it is relatively cumbersome and not intuitive enough. However, our goal is to learn and facilitate the understanding of the numerical changes of the measured object, so it is still recommended for beginners to use.
