Proper selection of pointer multimeter and digital multimeter
1. Each display method has its own advantages: when many people see a digital multimeter, what is their first reaction? 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 biggest advantage of the pointer watch is its pointer swing, which can very intuitively reveal the property changes of the measured object, which is more convenient than the digital watch.
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 purpose is different: Generally speaking, everyone subconsciously feels that the digital multimeter is a tool suitable for measuring precision instrument devices, and for purposes such as small overload, the accuracy will be relatively relative to the pointer multimeter. Intuitive, more accurate. 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.
