Which is better for electrical operators, digital or pointer multimeters?
Multimeter is one of the commonly used electrician's tools, the current market common multimeter has two kinds: pointer multimeter, digital multimeter, and these two in the end which is more suitable for our electrician with it? Some people say to use digital, some people say to use the pointer. Here to talk about this issue:
1, the display each has its own strengths.
Many people see a digital multimeter, the reaction is what? Definitely think, wow, this multimeter how good ah, the amount can be directly with the digital display, do not need me to read out, how convenient! Well, this sentence was heard by the electrician who likes to use the pointer multimeter, he retorted. The advantage of the pointer table is that its pointer swing, which can be very intuitive to mention the properties of the measured object changes, but more convenient than the digital table Oh.
From this point of view, it can be said that it is difficult to distinguish between them. However, the digital table also has a more prominent features, that in general can be made very small and portable, which is slightly better than the pointer table. As for the backlight problem, I think some of the better amount of pointer table is also there, it does not count.
2,Designed for different purposes:
Usually, we subconsciously feel that the digital multimeter is suitable for measuring precision instrumentation devices from the tool, small overloads on this kind of use, relative to the accuracy of the pointer multimeter will be relatively intuitive, accurate some. And the pointer multimeter people think suitable for measuring large overload (this and the working principle of the pointer also has some relation to it). So it also depends on the nature of the electrician's work, how the multimeter is commonly used to measure things. As for the problem of drop resistance, I think the digital table is slightly better, after all, the oscillating pointer is a precise and flexible physical device.
Or turnip greens each have their own favourites, but what if it is a junior electrician? I comprehensive pointer multimeter characteristics or feel that this is more appropriate, although relatively troublesome, not intuitive. But our purpose is to learn and easy to understand the measured object value changes, so it is still recommended for novices to use.
