Piglet muttered, \"It’s cold; we need to heat the boiler. Let me teach you a few ways to determine whether a micromanometer or an ultramicromanometer is of good quality. 1. Micropressure generally refers to positive pressure, negative pressure, and both positive and negative pressures, with a range that spans from 5000 Pa to 300 Pa. Ultramicropressure also involves positive pressure, negative pressure, and both positive and negative pressures, but its range is from 300 Pa to 25 Pa. 2. First, I’ll show you two diagrams; take a look at them. I’ll discuss tomorrow how these diagrams are related to the topic at hand.\"
Have you taken a close look at the two pictures I posted? ,,If you’re not sure, take a closer look first. Once you’re sure, the pig will mutter: First of all, is it a good micropressure gauge, or an ultra-micropressure gauge? Its positional error is extremely small! How small is it? Look at the diagram: when the pressure sensing interface is directed downward, the reading on the microbarometer is 0.000 hPa (the unit is hPa, as used in CCTV’s weather forecasts); 0.000 hPa equals 0.0 Pa. When the pressure sensing interface is directed upward, the reading becomes 0.011 hPa, which is equivalent to 1.1 Pa. The direction in which the interface is pointed – whether upward or downward – indicates that the maximum positional error is 1.1 Pa; when it is pointed in other directions, the error will be less than 1.1 Pa. A maximum positional error of 1.1 Pa – is that amazing? ,,, Xiao Cheng is just a dull little wretch, you know? The pig, who was snoring, said: \"Is it a good micropressure gauge, an ultra-micropressure gauge? Its positional error, that is, the error in its installation position, is extremely small!\" It is so small that it can be ignored relative to its precision error! Those who agree with Pig’s opinion, please reply below,,, Let’s get support first, and then Pig can mention the second, third, fourth, and Nth points. . . . . . . If you don’t agree, come and leave criticism, start arguments, or have arguments with each other {:3_51:}.
No one has replied to the post; I can only use a pig’s tail to whip its buttocks—go!

Why stop talking? Just became addicted; it’s gone
