Hello everyone, today to talk to you about a vernier caliper measurement tool is the fact vernier caliper may not be as good as it unlike most entry-foot direct measurement it has some specific norms actually going to see the accuracy of its energy vernier caliper measurement accuracy is better than tape measure or a steel ruler measurement accuracy can also be accurate vernier caliper so it is a high-precision instrument used to measure the use of this kind of vernier calipers but often not necessarily everyone will use the time to use it is not necessarily everyone will see it the size of today is to teach you how to look at the size of it and how to measure the required amount measured object here how do we continue to read on Hello today is to introduce a general tradition vernier caliper vernier caliper there are two other one is Schedule type and the other is electronic these two viewing would be more direct point today is to teach how you want to see the traditional caliper because if we can understand behind a vernier caliper it is beginning to come and evolution of conventional vernier caliper fact, we it is helpful to first of all we have to see how it does in general vernier caliper precision measurement where it has usually write under the minimum precision on the smallest scale is much like you see on the screen is 0.02 0.02 it means that what two are two concepts that we need to have a reverse 1 1 Amy Amy reverse what is it that is 1mm 1mm = 0.1cm so divided by 10 is 1 cm distance is 1mm 1mm inside it will be subdivided into segments 100 the number of segments divided by it 0.01 0.01 100 therefore becomes usually often said that a so if it is 0.2 20 so that this truth seen here so that it reads 0.02 0.02 minimum measurement accuracy from the surface of the screen 2 is of course there are more precise vernier caliper 0.01 0.01 will write here is that it is the energy measure before a major to start the measurement precision vernier caliper must know where to test out the size of this amount will not go wrong here so that we know Hello what is the focus of the next chapter of this size to be how to watch it from the bottom side we place this demonstration is based on the metric sizes do see instructions under the most from 0 to 10 will start to look at the size of the start 0 baseline assumptions do I move it to ask you to look at the screen to see like this assumption is what is it with it between 18 and 19, between 0 and 18 with the 19 it means that its size is 18.XXmm here are beginning to look at a few mm suppose I move it to the middle position here with 21 of its 20 means that 20.XXmm after the decimal point depends on the row below to watch so it can directly do know a start large calipers to measure the time to do it is from 0 from 0 0 benchmark and see which position vernier above the falls as now represent between 26 and 27 with between 26 and 27 it is now less than 27 26.XXmm This time it will know that it is inside the range between 26 to 27mm of the decimal point we have to see how it actually is if we use steel ruler or measuring tape is not out of it with a vernier caliper on the amount you can do to 0.02 we're going to come back the next to see how it look here, 0 to 10 are divided off is represented by 0 to 1 where it is 0.1 to 0.9 here is the 0.2, 0.3 and so on, so finally 1mm 0 between 0.1 and 1 are divided into five equal aliquots of 5 divided by 5 is 0.1 to 0.02 so that each cell is 2 to see how the size of its large size it more directly reading the following will equal look at the small size of the small size of which will take a look above this size with the most foot cut flush from the screen looks more like we should look at the 5 position in this position saying cut flush cut 5 together representatives here the measured out is 26.5mm if we all move like this assumption is good like this see here is cut flush with the top 66 came in at over 3 3 6 grid grid What does it mean here is that it really bluntly 60 60 is equal to 66 in the coming 66 here is a look at how much is here is so 27.66 is one such way to measure like this could the beginning we may be more accustomed to between 27 and 27-28, or when looking at may be some difficulty in this matter is the way to start cf 0 0 reference do know that the great size after reading come back to look at the small size of the row below to see this with the above-foot section which scale is aligned alignment after that is done in accordance with the operational assumptions alignment scale 4 is 0.4 plus a few cells in each cell is measured 0.02 is one such way you come and try La may initially be difficult does not matter, read it several times to introduce next will Hello typically the outer diameter of the outer diameter is measured directly measured parallel to two places after the caliper is open in so doing measure the outer diameter of the sub-images to measure it directly after completion of the measurement can be measured to know the dimensions so it is out of 9 then align the scale with between 10 7 7.72 9.72 measured so it is out of such size like this is easy to do with the surface of the outer diameter measured from the surface of the course, as do also the length of the measurement approach or the thickness is measured the same way to do so the size of the outer diameter, thickness, length, etc. can be measured in this way come these two surfaces is the most commonly used inside the caliper so measured time will generally hand these two surfaces wipe clean to avoid dust or burrs here will affect the accuracy of here to give you a test Hello followed by the inner diameter of the inner diameter measurement is measured from vernier caliper measurements above a small claw to do here when after opening the caliper is from here that both surfaces do measurements demonstrate it is like this is done after seeing the inner diameter size measurement which is measured between End 73-74 pairs Qi scales 9 so that it is measured dimensions are 73.9 to do it like this measure will be used herein generally have some internal features like holes or see on the screen is concave so that in this way will to measure the measurement time of such ships slightly shake the can look the same size as there is no measurement time would do little side wipes a wiping finished work will do a general measure wipe the dust sometimes have burrs it will affect the accuracy of measurement like it out here to give you a measured depth look at Hello followed by measuring the depth of measurement is moving the cursor after the end of the caliper place by slender slender place to do this with a top surface we have seen action like this child see from the picture like this and then take the hand is facing the top down where you want to measure the movement of attention to see that here with this surface and this surface fit to do after completion of front-end fitting place to get size I remember after the amount of time it took then was down hard against the top end of this size do not let go of the hand to move it took a look now to see how much size is measured here is the comparison between 12.XX 12 with 13 close to 12 so it should be close to the size 12 and then see on the screen which is cut flush with it appears to be 3 so probably this size is 12.3mm 12.3 of course, sometimes a little, then will be precision measurements like this side measurement while adjusting , watching the size of which is also a way to let you go here, try La next to introduce is measured after class to class as measured by the back off the amount vernier caliper with two faces doing this to test how to do it in general there are classes such as lathe work more often class to see how to measure the length of the class through the caliper measurement before it faces against the top of the back side to make the operation where the top after completion after it is stuck stuck can be seen to see how much the size of the screen is closer between 5 and 66 8 are aligned so that it looks like it is measured out like this size is 5.8 in this direction as you may do little more apparent from the front end reference herein after the top surface of the rear end of the back complete with a fitting place to do stand up actions to achieve the purpose of measuring the size of the side let you go try to see La took to keep up to introduce is to purchase Notes in general vernier caliper is a high-precision product is a measurement tool for how to shop for it would suggest that it bought a little like a Japanese brand that is a very good vernier caliper is famous why it would be more expensive side it is often a reason because it vernier caliper precision adaptation will be better measurement precision work out and so will be better if there are different vernier caliper you can go to assess the precision often relatively poor actually in our hands will feel may not amount measurement precision may have run away to find because it is not good adaptation shaking so often this gap is relatively large rocking big time gap will affect the measured size It will compare recommend you consider buying made in Japan or Germany can be made here is full of good industry is very often used in Japan is also full of brand quality guaranteed here allow you to refer to the last La summarize on the calipers articles here recognize the most commonly heard is the fact we could have seen the look vernier caliper is not necessarily using it because if it is the same with the ruler is a direct comparison can know but do not know where this place is the ruler of this small scale local to see how the scale there are very detailed in the previous section are interested can go back to be here to understand you might find that after watching the film it says you still do not see how in fact there are two other forms of vernier caliper The first one is attached after the tabular type Schedule opened directly as you can see after reading this scale, small Chidi directly with a schedule to make it 100 display grid (not necessarily depend on the accuracy) can do this show will be clearer and more direct see its value after the decimal point is how much of course, you may still want to say but I'm still not Schedule type will see there is another more direct electronic type of electronic vernier caliper direct to pull it directly on the display value so we do not take the view scale has advantages and disadvantages, and so of course it is a little more in-depth here, there is no scope to explore in addition to no longer investigate to see if you have some you might need a little faster or you would like to learn traditional want to buy a vernier caliper to practice their own needs to see you to choose the appropriate vernier caliper teaching today went to the far side of teaching we look forward to it next time Bye ~ Bye ~
