The picture below describes what an uncertain digit is fairly well. On a dial caliper, the uncertain digit is estimated between the lines on the dial. slideplayer.com/slide/4626715/15/images/5/The+measured+value+has+three+certain+digits+%281%2C+5%2C+and+6%29+and+one+uncertain+digit+%285%2C+or+is+it+4+or+6+%29..jpg
The last recorded digit, which is determined by the accuracy of the tool. If the dial needle falls between 1 and 2, we record it as a 1, although the actual number is between 1 and 2.
@@mikemarler8224 How I understood is, you choose a number between 1 to 9 for uncertain digit. It depends where the needle is between the lines. If its right in the middle of two lines then its a x.xxx5
The uncertain digit is just a guess by him. Its when the dial is in between two lines and there are no further sub lines. If the dial was on the first line .001 exactly he would write it as .0010 that last 0 is just saying he thinking it was exactly on the line. If its a little past that line he just guesses. He breaks the distance from line to line into 10 divisions in his head and guesses. If he thinks its exactly in between lines on the dial he will say its half way and add a .0005 to the reading of .001. The dial is actually only good to thousandths .001. There are no lines for ten thousandths so its just a guess which does give a little more information vs if you just rounded it off.
.999 Then u hit one inch.. so those other smaller numbers are in thousandths of an inch.. then after that then it's ten thousandths of an inch.. so if u have 2 inches 200 thousandths and 5 tenths. It would read like this 2.205 .... So read it properly.. teach the class properly... 0.000 Or 0.00 or 0.0 or 0. See the decimal placement? That tells u everything as to what your reading..
@@ethanhutchinson7888 correct I was trying to illustrate that the decimal placement matters. Tou just helped me to validate that point u caught my error. Thanks..
What are you doing, you said about reading internal measurement but you read the lower measurement? Is it not supposed to use the upper measurement?for internal measurement.
luis zavala no matter how you measure you read it the same way. Take the whole inch and tenth of an inch from the blade, then the hundredth and thousandth of an inch from the dial.
There is a fourth way to measure with a caliper using the end of the jaws. Look opposite the rod/probe to notice that when completely closed the end of the jaws are flush and as the caliper is opened a step appears. The large flats make it much easier to keep the instrument square with the feature being measured resulting in better accuracy. If the depth inside the groove at 2:36 is required the probe is the only option but care must be exercised to hold the instrument true to the part. If it is known that there are only two elevations on this part the step measurement on the outside of the raised perimeter will yield a more accurate reading.
All good info until you went into uncertain numbers. I get the 2.542,, which i think is read 2" .542 thousands. But how do you say the uncertain number?
Good video, I just got a Starlett 120 (no documentation) and saw another video where the guy said to loosen the bottom dial zero screw and the top screw for each measurement. (no kidding) I thought you just zero it and set it one time then dont mess with the bottom screw. He acted like you have to loosen and tighten both. I think maybe he thinks he is an expert in his mind putting out bad youtube intel.
Great Question. You use the "Uncertain Digit." Its a fifth digit you can use. For example, if the measurement is between 4.753 and 4.754, you can estimate it as 4.7535.
Good question. On the model I have the top side of the blade has a metric ruler. You cannot use the dial feature and can only measure to the millimeter.
No way the 4th digit matters, lol
Those calipers MAY be within .001 when brand new. 0001 is laughable.

2.205 should be read two and two hundred five thousandths. The five is not in the tenths place; it is in the thousandths.

Thank you for the intructions
There are 4 ways to measure with a dial caliper!!
Unfortunately, we need millimeters!
Thank you so much

Glad this one worked out for you!
your camera work is shocking
Where dud u got 1 sir
Good job, Sir Stem!
Is there a way to get mm's without converting? Thanks
Most dial calipers have mm on the upper part of the blade. You cannot use the dial when measuring in mms, however
@@MrStem awww I see. Thanks!
Thanks for doing this. It helped a lot.
What if the arm on the dial is right in between two lines?
Great Question. You use the "Uncertain Digit." Its a fifth digit you can use. For example, if the measurement is between 4.753 and 4.754, you can estimate it as 4.7535.
@@MrStem thanks for answering
Damn! You're always out of focus!
Very good video. impact factor 10/10!
It does not have MM?
Depends on which one you have. Most have them on top of the blade. The actual dial only works in inches
@@MrStem i bought a 15cm dial caliper..i find it hard to read bcoz its very diffirent
@@sanjoeamaranto1044 I hate metric as well.
how to do it in metric?
Good question. On the model I have the top side of the blade has a metric ruler. You cannot use the dial feature and can only measure to the millimeter.
On some dial calipers, the dial shows both scales: English and metric.
