Registed user can get files related to this applet for offline access.If java program did not show up, please download and install latest Java RUN TIMEor
Check out EJS version of similar applet: Vernier Caliper and Micrometer with zero error options
This java applet shows you how to read the vernier scale on Vernier calipers.
To observe how the scales are read, click in the "checkbox" by SHOW and drag the lower scale left or right to observe how the measurement is determined.
Notice that the value for the upper scale is determined by where the 0 on the lower scale lines up with the upper scale and the number on the lower scale is determined by finding which mark on the lower scale best lines up with ANY mark on the upper scale.
To test your ability to read a measurement, leave SHOW unchecked and then drag the lower scale left or right.
The applet will wait for you to enter a value into the TextField and will then tell you whether your answer is correct.(After you type in an answer, press Enter.)
Thanks goes to Mary Ball for rewording the instructions.
This is another applet to help you understand how it works.
You can drag the lower box or use the slider to see the gap between those boxes at different level.
It is the gap which give us higher precission!
There is a similar applet : Vernier Calipers

Subject: Vernier applet Date: Tue, 31 Aug 1999 10:31:42 +0100 From: Cathal Flynn < cathal.flynn@nuigalway.ie> To: hwang@phy03.phy.ntnu.edu.tw Dear Dr. Hwang, I have used some of your physics applets and I find them to be excellent. Well done! At the moment in the Physics Department we are making changes to our first year physics labs and would like to include your Vernier applet in one of the labs in order to help the students learn to read a vernier scale properly. Is is OK if we include the applet in one experiment? Thanking you in advance, Yours Sincerely, Dr. Cathal Flynn Department of Experimental Physics National University of Ireland Galway Ireland |

Hi Assoc. Prof. Fu-Kwun Hwang, i am a Physics teacher from Singapore. I started using your applets in a Junior College and find them interesting and helpful for my students to visualise Physics concepts. presently i'm teaching in a secondary school. i've set up a site at www.angjl.per.sg/Deyi.htm and i would like to have your permission to include links to applets in your site - begining with Vernier and Vector Addition. thanks and best regards  Mr Ang Joo Liak :shock: |

Gentlemen: Many thanks for your very helpful site describing the method of reading the Vernier caliper. I recently purchased a Starrett Vernier caliper on Ebay which is in excellent condition and although I thought I knew how to "read" the instrument I was not certain. Your site was a great help in assisting me to confirm what I already thought was the correct method. Many thanks to you and Mary Ball for the clear and concise instructions. Sincerely, Taylor Mullaly tmullaly@cox.net |

Dear Mr. Hwang, I have found your Vernier caliper program very useful for checking machine operator knowledge of use the caliper. Also we've organized a measurement training for our production personnel in which we had used the program to check their skills. Thank you very much for your efforts in spreading the physics all over the world! Kind regards Janusz Ciesla MSc, Mech. Eng. ULTRATECH POLAND www.ultratech.pl |

Me dirijo a usted solicitandole información acerca de este interesantisimo applet que nos representa un vernier y me informa de una forma completamente didactica ,su manejo. Actualmente, mi hija tiene interes por aprender el uso de esta herramienta aun cuando se encuentra en educacion básica y no encuentro la forma de hacerle llegar este conocimeinto. Por lo que el programa referido es lo mejor que he encontrado, informeme cual es el precio de este apple y si necesito algun tipo de licencia para usarlo con mi hija y con quien necesite esta informacion |

Dear Mr Fu-Kwun Hwang,
Thank you for allowing me to use the vernier applet off-line. This and some of your other items are very helpful in teaching me to use the equipment, I will let others who are interested in physics to view your site and enjoy playing with the tools.
regards
Barrie

Thanks Regards matthew I have created an applet for micrometer, and I hope it is what you want. Because you did not describe it in detail. Any suggestion for improvement will be highly appreciated! |

The scale on Vernier calipers (or micrometer) was designed in a way that it is easy to read the value.
This applet was design to help you read the value. I am sorry that you did not understand it.
Use the following snap shot image of the applet as an example.
1. You will find 0. pass the 9.0 mm line so the distance is more than 9.0 mm
2. Find the line which is aligned for both rulers. Read the number from the moving ruler, which correspond to .7 mm
3. Add those two together, so you have 9.7 mm.
Is it simple enough. It is similar for the micro-meter. Use the above image as an example:
You will find the distance is more than 5.5 mm and you will find .28mm from the rotating part.
So the final result is 5.5mm+0.28mm=5.78mm
