VERNIER CALIPERS

HOW TO USE THIS APPLET

Drag left or right to adjust the caliper.
Use the left and right arrow keys to adjust the caliper.
If the arrow keys don't respond, click the cursor in the applet frame then try again.

Use the "METRIC" button or the "IMPERIAL (10 : 100)" button to have divisions of ten read in decimals.
Use the "IMPERIAL (8 : 64)" button to have divisions of eight read in fractions.
Use the "GENERAL (n : nsquared)" button and the "n DIVISIONS" button to set three to twenty divisions read in fractions.
Use the "RESET" button to restore the applet to the initial state.

For the caliper applet to work properly (on screen), one division of a unit must be a multiple of the number of divisions IN SCREEN PIXELS. As a result, inches and centimeters will not "look" the proper length on screen. This applet will still promote the concept of reading Vernier calipers.
