1.4 Measurement, Calculations, and Uncertainties
Vernier Caliper Tutorial
Click on the "Start Simulation" button to start the
applet. Click and drag on the picture with the mouse to position the Caliper for a new
measurement. You can read the value by using the Vernier scales. To verify your
measurement, type your reading in the provided box then press the enter key. The
"Reset" key sets the Caliper at the 0.0 mm position. You can set the
Caliber on tutorial mode by selecting the "show" checkbox.
When in tutorial mode, three red arrows and number displays are provided to help you make
the reading. The first two arrows help you get the measurement in mm. The third
helps you read the decimal.
You can come back to this window by pressing the "Close Simulation" button on
the bottom frame of the utility.
The Vernier caliper is a standard method used in instruments to get
higher precision readings. As discussed in section 1.4, the method used in making a
measurement determines the accuracy with which the numbers are reported. This simulation
allows for a reading to the tenth of a mm. Calipers commonly used in industry provide an
accuracy to the hundredth of a mm.
