Study Notes
Vernier Caliper Scales
- A vernier scale gives readings in hundredths of a centimeter or thousands of a millimeter.
- A main scale gives readings in centimeters or millimeters.
Taking Readings
- To obtain the total reading, take the reading where the zero of the vernier scale coincides with a main scale line.
Vernier Caliper Errors
- Zero error refers to the difference between the zero of the vernier scale and the zero of the main scale.
- Zero error occurs when the jaws of a vernier caliper are not properly closed before taking a measurement.
Preparing the Vernier Caliper
- Close the jaws of a vernier caliper before using it to ensure accurate measurements.
Obtaining Total Readings
- The total reading is obtained by adding the main scale reading to the vernier scale reading.
