Study Notes
Micrometer Screw Gauge
- A micrometer screw gauge measures the diameter of an object with an accuracy of 0.01 mm.
- The formula to calculate the reading is: 𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅 = 𝑛𝑛 × 𝐿𝐿.𝐶𝐶.
- Zero error must be checked before taking readings by closing the studs without placing anything in between.
- If the zeros collide, there is no zero error, and no correction is required.
Types of Zero Error
- Positive Zero Error: When the zero of the circular scale is lower than the zero of the main scale or index line, the error is positive.
- Negative Zero Error: When the zero of the circular scale is above the zero of the main scale or index line, the error is negative.
Correcting Zero Error
- To correct positive zero error, subtract the amount of zero error from the reading.
- To correct negative zero error, add the amount of zero error to the reading.
Vernier Caliper
- The formula to calculate the reading is: 𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅𝑅 = 𝑀𝑀.𝑆𝑆.𝑅𝑅.+ 𝑛𝑛 × 𝐿𝐿.𝐶𝐶.
- Zero error must be checked before taking readings by closing the jaws without placing anything in between.
- If the zeros collide, there is no zero error, and no correction is required.
Converting Units
- To convert a reading from centimeters to millimeters, multiply by 10. For example, a reading of 12.3 cm is equivalent to 123 mm.
