Definition of the Long Gauge Caliper
A caliper, also known as a vernier caliper, is a precision measuring instrument used to measure linear dimensions such as the diameter, width or length of an object.
This tool has a measuring scale on the outside and the inside that can be used to measure objects of various shapes and sizes.
The caliper consists of two main parts, namely the caliper leg and the caliper stem.
The calipers are used to measure the outside of the object, while the caliper is used to measure the inside of the object.
The calipers have a jaw or head which consists of two parts, namely the fixed jaw and the moving jaw.
The fixed jaw is an immovable part, while the mobile jaw can be moved manually.
The caliper is also equipped with a vernier scale or vernier scale which is located along the caliper stem. This vernier scale helps to improve measurement accuracy.
In some modern vernier calipers, the vernier scale is replaced with a digital display to facilitate measurement readings.
There are several different types of caliper, such as ordinary caliper, digital caliper, and caliper with magnetic holder system.
The type of caliper used depends on the type of measurement to be carried out and the needs of the user.
In use, the vernier caliper must be properly maintained and calibrated periodically to ensure that measurement accuracy is maintained.
In addition, users of vernier calipers must also have sufficient skills and knowledge on how to use this tool in order to take measurements accurately.
Calipers are very common dimensional measuring devices used in a wide variety of industrial and technical applications.
This instrument consists of several main parts that work together to perform measurements with high accuracy. Here are some of the main parts of a caliper:
1. Fixed Jaws
The fixed jaw is the part of the caliper that cannot move. This section serves as a reference point for measuring the dimensions of the object to be measured.
2. Jaws of Motion
The movable jaw is the movable part of the caliper. This section is used to place the object to be measured between the movable jaw and the fixed jaw.
3. Head of caliper
The caliper head is the part that is located at the end of the caliper.
This section serves as a place to read measurement results and also as a place to add a vernier scale to improve measurement accuracy.
4. Measurement Scale
The measuring scale is part of the vernier caliper which is located on the moving jaw. This part is used to determine the size of the measured object with an accuracy of up to 0.1 mm.
5. Vernier Scale
The vernier scale is part of the vernier caliper which is located on the vernier caliper stem.
This section serves to add a decimal number to the measurement results and improve measurement accuracy up to 0.02 mm.
6. Fastener Wheel
The fastener wheel is the part of the caliper located on the caliper head. This section is used to open and close the motion jaw when taking measurements.
7. Caliper Feet
The caliper foot is the part of the caliper which is located on the outside of the fixed jaw.
This section is used to determine the starting point for measurement and can be used to measure objects with a larger size.
How to use caliper
Here are the steps for using a caliper:
- Make sure the caliper is in good condition and properly calibrated before use
- Determine the type of measurement to be carried out and select the right part of the caliper to make the measurement
- Open the calipers by turning the fixing wheel
- Place the object to be measured between the movable and fixed jaws
- Close the moving jaws slowly by turning the fixing wheel until the object is firmly clamped
- Read the measurement scale on the calipers to determine the size of the object being measured
- Read the vernier scale on the calipers to add decimal places to the measurement. A vernier scale can help improve measurement accuracy up to 0.02 mm
- Record the measurement results obtained
- When you have finished taking the measurement, remove the jaws and store the calipers safely in a dry, dust-free place.
It is important to remember that measuring with calipers requires considerable precision and skill.
If the user does not have sufficient experience in using vernier calipers, it is better to do this with the help of someone who is more experienced or by attending training on the use of vernier calipers.
This will help minimize measurement errors and produce accurate measurement results.
Caliper Accuracy and Precision
Calipers are very accurate dimensional measuring devices and can be used to measure various types of objects with high accuracy.
However, the accuracy of vernier caliper measurements does not only depend on the quality of the tool itself, but also on the skill of the user in using it.
To ensure accurate and precise measurement results, caliper users must pay attention to several things, including:
1. Equipment Cleanliness
Before use, make sure the caliper is clean from dust, dirt or oil. Cleanliness of the tool will minimize the occurrence of measurement errors.
2. Tool Calibration
Tool calibration is very important to ensure measurement accuracy. Calibration can be carried out independently or by using the services of a calibration laboratory.
3. Position Measurement
Measurement position is very important in avoiding measurement errors. Make sure the object to be measured lies horizontally and in line with the fixed and movable jaws.
4. Pressure Measurement
Measurement pressure that is too strong or too weak can affect the measurement results. Make sure the measuring pressure is sufficient and consistent.
5. Scale Reading
Reading the scale on calipers requires accuracy and foresight in reading numbers. Make sure the scale reading is done carefully and precisely.
In using vernier calipers, there are two important terms that need to be understood, namely accuracy and precision.
Accuracy refers to how close the measurement results are to the true value, while precision refers to how close the measurement results are to one another.
To ensure the accuracy and precision of caliper measurements, it is advisable to make several measurements and take the average value.
This can minimize measurement errors that may occur.
In the use of calipers, precision and foresight are needed to ensure the accuracy and precision of measurements.
Therefore, it is important for vernier caliper users to pay attention to the things above and continue to practice skills in using it.
