As with most measurement tools in the field of metrology, your ultimate goal will be the highest level of precision and accuracy possible. This goal is best accomplished when all steps have been taken to make the measurement tool optimally suited to what is being measured. When considering an indicator, whether it is digital or dial, part of what you will want to focus on is the type of contact point. Many people may not realize the various types of contact points available and therefore may rely on only a couple of potential options. When the contact point on an indicator is properly adjusted by shape, material, and extension, there can be immense results in the accuracy of the final measurement. Considering the different types of indication contact points available is important to successful precision measurement.
