Vernier calipers are a versatile precision measurement tool, and mastering the correct use of each measurement part
is essential to improve measurement accuracy. Whether it is an external measuring jaw, an inner measuring jaw
or a depth gauge, they all have their own specific application scenarios and usage techniques.
Q: How to choose the accuracy of vernier calipers?
A: There are two common vernier calipers with an accuracy of 0.02mm and 0.05mm.
For general industrial applications, an accuracy of 0.02mm is sufficient. If more precision is required,
consider using a micrometer or other more precise instrument.
Q: How do maintain the vernier calipers to ensure long-term accuracy?
A: Regular cleaning, avoiding collisions, applying anti-rust oil after use, storing in a dry environment,
and regular calibration are the key steps to maintain vernier calipers.
Q: Which is more accurate, digital vernier caliper or mechanical vernier caliper?
A: Theoretically, the accuracy of both is the same. The advantage of digital vernier calipers
is that they are easier and faster to read, but you need to pay attention to battery life and water resistance.
