How does a micrometer compare to a caliper in terms of precision and range of lengths measured?
A micrometer has greater precision but a smaller range than a caliper
What is the significance of the initial position of the vernier caliper?
It determines whether the caliper has zero errors or not
How does Zero Error affect the actual reading measured by a caliper?
Zero Error decreases the actual reading
