What term describes the last measurement value recorded on a dial caliper?

• A. Last measurement value recorded on a dial caliper
• B. Zero point on the dial
• C. Maximum scale reading
• D. Current measurement value

Answer: (A)

The key idea is understanding what you report after using a dial caliper. When you measure something, you read off the scales and then record that result as the measurement taken. That final value—the number you’ve just measured and saved in your notes or data sheet—is what we mean by the last measurement value recorded on a dial caliper. It reflects the actual result you’ve captured, including the fractional part shown by the dial, and it’s the value you would use for documentation or inspection. This differs from the zero point, which is merely a reference you set to establish a baseline; it doesn’t represent a measurement of the part. It also isn’t the maximum scale reading, which describes the instrument’s upper limit or range, not a specific measurement you’ve taken. The current measurement value describes the live reading you see at that moment, which is effectively the same as the last recorded value once you’ve saved it, but the form “last measurement value recorded” emphasizes the act of recording the measurement for traceability.
