生産に使用する計測器はすべて精度管理の対象となっている。
この為計測器はその精度を維持するためにその機能によって定められた方法により定期的に校正がなされます。
例えば、ノギス等の長さを測定する計測器では、高精度に加工されたゲージブロックと呼ばれる一定寸法の金属片を当該ノギスで測定し、ノギスの示す測定値とゲージブロックの値との差異が一定限度以下であることを確認します。
重さを測るはかりについては基準となる分銅、電気計器については基準となる標準電流・電圧発生器との比較によって校正を行う

All measurement instruments to be used in production are covered by the accuracy management.
Therefore, measurement instruments are calibrated periodically by the given methods according to the functions to maintain the accuracy.
For instance, in case of length measurement instruments like a caliper etc., a precisely fabricated high precision metal block with certain dimensions, so called gage block, is measured by the caliper and then the difference between the measured dimensions by the caliper and the dimensions of the gage block are verified to be within the certain values.
As to the weighing equipment and electrical instruments, calibrations are done by comparing with the standard weight and the standard electrical currency/voltage generator respectively.

All the measuring instruments that are used in production should be managed their accuracy quality.
That's why they are checked at regular intervals to keep them accurate depending on their function.
For instance, measuring tools that measures the length like a vernier micro meter are checked if the gap between the value from a vernier micrometer and that from a gauze is less than certain limitation by using the concerned vernier micrometer to measure a piece of gauze that is certain size and processed very accurately.
Measures for weight are adjusted by a weight that is standard of it. Electric meters are fixed by comparing with the standard of an electrical current and also a voltage generator.
