Question

According to API, calibration is a comparison to a standard of known accuracy and making any needed adjustments

a) Once a year
b) Only if the equipment malfunctions
c) At suitable intervals
d) When requested by upper management

Answer 1

Calibration, as per API guidelines, should be performed at suitable intervals to ensure accurate and precise measurements, and to correct for any systematic errors.

Step-by-step explanation:

According to the American Petroleum Institute (API), calibration should be performed at suitable intervals. This process involves comparing an instrument or equipment to a standard of known accuracy and making any necessary adjustments to ensure precise and accurate measurements. For instance, if we are measuring the length of standard computer paper and the measurements are 11.1 in., 11.2 in., and 10.9 in., these results would be considered accurate because they are very close to the stated length of 11.0 inches. Systematic errors, such as an incorrect calibration, can lead to inaccuracies in measurements. Therefore, it is essential to calibrate instruments to maintain the reliability and accuracy of the measurement process.
