Which of the following best defines "Field Calibration"?

• A. Calibration only in controlled environments
• B. Calibration performed anywhere except the working site
• C. Calibration done on-site to ensure accuracy
• D. Calibration based on theoretical values

Answer: (C)

Field calibration is best defined as calibration that takes place on-site to ensure the accuracy of instruments and devices within their actual working conditions. This approach allows technicians to verify that instruments function correctly in the specific environment in which they are used, accounting for factors such as temperature, humidity, and other external variables. By calibrating instruments directly at the location where they are utilized, technicians can ensure that any adjustments made are relevant to the operational scenarios, leading to more reliable and accurate measurements. The other options do not accurately capture the essence of field calibration. Calibration in controlled environments suggests that it occurs in a lab or a controlled setting that may not represent real-world conditions. Calibration performed anywhere except the working site denotes an off-site focus, which does not consider the relevant operating conditions for accuracy. Finally, calibration based on theoretical values refers to adjustments made using calculations or standards that may not reflect practical usability, instead of actual measurements and conditions that field calibration emphasizes.
