According to manufacturer recommendations, calibrations should be performed at which times?

• A. At the start of measurements and after completions to ensure readings are accurate
• B. Only At the Start of Measurements
• C. Only After Completions
• D. At regular intervals during the project

Answer: (A)

Calibration checks ensure readings reflect true values. Following manufacturer guidance, you establish an accurate baseline before you begin measurements and then verify accuracy again after you finish. Calibrating at the start sets the reference point, preventing biased results from any initial drift. Calibrating after completion confirms the instrument stayed accurate throughout testing, so the final data are trustworthy. Calibrating only at the start misses drift that could occur during use, calibrating only after completion wouldn’t verify accuracy during the measurement period, and while regular intervals can be helpful in some contexts, the manufacturer’s directive is to calibrate at these two specific times.
