Final answer:
If more than 2.5 pints of alcohol are used, the final meter reading is always adjusted using calibration factor.
Step-by-step explanation:
When more than 2.5 pints of alcohol are utilized, the final meter reading is invariably adjusted using the calibration factor. Calibration is a crucial process in measurement instruments to ensure accuracy and reliability. The calibration factor accounts for variations in the instrument's response, ensuring precise readings even in cases of higher alcohol consumption. This correction factor is determined through calibration procedures where the instrument is exposed to known standards. By applying the calibration factor, the meter reading is adjusted to reflect the true measurement, enhancing the instrument's performance and maintaining the accuracy required in applications involving the measurement of alcohol consumption or related parameters.
