If a calibration spirometer consistently reads below the standard volume, it indicates that the device is not functioning correctly in terms of providing accurate measurements. Regular calibration ensures that the spirometer provides precise readings based on its design specifications. A consistent under-reading suggests that the equipment may have internal issues or inaccuracies caused by hardware deterioration, sensor problems, or software malfunctions.

To maintain the reliability of measurements, it is essential to address such under-readings, which implies that the spirometer is not delivering accurate assessments of lung function. Thus, the need for recalibration is a critical consideration to restore functioning, but the primary indicator is that the spirometer is indeed malfunctioning, leading to the conclusion that it requires corrective action.
