Single-speed calibration check results from the EasyOne spirometer with the largest number of calibration checks (n = 603, serial number 47106). The actual volume differences in liters (measured minus 3.00 L) include expiratory volume errors (black diamonds) and inspiratory volume errors (white diamonds). This spirometer was not used for testing patients during the gap in measurements.
