Spirometer shows an offset in the flow rate, or a drift in the total flow.
To minimize the offset for the flow rate or drift for the total flow, make sure that the blue box amplifier for the spirometer is kept level with the text facing up. If the orientation of the amplifier box (where the transducer for determining the pressure difference is located) the weight of the diaphram can change the reading of the sensor.
